... OUT Switch Output. P-channel MOSFET drain. Bypass OUT with a 0.1µF capacitor to ground. _______________Detailed Description The MAX891L/MAX892L P-channel MOSFET power switches limit output current to a user-programmed level. When the output current is increased beyond the set current level, the current is also increased ...

... If the fault short-circuit condition is not removed, the switch will cycle on and off, resulting in a pulsed output. The MAX891L/MAX892L provide a fault output (FAULT). This open-drain output goes low when in current limit or when the die temperature exceeds +135°C. During start-up, FAULT is low until the switch is fully on and no over-current condition exists.
