MAX4896ETP+T

MAX4896 is a space-saving, 8 channel relay/load driver is designed for medium voltage applications up to 50V. This offers built-in inductive kickback protection, drive for latching/nonlatching or dual coil relays, and open-load and short-circuit fault detection. This also protects against overcurrent conditions. Each independent open-drain output features a 3ohm (typ) on-resistance, and is guaranteed to sink 200mA of load current (VS ≥ 4.5V). A built-in overvoltage-protection clamp handles kickback voltage transients, which are common when driving inductive loads. This employs a reset input that allows the user to turn off all outputs simultaneously with a single control line. In addition, the SPI output data can be used for diagnostics purposes including open-load and short-circuit fault detection. Application includes industrial equipment, white goods, power-grid monitoring and protection equipment, ATE.
