General Description

The FAN324x family includes dual high-current relay drivers designed to drive dual-coil polarized latching relays that connect and disconnect power in smart electronic meters and solar inverter applications.

The output of the FAN324x is rated for operation with supply voltage range from 8 V to 60 V.

The filter / timer block prevents inadvertent switching from noisy input signals by providing input-pulse qualification (tQUAL) and maximum output pulse width limit (tMAX).
