Overview
The FAN3240TMX, part of the FAN324x family, is a dual high-current relay driver designed by onsemi. This component is specifically engineered to drive dual-coil polarized latching relays, which are essential in applications that require the connection and disconnection of power, such as smart electronic meters and solar inverter systems. The device operates with supply rails ranging from 8 V to 60 V and includes a filter/timer block to prevent inadvertent switching due to noisy input signals. It also features input-pulse qualification and maximum output pulse width limit, which are factory adjustable. Additionally, the FAN3240TMX includes XOR input protection and Under-Voltage Lockout (UVLO) to ensure reliable operation.
