产品概述
The TPS255x power-distribution switch is 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 500 mA and 5 A (typical)
through an external resistor. The power-switch rise and fall times are controlled to minimize
current surges during turnon and turnoff.TPS255x 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. The
FAULT logic output asserts low during overcurrent and overtemperature
conditions.
