MAX489 Datasheet PDF

●The MAX4896ETP+ is a space saving, 8-channel relay/load driver in 20 pin TQFN package. It is an 8-channel relay and load driver is designed for medium voltage applications up to 50V. The MAX4896 8-channel relay driver offers built-in inductive kickback protection, drive for latching/nonlatching or dual-coil relays and open-load and short circuit fault detection. The MAX4896 also protects against overcurrent conditions. Each independent open-drain output features a 3ohm (typ) on-resistance and has 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. Thermal shutdown circuitry shuts off all outputs (OUT_) when the junction temperature exceeds +160°C. The MAX4896 employs a reset input that allows the user to turn off all outputs simultaneously with a single control line. The MAX4896 includes a 10MHz SPI-/QSPI-/MICROWIRE compatible serial interface.
