MAX14916 Compact Industrial Octal 1A/Quad 2A High-Side Switch with Diagnostics General Description Benefits and Features The MAX14916 has eight high-side switches specified to Robustness and Smart Diagnostics deliver up to 1.1A (min) continuous current per channel. 65V Absolute Maximum Supply Range The two adjacent channels can be paralleled to form four Internal Clamps for Fast Inductive Load 2.4A high-side switches. The high-side switches have Demagnetization on-resistance of 250m (max) at 125C ambient tem- CRC Error Checking on the SPI Interface perature. Watchdog Timer Open-Wire Detection, Both with Switches On and Off The SPI interface has a built-in chip addressing decoder, Undervoltage Detection with UVLO allowing communication with multiple MAX14916s utilizing Loss of V or GND Protection DD a common SPI chip select (CS). Thermal Shutdown Protection The SPI interface provides flexibility for global and Integrated 1kV/42 IEC61000-4-5 Surge per-channel configuration and diagnostic, including under- Protection voltage detection, open wire/load detection, overload and -40C to +125C Operating Ambient Temperature current limiting reporting, thermal conditions reporting, Reduces Power and Heat Dissipation and more. 250m (max) On-Resistance at T = 125C A Open load detection detects both open-wire/open-load 2mA (typ) Supply Current conditions with switches in the on and off states. LED Accurate Output Current Limiting drivers provide indication of per-channel fault, status, and Flexibility supply undervoltage conditions. Internal active clamps Addressable SPI Interface Reduces Isolation Cost allow for fast turn-off of inductive loads. SYNCH Input for Simultaneous Update of Switches Integrated line-to-ground and line-to-line surge protection LED Driver Matrix for 16 LEDs, Powered by 24V, only requires a TVS on V . Integrated surge protection DD 5V, or 3.3V works for quad and octal configuration. Flexible Logic Voltage Interface from 2.5V to 5.5V The MAX14916 is available in a compact 48-pin 6mm x Compact 6mm x 6mm QFN Package 6mm QFN package.
