Product Summary
The TPS2054DR quad powerdistribution switch is intended for applications where heavy capacitive loads and short circuits are likely to be encountered. The TPS2054DR incorporates in single package four 135-mW N-channel MOSFET high-side power switch for power-distribution systems that require multiple power switches. When the output load exceeds the current-limit threshold or a short is present, the TPS2054DR limits the output current to a safe level by switching into a constant-current mode, pulling the overcurrent(OCx) logic output low. The TPS2054DR is designed to limit at 0.9-A load.
