TI TPS2552精密电源分配方案
The TPS2552/53 and TPS2552-1/53-1 power-distribution switches are intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered. These devices offer a programmable current-limit threshold between 75 mA and 1.3 A (typ) via an external resistor. Current-limit accuracy as tight as +/-6% can be achieved at the higher current-limit settings. The power-switch rise and fall times are controlled to minimize current surges during turn on/off.
