MAX895L:Dual, Current-Limited, High-Side P-Channel Switches with Thermal Shutdown

Low Resistance P-Channel Switches with Adjustable, Accurate Current Limit Protects Systems and USB

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 current-limiting 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 16µA. When the switches are off, the supply current decreases to 0.1µA. The MAX894L/MAX895L are available in an 8-pin SO package.
