C T F AC TO RYData Sheet27447.2*2526 AND2536USB DUAL POWER CONTROL SWITCHESThe A2526EL/M and A2536EL/M are integrated high-side dualpower switches, optimized for self-powered and bus-powered Univer-sal Serial Bus (USB) applications. Few external components arenecessary to satisfy USB requirements. The A2526EL/EM ENABLEinputs are active high; the A2536EL/EM are active low.All devices are ideally suited for USB applications. Each switchchannel supplies up to 500 mA as required by USB peripheral devices.In addition, the switch’s low on-resistance permits achieving the USBvoltage-drop requirements. Fault current is limited to typically750 mA, satisfying the UL 25 VA safety requirements, and a flagoutput is available to indicate a fault condition to the local USBcontroller. Momentary voltage drops that may occur on the upstreamport when the switch is enabled in bus-powered applications is elimi-nated by a “soft start” feature.Additional features include thermal shutdown to prevent catastrophicswitch failure from high-current loads, undervoltage lockout to ensurethat the device remains OFF unless there is a valid input voltagepresent, and 3.3 V and 5 V logic-compatible enable inputs.These switches are provided in 8-pin mini-DIP (suffix ‘M’) and8-lead SOIC (suffix ‘L’) packages.FeaturesI 2.7 V to 5.8 V InputI Up to 500 mA Continuous Load Current per PortI140 mΩ Maximum ON-ResistanceI 1.25 A Maximum Short-Circuit Current LimitI Individual Open-Drain Fault Flag OutputsI125 µA Typical ON-State Supply CurrentI<1 µA Typical OFF-State Supply CurrentI Outputs Can be Forced Higher Than Input (off-state)I Thermal ShutdownI 2.2 V Typical Undervoltage LockoutI0.6 ms Turn On (soft-start) and Fast Turn OffI A2526 (active-high) Improved Replacement for MIC2526-1I A2536 (active-low) Improved Replacement for MIC2526-2ApplicationsI USB Hosts and Self-Powered HubsI USB Bus-Powered HubsI Hot Plug-In Power SuppliesI Battery-Charger Circuits115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-******** AND 2536USBDUAL POWER CONTROL SWITCHES2FUNCTIONAL BLOCK DIAGRAMCopyright © 2000, Allegro MicroSystems, Inc.OUT A IN GND OUT BDwg.

Configured as a high-side switch, the power switch prevents current flow in either direction if disabled. The drain body diode is discon-nected from the source when the switch is OFF allowing the output voltage to exceed the input voltage without causing current conduction. The power switch supplies a minimum of 500 mA per switch.Charge pumpAn internal charge pump supplies power to the driver circuit and provides the necessary voltage to pull the gate of the MOSFET above the source. The charge pump operates from input voltages as low as 2.7 V. The charge pump is limited to 2.5 µA to establish a controlled turn on time of typically 1 ms.DriverThe driver controls the gate voltage of the power switch. To limit large current surges and reduce the associated electromag-netic interference (EMI) produced, the driver incorporatescircuitry that controls the rise times and fall times of the output voltage. The rise time is typically 1 ms.ENABLE (EN or EN)The logic enable disables the power switch and the bias for the charge pump, driver, and other circuitry to reduce the supply current to less than 5 µA maximum when a logic high is present on EN (A2526) or a logic low is present (A2536). The proper logic level restores bias to the drive and control circuits and turns the power ON. The enable input is a compatible with both TTL and CMOS logic levels.Fault Flag (FLG)This open drain output is asserted (active low) when anovercurrent or over temperature condition is encountered. The output will remain asserted until the overcurrent or over temperature condition is removed.Current senseA sense FET monitors the current supplied to the load. The sense FET measures current more efficiently than conventional resistance methods. When an overload or short circuit isencountered, the current-sense circuitry sends a control signal to the driver. The driver in turn reduces the gate voltage anddrives the power FET into its saturation region, which switches the output into a constant-current mode and holds the current constant while varying the voltage on the load.Thermal senseAn internal thermal-sense circuit shuts off the power switch when the junction temperature rises to approximately 165°C.Hysteresis is built into the thermal sense circuit. After the device has cooled approximately 10°C, the switch turns back ON. The switch continues to cycle off and on until the fault is removed.Undervoltage lockoutA voltage-sense circuit monitors the input voltage. When the input voltage is approximately 2 V, a control signal turns OFF the power switch.2526 AND 2536USBDUAL POWER CONTROLSWITCHES5V OUT 1 V/V ENABLE 200 µs/V OUT 1 V/V ENABLE50 µs/NO-LOAD SWITCHING PERFORMANCEV OUT 1 V/V ENABLE50 µs/115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-50002526 AND 2536USBDUAL POWER CONTROL SWITCHES6CAPACITIVE-LOAD SWITCHING PERFORMANCEI OUT500 mA/V ENABLEV FAULTV OUT 2 V/1 ms/ C L = 1000 µF R L = 12 ΩCURRENT LIMITINGI OUT500 mA/V ENABLEV FAULT V OUT 2 V/1 ms/ C L = 50 µF R L = 100 ΩI OUT500 mA/V ENABLEV FAULTV OUT 2 V/1 ms/ C L = 100 µF R L = 100 Ω2526 AND 2536USBDUAL POWER CONTROLSWITCHES7I OUT400 mA/V FAULT500 ms/15 m ΩSHORT CIRCUITTHERMAL SHUTDOWNI OUT 1 A/V FAULT500 ms/ R L = 15 m ΩTHERMAL SHUTDOWNI OUT 4 A/V FAULTV OUT5 ms/ 15 m ΩSHORT CIRCUITI OUT 4 A/V FAULTV OUT2 µs/15 m ΩSHORT CIRCUITOUTPUT SHORT-CIRCUIT PERFORMANCE115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-50002526 AND 2536USBDUAL POWER CONTROL SWITCHES8OvercurrentA sense FET is employed for overcurrent conditions. Unlike current-sense resistors, sense FETs do not increase the series resistance of the current path. When an overcurrent condition is detected, the device maintains a constant output current and reduces the output voltage accordingly. Complete shutdown occurs only if the fault is present long enough to activate thermal limiting.Three possible overload conditions can occur. In the first condition, the output has been shorted before the device is enabled or between V IN has been applied. The device senses the short and immediately switches into a constant-current output.In the second condition, the short occurs while the device is enabled. At the instant the short occurs, very high currents may flow for a short time before the current-limit circuit can react .After the current-limit circuit has tripped (reached theovercurrent trip threshold) the device switches into constant-current mode.In the third condition, the load has been gradually increased beyond the recommended operating current. The current is permitted to rise until the current-limit threshold is reached or until the thermal limit of the device is exceeded. The device is capable of delivering current up to the current-limit threshold without damage. Once the threshold has been reached, the device switches into its constant-current mode.Fault Flag (FLG)The FLG open-drain output is asserted (active low) when an overcurrent or over-temperature condition is encountered. The output will remain asserted until the overcurrent or over-temperature condition is removed. Connecting a heavycapacitive load to an enabled device can cause momentary false over-current reporting from the inrush current flowing through the device, charging the downstream capacitor. An RC filter can be connected to the terminal to reduce false overcurrent reporting. Using low-ESR electrolytic capacitors on the output lowers the inrush current flow through the device during hot-plug events by providing a low impedance energy source,thereby reducing erroneous overcurrent reporting.Power dissipation and junction temperatureThe low on-resistance of the n-channel MOSFET allows small surface-mount packages, such as an SOIC, to pass large currents. The thermal resistance of these packages are highcompared to those of power packages; it is good design practice to check power dissipation and junction temperature. The first step is to find r DS(on) at the input voltage and operating tempera-ture. Next, calculate the power dissipation using:P D = r DS(on) x I 2Finally, calculate the junction temperature:T J = P D x R θJA + T A where:T A = ambient temperature °CR θJA = thermal resistance (SOIC = 108°C/W, DIP = 60°C/W ).Thermal protectionThermal protection prevents damage to the IC when heavy-overload or short-circuit faults are present for extended periods of time. The faults force these devices into constant-current mode, which causes the voltage across the high-side switch to increase; under short-circuit conditions, the voltage across the switch is equal to the input voltage. The increased dissipation causes the junction temperature to rise to high levels. The protection circuit senses the junction temperature of the switch and shuts it OFF. Hysteresis is built into the thermal sense circuit, and after the device has cooled approximately 20°, the switch turns back ON. The switch continues to cycle in this manner until the load fault or input power is removed.Undervoltage lock-out (UVLO)An undervoltage lockout ensures that the power switch is in the OFF state at power up. Whenever the input voltage falls below approximately 2 V, the power switch will be quickly turned OFF. This facilitates the design of hot-insertion systems where it is not possible to turn OFF the power switch before input power is removed. The UVLO will also keep the switch from being turned ON until the power supply has reached at least 2 V, even if the switch is enabled. Upon reinsertion, the power switch will be turned ON, with a controlled rise time to reduce EMI and voltage overshoots.Power supply considerationsA 0.1 µF ceramic bypass capacitor between IN and GND, close to the device, is recommended. Placing a high-value electro-lytic capacitor on the output terminals is also desirable when the output load is heavy. The capacitor reduces power supplytransients that may cause ringing on the input. Also, bypassing the output with a 0.01 µF to 0.1 µF ceramic capacitor improves the immunity of the device to short-circuit transients.APPLICATIONS INFORMATION2526 AND 2536USBDUAL POWER CONTROLSWITCHES9TYPICAL APPLICATIONSVIN ON/OFF A OVER-CURRENT AGROUNDUSB CONTROLLERON/OFF BOVER-BDwg.

除环保性能外,中压开关柜的热性能关系到整个开关柜能否正常工作和长期使用。

当开关柜运行电流过大、安装工艺不完善或者设计存在一定缺陷时,容易造成开关柜的温升超标,进而直接影响开关柜的安全稳定运行[2-4]。

目前,不少高校和企业研究人员对气体绝缘开关柜做了相关的研究。

张俊民等[5]对27.5 kV GIS开关柜母线室建立了传导、对流和辐射换热相互耦合的数学模型,得到了母线室内的三维温度场与气流场的分布;程显等[6-7]对SF6和N2混合气体开关柜进行仿真计算,当通入1.1倍额定电流时开关柜温升在国标规定范围内,可知SF6混合气体一定程度上可满足开关柜散热的需求。
