P-Channel Switches with Thermal Shutdown
_______________General Description
The MAX891L/MAX892L smart, 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 junc-
tion temperatures.
The MAX891L/MAX892L’s maximum current limits are
500mA and 250mA, respectively. The current limit
through the switch is programmed with a resistor from
SET to ground. When the switch is on, the quiescent
supply current is a low 13µA. When the switch is off, the
quiescent current decreases to 0.1µA.
The MAX891L/MAX892L are available in 8-pin µMAX
packages.
