19-3843; Rev 2; 12/07 Space-Saving, 8-Channel Relay/Load Driver MAX4896 General Description Features The MAX4896 8-channel relay and load driver is Supports Up to 50V Continuous Drain-to-Source designed for medium voltage applications up to 50V. Voltage This device is offered in a 20-pin, 5mm x 5mm TQFN Guaranteed Drive Current: package, resulting in substantial board space savings. VS 4.5V The MAX4896 8-channel relay driver offers built-in 200mA (All Channels On) inductive kickback protection, drive for latching/ 410mA (Individual Channels) nonlatching or dual-coil relays, and open-load and VS 3.6V 100mA short-circuit fault detection.The MAX4896 also protectsagainst overcurrent conditions. Each independent Built-In Output Clamp Protects Against Inductive open-drain output features a 3 (typ) on-resistance, Kickback and is guaranteed to sink 200mA of load current +2.7V to +5.5V Logic Supply Voltage (VS 4.5V). RESET Input Turns Off All Outputs A built-in overvoltage protection clamp handles kick- Simultaneously back-voltage transients, which are common when dri- Built-in Power-On Reset ving inductive loads. Thermal-shutdown circuitry shuts Automotive Temperature Range off all outputs (OUT_) when the junction temperature (-40°C to +125°C) exceeds +160°C. The MAX4896 employs a reset inputthat allows the user to turn off all outputs simultaneously SPI-/QSPI-/MICROWIRE-Compatible Serial with a single control line. Interface The MAX4896 includes a 10MHz SPITM-/QSPITM-/ Serial Digital Output for Daisy Chaining andDiagnostics MICROWIRETM-compatible serial interface. The serialinterface is compatible with TTL-/CMOS-logic voltage FLAG Output for µP Interrupt levels and operates with a single +2.7V to +5.5V sup- Open-Load and Short-Circuit Detection and ply. In addition, the SPI output data can be used for Protection diagnostics purposes including open-load and short- Thermal Shutdown circuit fault detection.
