FAN3241: 60V Smart Dual-Coil Relay Drivers

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 rails from 8 V to 60 V. The filter / timer block prevents inadvertent switching from noisy input signals by providing input-pulse qualification (t_QUAL) and maximum output pulse width limit (t_MAX). The parameters are factory adjustable and additional configurations are available. XOR input protection is also provided so that both outputs are prevented from being on at the same time. Under-Voltage Lockout (UVLO) function disables the outputs until the supply voltage is within the operating range.
The FAN324x has two separate driver channels with non-inverting logic. One enable / disable pin allows shutdown of both channels, independent of the input signals. Internal thermal shutdown function is provided for thermal protection.
