MAX894L

19-1153; Rev 0; 10/96 Dual, Current-Limited, High-Side P-Channel Switches with Thermal Shutdown _______________General Description The MAX894L/MAX895L smart, dual, low-voltage, P-channel, MOSFET power switches are intended for high-side load-switching applications. These switches operate with inputs from +2.7V to +5.5V, making them ideal for both 3V and 5V systems. Internal currentlimiting circuitry protects the input supply against overload. Thermal-overload protection limits power dissipation and junction temperature. The MAX894L/MAX895L’s maximum current limits are 500mA and 250mA, respectively. The current limit through the switches is programmed with resistors from SET A/SET B to ground. When the switches are on, the quiescent supply current is a low 16 µ A. When the switches are off, the supply current decreases to 0.1µ A. The MAX894L/MAX895L are available in an 8-pin SO package. ____________________________Features o +2.7V to +5.5V Input Range o Programmable Current Limits o Low Supply Current: 16µ A IQ at VIN = 3.3V 0.1µ A with Switch Off o Thermal Shutdown MAX894L/MAX895L ______________Ordering Information PART* MAX894LC/D TEMP.
