Image of Diodes AP74701Q Ideal Diode Controller The Diodes automotive-compliant* AP74701Q provides a simple, cost effective, and fast response solution for automotive reverse voltage protection (RVP) circuits without the need for an external TVS diode.

With its wide 3.2 V to 65 V operating voltage range, coupled with a -33 V reverse voltage clamp, the device provides a small footprint solution to both 12 V and 24 V battery systems including enhanced cold crank conditions.

The AP74701Q ideal diode controller actively drives an external N-channel MOSFET to achieve a 20 mV voltage drop, thereby providing a highly efficient reverse voltage-protection solution for automotive systems.

Its optimized regulation scheme ensures immediate reverse current blocking (<0.75 µs), meeting stringent output voltage holdup requirements during transient events like ISO 7637 pulse testing.

The AP74701Q has a low 1 µA shutdown current, operates across the -40°C to +125°C ambient temperature range, and is available in the SOT28 package.
