NiCd/NiMH charge controller 8-SOIC 0 to 70 with dT/dt termination

The FAN324x family includes dual high-current relay drivers suitable for driving dual-coil polarized latching relays that connect and disconnect power in smart electronic meters and solar inverter applications. The outputs of the FAN324x are rated to operate from an 8 V to 60 V supply rail. The filter/timer block provides input pulse qualification (tQUAL) and maximum output pulse width limit (tMAX) to prevent inadvertent switching of noisy input signals. These parameters are factory adjusted and other configurations are available. XOR input protection is also provided in case both outputs are on at the same time. An undervoltage lockout (UVLO) feature disables the output until the supply voltage is within operating range. FAN324x has two independent driver channels with non-inverting logic. One enable/disable pin shuts down both channels regardless of the input signal. An internal high temperature shutdown function is provided for thermal protection.

The device is used to switch inductive loads such as relays, magnetically switched incandescent lamps, and small DC motors without the need for a freewheeling diode. The device integrates all necessary items such as MOSFET switching, ESD protection and Zener clamping. It accepts logic-level inputs, so it can be driven by a variety of devices, including logic gates, inverters, and microcontrollers.
