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). The output can
operate in follow-input mode or maximum width mode.
These 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. The FAN324x is available in an
Lead (Pb)-Free 8-lead SOIC package.

Pin Description
1
EN
Enable input for both channels. Pull pin LOW to inhibit operation of the drivers. This input
has a precision threshold and comparator input stage.
2 5VB 5 V bypass pin for the internal 5 V regulator that provides power to the IC control circuitry.
3 IN1 Input to driver Channel 1. This input has TTL thresholds.
4 IN2 Input to driver Channel 2. This input has TTL thresholds.
5
OUT2
Relay drive output 2: Open-drain output. HIGH impedance unless required active input(s)
are present and VS is above UVLO threshold.
6 GND Ground. Common ground reference for input and output circuits.
7
OUT1
Relay drive output 1: Open-drain output. HIGH impedance unless required active input(s)
are present and VS is above UVLO threshold.
8
VS
Supply voltage. Provides power to the device. Usually connected to the bias voltage of the
relay being driven by the device.
