Overview
19-1146; Rev 2; 11/98
1A, Current-Limited, High-Side P-Channel Switch with Thermal Shutdown
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 protection limits power dissipation and junction temperatures.
The MAX890L’s maximum current limit is 1A.
The current limit through the switch is programmed with a resistor from SET to ground.
The quiescent supply current is a low 10µA.
When the switch is off, the supply curr...
