TPS2041A, TPS2042A, TPS2043A, TPS2044A TPS2051A, TPS2052A, TPS2053A, TPS2054A are current-limited power-distribution switches from Texas Instruments. These switches are designed for applications where heavy capacitive loads and short circuits are likely to be encountered. Each channel can withstand 500 mA of continuous current and also features overcurrent logic output, thermal protection, and short-circuit protection.
The TPS2041A, TPS2042A, TPS2043A, TPS2044A, TPS2051A, TPS2052A, TPS2053A, and TPS2054A devices are current-limited power-distribution switches intended for applications where heavy capacitive loads and short circuits are likely. These devices incorporate 80-mΩ N-channel MOSFET high-side power switches designed to minimize current surges during switching using an internal charge pump.
