Renesas Electronics Corporation ISL6146DFRZ

The ISL6146DFRZ is a low voltage OR-ing MOSFET controller in an 8-lead 3x3 DFN package, designed to replace diodes in high-current power distribution systems by driving an external N-channel MOSFET with an integrated charge pump. It operates with input voltages from 1V to 18V and provides fast reverse current protection with a 6A turn-off current, a <0.3µs turn-off response to shorts, and programmable voltage threshold adjustment via an external resistor. The device features an open-drain FAULT output and is qualified for operation from -40°C to +125°C. It meets RoHS standards and uses a Pb-free, MSL-rated package. Unlike the ISL6146A, it does not report conduction state via the FAULT pin.
