onsemi FAN3180TSX

The FAN3180TSX is a single 2-A low-side MOSFET gate driver with an integrated 3.3-V, 15-mA LDO regulator for powering external microcontrollers. It is packaged in a 5-pin SOT23 and operates from 5 V to 18 V, with a thermal resistance of 161°C/W from junction to ambient on a standard PCB under natural convection. The gate driver delivers peak sink and source currents of 2.8 A and 2.5 A at 12 V supply, with a delay time of 23 ns and rise and fall times of 19 ns and 13 ns into a 1-nF load. Operating temperature ranges from -40°C to +125°C. It features TTL-compatible input thresholds, UVLO thresholds of 4.75 V turn-on and 4.55 V turn-off, and a maximum standby current of 200 µA. The device has a non-inverting logic configuration and includes thermal shutdown for safety.
