Description

The RS31385 is active circuit protection device with integrated MOSFET used to limit current and voltage to safe levels during fault conditions. The current limit level can be set with a resistor between CLREF and ground. Also, the device has integrated current sense a nd provides current monitor signal. To limit the inrush current during device turn-on, the output soft start time can be set by a capacitor between SS and ground. In addition, the device provides fault indication (GOK) signal to system for monitoring and control. RS31385 can be connected in parallel for higher current applications, and current are actively shared among the device s during soft start in parallel applications. The device is available in LGA-32, 5x5 mm package. PART NUMBER PACKAGE BODY SIZE RS31385 LGA-32 5x5 mm RS31387 LGA-32 5x5 mm
