MAX14916AFM+

MAX14916AFM+ is a compact industrial octal 1A/quad 2A high-side switch with diagnostics. It has eight high-side switches specified to deliver up to 1.1A (min) continuous current per channel. The two adjacent channels can be paralleled to form four 2.4A high-side switches. The high-side switches have an on-resistance of 250mohm (max) at 125°C ambient temperature. The SPI interface provides flexibility for global and per-channel configuration and diagnostic, including under-voltage detection, open wire/load detection, overload and current limiting reporting, thermal conditions reporting, and more. Integrated line-to-ground and line-to-line surge protection only requires a TVS on VDD. Integrated surge protection works for quad and octal configurations. Typical applications are industrial digital outputs, PLC systems.

• Robustness and smart diagnostics, 65V absolute maximum supply range
• Internal clamps for fast inductive load demagnetization, CRC error checking on the SPI interface
• Watchdog timer, open-wire detection, both with switches on and off
• Undervoltage detection with UVLO, loss of VDD or GND protection, thermal shutdown protection
• Integrated ±1KV/42ohm IEC61000-4-5 surge protection
• Reduces power and heat dissipation, accurate output current limiting
• Addressable SPI interface reduces isolation cost
• SYNCH input for simultaneous update of switches
• QFN48 package
• Temperature range from -40°C to +125°C
