General Description
The MAX890L smart, low-voltage, P-channel, MOSFET
power switch is intended for high-side load-switching
applications. This switch operates with inputs from
+2.7V to +5.5V, making it ideal for both +3V and +5V
systems. Internal current-limiting circuitry protects the
input supply against overload. Thermal-overload pro-
tection limits power dissipation and junction tempera-
tures.
The MAX890L’s maximum current limit is 1.2A. The cur-
rent limit through the switch is programmed with a
resistor from SET to ground. The quiescent supply cur-
rent is a low 10μA. When the switch is off, the supply
current decreases to 0.1μA.
The MAX890L is available in an 8-pin SO package.
