产品概述

The MAX894L/MAX895L smart, dual, low-voltage,P-channel, MOSFET power switches are intended forhigh-side load-switching applications. These switchesoperate with inputs from +2.7V to +5.5V, making themideal for both 3V and 5V systems. Internal current-limitingcircuitry protects the input supply against overload. Thermal-overload protection limits power dissipation and junction temperature.

The MAX894L/MAX895L's maximum current limits are500mA and 250mA, respectively. The current limitthrough the switches is programmed with resistors fromSET A/SET B to ground. When the switches are on, thequiescent supply current is a low 16µA. When theswitches are off, the supply current decreases to 0.1µA.

The MAX894L/MAX895L are available in an 8-pin SOpackage.
