TPS2552-1 可调节限流配电开关

TPS2552-1 描述

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 and provide up to 1.5 A of continuous load current. These devices offer a programmable current-limit threshold between 75 mA and 1.7 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.

TPS2552/53 devices limit the output current to a safe level by switching into a constant-current mode when the output load exceeds the current-limit threshold
