onsemi FAN324x Smart Dual-Coil Relay Drivers
onsemi FAN324x Smart Dual-Coil Relay Drivers 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 rails from 10V to 60V. The filter / timer block in the FAN324x line prevents inadvertent switching from noisy input signals by providing input-pulse qualification (tQUAL) and maximum output pulse width limit (tMAX).
