微源 LP5308B6F 36V过电压保护开关IC

General Description

The LP5308 is a power switch device provides full protection to systems and loads which may encounter large current and input over-voltage conditions.

The device contains a 135mΩ MOSFET which can operate over an input voltage range from 3.0V to 36V. The OVP will disconnect VIN and VOUT when the voltage on VIN is higher than over voltage threshold. The over-current protection could be settable using an external resistor.

When the current reaches the threshold, the device will turn off the power FET to prohibit excessive currents from causing damage. Switch is controlled by an active-low logic pin. Thermal shutdown protection is integrated which shuts off the switch to prevent damage to the part when the temperature is higher than threshold.

These parts are available in space-saving SOT23-6 package and DFN-8 package.
