The NCV8141 is designed for use in automotive, switch mode power supply post regulator, and battery powered systems. Basic regulator performance characteristics include a low noise, low drift, 5.0 V ±4.0% precision output voltage with low dropout voltage (1.25 V @ I OUT = 500 mA) and low quiescent current (7.0 mA @ I OUT = 500 mA). On board short circuit, thermal, and overvoltage protection make it possible to use this regulator in particularly harsh operating environments.The Watchdog logic function monitors an input signal (WDI) from the microprocessor or other signal source. When the signal frequency moves outside externally programmable window limits, a RESET signal is generated (RESET). An external capacitor (C DELAY) programs the watchdog window frequency limits as well as the power on reset (POR) and RESET delay.The RESET function is activated by any of three conditions: the watchdog signal moves outside of its preset limits; the output voltage drops out of regulation by more than 4.5%; or the IC is in its power up sequence. The RESET signal is independent of V IN and reliable down to V OUT = 1.0 V.In conjunction with the Watchdog, the ENABLE function controls the regulator’s power consumption. The NCV8141’s output stage and its attendant circuitry are enabled by setting the ENABLE lead high. The regulator goes into sleep mode when the ENABLE lead goes low and the watchdog signal moves outside its preset window limits. This unique combination of control functions in the NCV8141 gives the microprocessor control over its own power down sequence: i.e. it gives the microprocessor the flexibility to perform housekeeping functions before it powers down.VOLTAGE REFERENCE AND OUTPUT CIRCUITRY Precision Voltage ReferenceThe regulated output voltage depends on the precision band gap voltage reference in the IC. By adding an error amplifier into the feedback loop, the output voltage is maintained within ±4.0% over temperature and supply variation.Output StageThe composite PNP−NPN output structure (Figure 4) provides 500 mA (min) of output current while maintaining a low drop out voltage (1.25 V) and drawing little quiescent current (7.0 mA).Figure 4. Composite Output Stage of the NCV8141V OUTThe NPN pass device prevents deep saturation of the output stage which in turn improves the IC’s efficiency by preventing excess current from being used and dissipated by the IC.Output Stage ProtectionThe output stage is protected against overvoltage, short circuit and thermal runaway conditions (Figure 5).If the input voltage rises above 30 V (e.g. load dump), the output shuts down. This response protects the internal circuitry and enables the IC to survive unexpected voltage transients.Using an emitter sense scheme, the amount of current through the NPN pass transistor is monitored. Feedback circuitry insures that the output current never exceeds a preset limit.Figure 5. Typical Circuit Waveforms for OutputStage ProtectionILoad DumpV V Thermal ShutdownShort CircuitShould the junction temperature of the power device exceed 180°C (typ), the power transistor is turned off.Thermal shutdown is an effective means to prevent die overheating since the power transistor is the principle heat source in the IC.REGULATOR CONTROL FUNCTIONSThe NCV8141 differs from all other linear regulators in its unique combination of control features.Watchdog and ENABLE FunctionV OUT is controlled by the logic functions ENABLE and Watchdog (Table 1).Table 1. Vas a Function of ENABLE and WatchdogAs long as ENABLE is high or ENABLE is low and the Watchdog signal is normal, V OUT will be at 5.0 V (typ). If ENABLE is low and the Watchdog signal moves outside programmable limits, the output transistor turns off and the IC goes into SLEEP mode. Only the ENABLE circuitry in the IC remains powered up, drawing a quiescent current of less than 50 m A.The Watchdog monitors the frequency of an incoming WDI signal. If the signal falls outside of the WDI window,a frequency programmable pulse train is generated at the RESET lead (Figure 6) until the correct Watchdog input signal reappears at the lead (ENABLE = HIGH).The lower and upper window threshold limits of the watchdog function are set by the value of C DELAY . The limits are determined according to the following equations for the NCV8141:t WDI +(1.3 105)C DELAY or f WDI +(7.69 10−6)C DELAY −1The capacitor C DELAY also determines the frequency of the RESET signal and the POWER−ON−RESET (POR)delay period.RESET FunctionThe RESET function is activated when the Watchdog signal is outside of its preset window (Figure 6), when the regulator is in its power up state (Figure 7) or when V OUT drops below V OUT −4.5% for more than 2.0 m s (Figure 8)If the Watchdog signal falls outside of the preset voltage and frequency window, a frequency programmable pulse train is generated at the RESET lead (Figure 6) until the correct Watchdog input signal reappears at the lead. The duration of the RESET pulse is determined by C DELAY according to the following equation:t WDI(RESET)+(1.0 104)C DELAY RESET CIRCUIT WAVEFORMS WITH DELAYSINDICATEDIf an undervoltage condition exists, the voltage on the RESET lead goes low and the delay capacitor, C DELAY , is discharged. RESET remains low until output is in regulation, the voltage on C DELAY exceeds the upper switching threshold and the Watchdog input signal is within its set window limits (Figures 7 and 8). The delay after the output is in regulation is:t POR(typ)+(4.75 105)C DELAYThe RESET delay circuit is also programmed with the external cap C DELAY .The output of the reset circuit is an open collector NPN.RESET is operational down to V OUT = 1.0 V . Both RESET and its delay are governed by comparators with hysteresis to avoid undesirable oscillations.V OUT When Watchdog is Held High and ENABLE = HIGHPOR Normal OperationWDI held HighV INENABLEWDI RESET V OUT 0 V0 V 0 V BattBattPOR Normal OperationWDI held LowV INENABLEWDI RESET V OUT 0 V0 V 0 V BattBattPOR Normal OperationSlow WDI signalV INENABLEWDI RESET V OUT 0 V0 V 0 V BattBattPOR Normal OperationSleep Mode V INENABLEWDI RESET V OUT 0 V0 V 0 V BattBattWDI highPOR Normal OperationV OUT When Watchdog is Held Lowand ENABLE = HIGHV OUT When Watchdog is too Slowand ENABLE = HIGHWDI Held High After a Normal Periodof Operation; ENABLE = LOWWDI Held Low or is too Slow after a Normal Period of Operation;ENABLE = LOWPORNormal OperationSleep ModeV INENABLEWDI RESET V OUT 0 V0 V 0 V BattBattWDI lowPOR Normal OperationFigure 6.

Undervoltage Triggered RESETVAPPLICATION NOTES NCV8141 DESIGN EXAMPLEThe NCV8141 with its unique integration of linearregulator and control features: RESET, ENABLE and WATCHDOG, provides a single IC solution for a microprocessor power supply. The reset delay, resetduration and watchdog frequency limit are all determined bya single capacitor. For a particular microprocessor theoverriding requirement is usually the reset delay (alsoknown as power on reset). The capacitor is chosen to meetthis requirement and the reset duration and watchdogfrequency follow.The reset delay is given by:t POR(typ)+(4.75105)C DELAYAssume that the reset delay must be 200 ms minimum.From the NCV8141 data sheet the reset delay has a $37%tolerance due to the regulator.Assume the capacitor tolerance is $10%.t POR(min)+(4.751050.63)C DELAY0.9C DELAY(min)+t POR(min) 2.69105C DELAY(min)+0.743m FClosest standard value is 0.82 m F.Minimum and maximum delays using 0.82 m F are 220 ms and 586 ms.The duration of the reset pulse is given by:T WDI(RESET)(typ)+(1.0104)C DELAYThis has a tolerance of ±50% due to the IC, and ±10% due to the capacitor.The duration of the reset pulse ranges from 3.69 ms to 13.5 ms.The watchdog signal can be expressed as a frequency or time. From a programmers point of view, time is more useful since they must ensure that a watchdog signal is issued consistently several times per second.The watchdog time is given by:t WDI+(1.3105)C DELAYThere is a tolerance of ±20% due to the NCV8141.With a capacitor tolerance of ±10%:t WDI+(1.3105) 1.2 1.1C Delayt WDI+141ms(max)t WDI+(1.3105)0.80.9C DELAYt WDI+76ms(min)The software must be written so that a watchdog signal arrives at least every 76 ms.Figure 9. WDI Signal for C Delay = 0.82 m F usingNCV8141ms14176ENERGY CONSERVATION AND SMART FEATURES Energy conservation is another benefit of using a regulator with integrated microprocessor control features. Using the NCV8141 as indicated in Figure 10, the microprocessor can control its own power down sequence. The momentary contact switch quickly charges C1 through R1.When the voltage across C1 reaches 3.95 V ( the enable threshold), the output switches on and V OUT rises to 5.0 V. After a delay period determined by C Delay, a frequency programmable reset pulse train is generated at the reset output. The pulse train continues until the correct watchdog signal appears at the WDI lead. C1 is now left to discharge through the input impedance of the enable lead (approximately 150 k W) and the enable signal disappears. The output voltage remains at 5.0 V as long as the NCV8141 continues to receive the correct watchdog signal.The microprocessor can power itself down by terminating its watchdog signal. When the microprocessor finishes its housekeeping or power down software routine, it stops sending a watchdog signal. In response, the regulator generates a reset signal and goes into a sleep mode where V OUT drops to 0 V, shutting down the microprocessor.9.0 VFigure 10. Application Diagram for NCV8141. The NCV8141 Provides a 5.0 V Tightly Regulated Supply and Control Function to the Microprocessor. In this Application, the Microprocessor Controls its own Power Down Sequence (see text).Figure 11. Application DiagramBatteryIgnition***R ≤ 80 k W .STABILITY CONSIDERATIONSThe output or compensation capacitor C 2 in Figure 11helps determine three main characteristics of a linear regulator: startup delay, load transient response and loop stability.The capacitor value and type should be based on cost,availability, size and temperature constraints. An aluminum electrolytic capacitor is the least expensive solution, but, if the circuit operates at low temperatures (−25°C to −40°C),both the value and ESR of the capacitor will vary considerably. The capacitor manufacturers data sheet usually provides this information.The value for the output capacitor C 2 shown in Figure 11should work for most applications, however it is not necessarily the optimized solution.To determine an acceptable value for C 2 for a particular application, start with a tantalum capacitor of the recommended value and work towards a less expensive alternative part.Step 1: Place the completed circuit with a tantalum capacitor of the recommended value in an environmental chamber at the lowest specified operating temperature and monitor the outputs with an oscilloscope. A decade box connected in series with the capacitor will simulate the higher ESR of an aluminum capacitor. Leave the decade box outside the chamber, the small resistance added by the longer leads is negligible.Step 2: With the input voltage at its maximum value,increase the load current slowly from zero to full load while observing the output for any oscillations. If no oscillations are observed, the capacitor is large enough to ensure a stable design under steady state conditions.Step 3: Increase the ESR of the capacitor from zero using the decade box and vary the load current until oscillations appear. Record the values of load current and ESR that cause the greatest oscillation. This represents the worst case load conditions for the regulator at low temperature.Step 4: Maintain the worst case load conditions set in Step 3 and vary the input voltage until the oscillations increase. This point represents the worst case input voltage conditions.Step 5: If the capacitor is adequate, repeat Steps 3 and 4with the next smaller valued capacitor. A smaller capacitor will usually cost less and occupy less board space. If the output oscillates within the range of expected operating conditions, repeat Steps 3 and 4 with the next larger standard capacitor value.Step 6: Test the load transient response by switching in various loads at several frequencies to simulate its real working environment. Vary the ESR to reduce ringing.Step 7: Increase the temperature to the highest specified operating temperature. V ary the load current as instructed in Step 5 to test for any oscillations.Once the minimum capacitor value with the maximum ESR is found, a safety factor should be added to allow for the tolerance of the capacitor and any variations in regulator performance. Most good quality aluminum electrolytic capacitors have a tolerance of ± 20% so the minimum value found should be increased by at least 50% to allow for this tolerance plus the variation which will occur at low temperatures. The ESR of the capacitor should be less than 50% of the maximum allowable ESR found in Step 3 above.CALCULATING POWER DISSIPATION IN A SINGLEOUTPUT LINEAR REGULATORThe maximum power dissipation for a single output regulator (Figure 12) is:P D(max)+ǊV IN(max)*V OUT(min)ǋI OUT(max))V IN(max)I Q(1)where:V IN(max) is the maximum input voltage,V OUT(min) is the minimum output voltage,I OUT(max) is the maximum output current for the application, and11I Q is the quiescent current the regulator consumes at I OUT(max).Figure 12. Single Output Regulator With KeyPerformance Parameters LabeledV INV OUTOnce the value of P D(max) is known, the maximum permissible value of R q JA can be calculated:R q JA +150°C *T AP D(2)The value of R q JA can then be compared with those in the package section of the data sheet. Those packages with R q JA ’s less than the calculated value in Equation 2 will keep the die temperature below 150°C.In some cases, none of the packages will be sufficient to dissipate the heat generated by the IC, and an external heatsink will be required.HEATSINKSA heatsink effectively increases the surface area of the package to improve the flow of heat away from the IC and into the surrounding air.Each material in the heat flow path between the IC and the outside environment will have a thermal resistance. Like series electrical resistances, these resistances are summed to determine the value of R q JA .R q JA +R q JC )R q CS )R q SA(3)where:R q JC = the junction−to−case thermal resistance,R q CS = the case−to−heatsink thermal resistance, and R q SA = the heatsink−to−ambient thermal resistance.R q JC appears in the package section of the data sheet. Like R q JA , it too is a function of package type. R q CS and R q SA are functions of the package type, heatsink and the interface between them. These values appear in heatsink data sheets of heatsink manufacturers.PACKAGE DIMENSIONSD 2PAK−7 (SHORT LEAD)CASE 936AB−01ISSUE ODIM MIN MAX MIN MAX MILLIMETERS INCHES A 0.3960.40610.0510.31B 0.3260.3368.288.53C 0.1700.180 4.31 4.57D 0.0260.0360.660.91E 0.0450.0551.14 1.40G 0.050 REF 1.27 REF H 0.5390.57913.6914.71K L 0.0000.0100.000.25M 0.1000.1102.54 2.79N 0.0170.0230.430.58NOTES:1.DIMENSIONS AND TOLERANCING PER ANSI Y14.5M, 1982.2.CONTROLLING DIMENSION: INCH.0.0550.066 1.40 1.68P 0.0580.078 1.47 1.98R S 0.0950.105 2.41 2.67U 0.256 REF 6.50 REF V0.305 REF 7.75 REF0 8 °°0 8 °°ON Semiconductor and are registered trademarks of Semiconductor Components Industries, LLC (SCILLC).

Output voltage temperature coefficientOperation1. Basic operationFigure 12 shows the block diagram of the S-814 Series.The error amplifier compares a reference voltage V ref with part of the output voltage divided by the feedback resistors R s and R f. It supplies the output transistor with the gate voltage, necessary to ensure certain output voltage free of any fluctuations of input voltage and temperature.VOUT*1. Parasitic diodeFigure 122. Output transistorThe S-814 Series uses a low on-resistance Pch MOS FET as the output transistor.Be sure that V OUT does not exceed V IN+0.3 V to prevent the voltage regulator from being broken due to inverse current flowing from VOUT pin through a parasitic diode to VIN pin.3. ON/OFF pin (Shutdown pin)This pin starts and stops the regulator.When the shutdown pin is switched to the shutdown level, the operation of all internal circuits stops, the built-in Pch MOSFET output transistor between VIN pin and VOUT pin is shutdown, allowing current consumption to be drastically reduced. The VOUT pin enters the Vss level due to internally divided resistance of several MΩ between VOUT pin and VSS pin.Furthermore, the structure of the ON/OFF pin is as shown in Figure 13. Since the ON/OFF pin is neither pulled down nor pulled up internally, do not use it in the floating state. In addition, please note that current consumption increases if a voltage of 0.3 V to V IN−0.3 V is applied to the shutdown pin. When the ON/OFF pin is not used, connect it to the VIN pin in case of the product type is ‘”A” and to the VSS pin in case of “B”.Figure 13Table 6Product type ON/OFF pin Internal circuit VOUT pin voltage Current consumptionA “H”: Power on Operating Set value I SS1A “L”:Shutdown Stop V SS level I SS2B “H”: Shutdown Stop V SS level I SS2B “L”: Power on Operating Set value I SS14. Short-circuit protection circuitThe S-814 Series incorporates a short-circuit protection circuit to protect the output transistor against short-circuiting between VOUT pin and VSS pin.The short-circuit protection circuit controls output current as shown in “1. Output voltage vs. Output current (When load current increases)” curve in “ Characteristics”, and prevents output current of approx. 70 mA or more from flowing even if VOUT pin and VSS pin are shorted. However, the short-circuit protection circuit does not protect thermal shutdown. Be sure that input voltage and load current do not exceed the specified power dissipation level.When output current is large and a difference between input and output voltages is large even if not shorted, the short-circuit protection circuit may start functioning and the output current may be controlled to the specified amperage. For details, refer to “3. Maximum output current vs. Input voltage” curve in “ Characteristics”.Selection of Output Capacitor (C L)Mount an output capacitor between VOUT pin and VSS pin for phase compensation. The S-814 Series enables customers to use a ceramic capacitor as well as a tantalum or an aluminum electrolytic capacitor.• A ceramic capacitor or an OS capacitor:Use a capacitor of 0.47 μF or more.• A tantalum or an aluminum electrolytic capacitor:Use a capacitor of 0.47 μF or more and ESR of 10 Ω or less.Pay special attention not to cause an oscillation due to an increase in ESR at low temperatures, when you use the aluminum electrolytic capacitor. Evaluate the capacitor taking into consideration its performance including temperature characteristics.Overshoot and undershoot characteristics differ depending upon the type of the output capacitor you select. Refer to “C L dependencies of overshoot” and “C L dependencies of undershoot” in“ Transient Response Characteristics”.Precautions•Wiring patterns for VIN pin, VOUT pin and GND pin should be designed so that the impedance is low.When mounting an output capacitor, the distance from the capacitor to the VOUT pin and the VSS pin should be as short as possible.•Note that output voltage may increase when a series regulator is used at low load current (Less than 10 μA).•Generally, a series regulator may cause oscillation, depending on the selection of external parts. The following conditions are recommended for this IC. However, be sure to perform sufficient evaluation under the actual usage conditions to select the series regulator.Output capacitor (C L): 0.47 μF or moreEquivalent Series Resistance (ESR): 10 Ω or lessInput series resistance (R IN): 10 Ω or less•The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor is small or an input capacitor is not connected.•The application conditions for input voltage and load current do not exceed the power dissipation level of the package.•In determining the output current, attention should be paid to the output current value specified and footnote *3 in Table 5 in the “ Electrical Characteristics”.•Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit.•SII claims no responsibility for any and all disputes arising out of or in connection with any infringement by products including this IC of patents owned by a third party.Characteristics (Typical data)1.
