TPW5203 详细介绍

General Description
The TPW5203 are Current Limited P-channel MOSFET power switches designed for high-side load-switching applications. The internal current-limiting circuit protects the input supply against large output short circuit current which may cause the supply to fall out of regulation.The current limit threshold is programmed with an external resistor from SET Pin to ground.The quiescent supply current is typically 8µA, making the device ideal for portable battery-operated equipment. In shutdown mode, the supply current decreases to less than 0.1µA.
Additional features include thermal shutdown to prevent catastrophic switch failure from high current loads, under- voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present.
The TPW5203 are available in 5 pin SOT-23 packages.
