MAX4896ETP+ PMIC Power Management ICs S34ML02G200TFI000 BCM88381CA1KFSBG Door Gate Drivers

General Description

The MAX4896 8-channel relay and load driver is designed for medium voltage applications up to 50V. This device is offered in a 20-pin, 5mm x 5mm TQFN package, resulting in substantial board-space savings. The MAX4896 8-channel relay driver offers built-in inductive kickback protection, drive for latching/nonlatching or dualcoil relays, and open-load and short-circuit fault detection.

The MAX4896 also protects against overcurrent conditions. Each independent open-drain output features a 3Ω (typ) on-resistance, and is guaranteed to sink 200mA of load current (VS ≥ 4.5V).

A built-in overvoltage-protection clamp handles kickbackvoltage 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. The serial interface is compatible with TTL-/CMOS-logic voltage levels and operates with a single +2.7V to +5.5V supply. In addition, the SPI output data can be used for diagnostics purposes including open-load and short-circuit fault detection. The MAX4896 is offered in the extended (-40°C to +85°C) and (-40°C to +125°C) operating temperature ranges.
