The MAX4820/MAX4821 8-channel relay drivers offer built-in kickback protection and drive +3.3V/+5V nonlatching or dual-coil-latching relays. These devices are especially useful when driving +3V relays. Each independent open-drain output features a 2Ω on-resistance and is guaranteed to sink 70mA (min) of load current. Both devices consume less than 50µA (max) quiescent current and have 1µA output off-leakage current. The MAX4820 features an SPI™-/QSPI™-/MICROWIRE™compatible serial interface. Input data is shifted into an 8bit shift register and latched to the outputs when CS transitions from low to high. Each data bit in the shift register corresponds to a specific output, allowing independent control of all outputs. The MAX4821 features a 4-bit (A0, A1, A2, LVL) parallel-input interface. The first three bits (A0, A1, A2) determine the output address, and the fourth bit (LVL) determines whether the selected output is switched on or off. Data is latched to the outputs when CS transitions from low to high. Both devices feature separate set and reset functions that allow the user to turn on or turn off all outputs simultaneously with a single control line. Built-in hysteresis (Schmidt trigger) on all digital inputs allows this device to be used with slow rising and falling signals, such as those from optocouplers or RC power-up initialization circuits. The MAX4820/MAX4821 are available in 20-pin TSSOP and space-saving 20-pin thin QFN packages.

General Description
The RT4812 allows systems to take advantage of new battery chemistries that can supply significant energy when the battery voltage is lower than the required voltage for system power ICs. By combining built-in power transistors, synchronous rectification, and low supply current; this IC provides a compact solution for systems using advanced Li-Ion battery chemistries. The RT4812 is a boost regulator designed to provide a minimum output voltage from a single-cell Li-Ion battery, even when the battery voltage is below system minimum. In boost mode, output voltage regulation is guaranteed to a maximum load current of 2.1A. Quiescent current in Shutdown Mode is less than 1A, which maximizes battery life.
OCP The converter senses the current signal when the high-side P-MOSFET turns on. As a result, the OCP is cycle by-cycle current limitation. If the OCP occurs, the converter holds off the next on pulse until inductor current drops below the OCP limit.

Input Socket,Pg. 4Output Terminals,Pg. 4Wiring Access Port,Chassis Grounding Stud,Pg. 5Remote Alarm Contacts,Pg. 63I) OverviewThe PM Series Power Module is a uniquely adaptable communicationequipment power source which functions as either power supply or batterycharger for 12 volt d.c. systems positive, negative or floating ground.Power Modules may be employed singly or in combina t ion. Units maybe paral l eled for N + 1 redundancy and alarm contacts allow local orremote mon i toring. An optional d.c. wiring quick connect kit allows easyreplacement of modules while the system as a whole remains up andrunning (see section V-B).Power Modules may be used separately as a power source, or they maybe integrated with NEWMAR’s Power Function Manager (model PFM-400;rated to 400 amps maximum) to greatly expand the system capability withother functions such as digital output monitoring, multiple load distributionand low voltage disconnect. (Contact the factory for complete informationregarding the PFM-400.) Note: If the Power Module is being installedas part of an integrated system with the PFM-400 refer to the manualwhich comes with that unit for all d.c. wiring instructions and functionaldescriptions.II) AC Power Quality and EMI CompatibilityA) AC Power QualityReliability is of prime concern when designing an AC-DC powersystem for communication sites. Poor AC input power qualitycan seriously impede system reliability. In particular, transientdisturbances on the power lines can severely weaken or causefailure of semi-conductors in power supplies and communicationgear. It is important that you know the input power quality wheninstalling the PM. Following is some basic information on thesubject:CausesTransients are characterized as a voltage pulse of high energy and veryshort duration impressed upon the AC wave form. These over voltagepulses can range from 1 to 100 times the normal AC voltage level and canlast for a fraction of a cycle to a few cycles.Transient disturbances can be placed into two categories:- Lightning generated- Equipment generatedA direct lightning hit on a utility power line will cause a high energy voltagetransient to travel in both directions along the power line. This disturbancecan affect equipment hundreds of miles from the strike point.Equipment generated transient sources include utility fault conditionsand load switching as well as on-site equipment such as pumps and airconditioning loads, motors, phase control equipment.RecommendationsAll PM models are designed to meet IEEE 587/ANSI C62.41 requirementsfor transient withstand capability. The AC power source should conform tothis specification to ensure reliable power supply operation.If the power source quality is suspect or unknown, it is recommended thatan AC power quality survey be conducted by a power quality consultantor power conditioning firm. Corrective measures may include lightningsuppressors, line conditioners and filters.An optional AC transient suppressor (see OPTIONS section) isrecommended for installations in third world countries and sites that aresubject to nearby lightning strikes or transients caused by nearby motorcontactors, air conditioning compressors, etc.B) EMI (Electro-Magnetic Interference) ConsiderationsThe PM Series Power Modules employ switch-mode technology to con-vert AC to DC. They are designed to produce minimal EMI levels whenoperating (compliant to International Standards EN55022 [conducted]and EN50082 [immunity]). Although the level of EMI produced may beacceptable for most radio applications, some installations may not eventolerate what little EMI is produced.Analog microwave and other extremely sensitive radio sites mayrequire additional input/output filtering and careful installation. In somecases linear power supplies (also available from NEWMAR) should beconsidered, as they emit lower EMI (although they are more susceptible to“brown-outs” or voltage sags and high input voltage).C) Other FactorsSome of the various factors which must be considered when discussingelectrical interference include the following:- RF Signal strength- Ground loops- Power and signal cable routing proximity- Power supply and radio mounting locations- Antenna, signal, and power groundsIII) InstallationA) Materials ProvidedPrior to installation, check to ensure that each of the following items havebeen included with the packaging. For any missing items please contactthe factory or warehouse.(2) ea. mounting brackets for 19” rack mounting (# 13917-0)(2) ea. mounting brackets for 23” rack mounting (# 13918-0)(6) ea. 6-32 X 3/8” pan head phillips screws(1) ea. Molex “pigtail” connector(1) ea. IEC 115V NEMA 5-15P AC input power cord(1) ea. Installation/Operation manual(1) ea. Output terminal coverB) MountingThe PM is provided with two pairs of mounting ears: one for 19” rackmounting (# 13917-0) and one for 23” rack mounting (# 13918-0). Six #6-32 x 3/8” pan head Phillips screws are provided for attaching the earsto the PM chassis. Select the appropriate set of ears and fasten to the PMsides.Note there are three sets of a triangular pattern of 6-32 tapped holeson each side of the PM. When rack mounting (two posts) the PM it isrecommended that the ‘center mount’ holes (6” set back from the PM’sfront panel) be used. The set of holes nearest the front panel and theset nearest the rear panel are normally used when installing the optionalUniversal Mounting Bracket (UMB).For four post mounting, please contact the factory for a second set of ears(specify 19” or 23” and the model no.), mount one pair of ears to the frontholes and the second pair of ears to the center or rear most tapped holes.Adjust your cabinet rail front to back distance so it matches the mountingholes on the PM.4Note: Due to the weight of the Power Module, we do not recommend flush mounting the PM with the mounting ears attached to the forward most mounting holes unless rear support is provided.C) AC Input WiringInput Wiring: PM-12-40A is provided with an IEC power cord (in theinstallation kit) with a NEMA 5-15 plug for a 115V AC outlet on one end and a molded socket at the other which fits the entry module at the rear of the PM. If the 5-15 plug is not suited to the available AC outlet, 1) obtain an IEC cord with appropriate plug or 2) cut off the 5-15 plug, obtain the correct plug for the outlet and attach it to the provided IEC cord. (Plug should be rated at 15 amps minimum). When replacing the plug, pay careful attention to the pin wiring as follows:Brown.........................AC Hot (over-current protected) Blue............................AC NeutralGreen*........................AC Ground (safety, earth) * may be Green with Yellow StripeInput Voltage Selection: The PM-12-40A is universal input. No switch required and will accept input of 90-264 VAC, 47-63 Hz.Important: Although the internal AC wiring is protected by the front panel mounted circuit breaker, the wiring to the PM must also be protected by plugging into an appropriate over-current protected three prong outlet or routed through a separate dedicated fuse or circuit breaker on an AC distribution panel with proper safety/earth chassis ground in accordance with all applicable codes and ordinances.Distribution Panel AC Fuse/Circuit Breaker Values 15 ampCAUTION (230 V a.c applications only): If AC input is derived from a source consisting of two HOT leads (phase-to-phase 230V AC inputvoltage), an external fuse or circuit breaker (double pole) must be used to protect the unfused (formerly NEUTRAL, now HOT) lead.D) DC Output WiringIMPORTANT: Ensure that AC input to the PM is switched off beforeworking with DC wiring. The output terminals are “hot” whenever the unit is switched on.1) Output terminals for hard-wiring of DC output are located on the rear panel of the PM. Terminate wires with 1/4” ring lug connectors for a secure installation.2) Use the chart below to determine minimum gauge for wires depend-ing on the particular model and the length of the run from the PM to the load or distribution bus (or refer to N.E.C or local codes for any questions regarding proper DC wire gauges):DC Wire Size Table:Model Minimum Wire Size per N.E.C. AWG (mm) PM-12-40A: #8 (10 mm)To minimize line loss at lengths greater than 5 feet, it is recommended to increase wire size one gauge for each additional 5 feet of cable run.3) Two separate (+) output terminals are provided. Connection of d.c. wiring is typically made to the (-) output and the “V OUT” (+) output ter-minal, though “V2” (+) may be used instead if the application requires it (see “V2” below).“V OUT” (+) Terminal: This output is routed through an internal “or-ing”/isolation diode. This terminal should be used for most installations. Use of this terminal is mandatory when the PM is wired for parallel n+1 redundant operation, or when it is used as a battery charger. Regula t ion at this terminal is 2 % line/load. Note: When the PM is used in a parallel n+1 redundant configuration, output current is derated by 10 % due to current sharing tolerances (see SPECIFICATIONS section).“V2” (+) Terminal: This is a direct output without the internal oring/isolation diode in line. 1 % regulation is available at this terminal and it should only be used in installations where only a single PM is used, 1 % regulation is required and the PM will not be wired to a battery. Output voltage measured at this terminal is approximately 0.7V d.c. higher than at the “V OUT” terminal.Typical single PM wiring schemes are illustrated in Figures 5-6.FIGURE 5: Single Power Module, negative ground, with battery:Figure 6: Single Power Module, negative ground, no battery, 1% regulation required:(-) Negative to Load or Ground Bus Bar(+) Positive to Load or Distribution Panel>>(+) Positive to Load or Distribution Panel(-) Negative to Load or Ground Bus Bar5E) Parallel WiringThe internal oring/isolation diode of the PM allows parallel n+1 redundant wiring with no modification or other external isolation de v ices required. Figure 9 on the following page illustrate some typical parallel wiring schemes.IMPORTANT: When wiring two or more units in parallel d.c. wires for all units should be identical in gauge and length and the output voltage of each module should be adjusted (as outlined below) in order to facilitate droop load sharing.Parallel Load Sharing Adjustment Procedures Method 1:1) Shut off all but one of the Power Modules and apply a load equivalent to 1/2 of the rating for that unit (e.g., for model PM-12-40A apply a 20 amp load).2) Connect a digital voltmeter to the test points on the front of the power module at the “V OUT” and (+) and (-) positions.3) Verify that the output voltage is at the correct factory setting (see Specifications section) or at the desired system voltage. If adjustment is neces s ary, use a small flat tip screwdriver to turn the “OUTPUT VOLTAGE ADJUST” potentiometer on the front panel until the voltmeter reads the desired system output voltage.4) Shut off the PM, turn on the next unit in the system, and repeat steps 2 through 4 until all PM’s in the system have the identical “V OUT” output voltage.Method 2:1) With all Power Modules powered up, apply the typical operational d.c. system load.2) Using a clamp-on ammeter, measure the output current of each PM in the system. If there is an out-put current differential of greater than 5 % between any two PM’s, attach the ammeter to the PM with the highest output current and turn the “OUTPUT VOLTAGE ADJUST” potentiometer on that unit slowly counterclockwise, until the output current of that unit reduces slightly.3) Repeat step 2 until there is less than 5 % current output differential between all PM’s in the system.F) Chassis GroundingIf grounding of the PM chassis is required for theinstallation, use the provided 1/4” grounding stud on the rear panel for this purpose (see Figure 2 or 3).FIGURE 6: Parallel (two to three Power Modules) and N+1 redundancy, negative ground V) Operation A) AC InputThe PM will operate on 90-264 VAC input at 47-63 Hz. No input voltage selection or adjustment is required for 115/230 VAC, 50 or 60 Hz. operation.AC input is protected against over-current and internal short circuit condi t ions by the circuit breaker/input power switch on the front panel. When this switch is in the on position and DC is available at the output terminal, the “ON” indicator L.E.D. on the left side of the front panel will illuminate.B) DC OutputThe PM produces 12 VDC nominal output. The ground reference may be positive, negative or floating.Regulation: Regulation at the “V OUT” output terminal is within ± 2 % of rated voltage, under all line and load conditions. Regulation at the “V2” terminal is ± 1 %. Ripple is within ± 1 % of rated voltage with or without batteries on-line.Output Voltage Adjust: Factory-set voltages (as measured at the V OUT terminal) and approximate adjustment ranges are specified below. Adjust m ent is made at the “OUTPUT VOLTAGE ADJUST” pot on the left side of the front panel using a small flat tip screwdriver (see Figure 1). Output voltage test points for both the “V OUT” and “V2” outputs areprovided beside the voltage adjust pot for ease of monitoring while making this adjustment. Use of a digital multimeter is recommended when making this adjustment. If the PM has had the charger function board installed, output voltage adjustments are automatic and this adjustment pot is disabled.••••○○>(+) Positive to Distribution Panel or Battery (fuse at battery per N.E.C. or local codes)Power Module #1Power Module #2Power Module #3<<<(-) Negative to Loads or BatteryIf the battery is connected to the PM output with backwards polarity, the fuses should blow to protect DC wiring. However damage to internal components may also have occurred. If the replacement fuse blows, return To maximize the life of the internal components and to allow continu o us operation at full rating, the PM employs automatic cooling fans.
