MAX14917 Industrial Octal High-Side Switch General Description Benefits and Features The MAX14917 has eight high-side switches specified to Robust Solutions deliver up to 700mA (min) continuous current per channel. 65V Absolute Maximum Supply Range The high-side switches have on-resistance of 120m (typ) CRC Error Checking on the SPI Interface at 25C ambient temperature. Watchdog Timers for Monitoring SPI and SYNCH Per Channel Overload Diagnostic and Protection The device has an SPI interface that can be daisy Loss of V or GND Protection DD chained, allowing communication with multiple MAX14917 Thermal Shutdown Protection devices utilizing a common SPI chip select (CS). There Integrated 1kV / 42 IEC 61000-4-5 Surge are also per-channel overload diagnostics provided Protection through the SPI interface. Two watchdog timers provide 7kV / IEC 61000-4-2 Contact Discharge Method an additional safety check of the master-to-device connec- 30kV / IEC 61000-4-2 Air Discharge Method tivity. -40C to +125C Operating Ambient Temperature The MAX14917 features a 4 x 4 LED cross-bar matrix, Reduces Power and Heat Dissipation which provides a visual indication of channel status and 120m (typ) On-Resistance at T = 25C A overload conditions for each channel, and an integrated 2.5mA (typ) Supply Current line-to-ground and line-to-line surge protection provides Accurate Output Current Limiting robustness to the electrical stress as per IEC 61000-4-5 and requires only one TVS on V . The MAX14917 is Flexible DD available in a compact 48-pin 6mm x 6mm FC2QFN pack- SYNCH Input for Simultaneous Update of Switches age. LED Driver Matrix for 16 LEDs, Powered from 3.0V to 36V Internal Clamps for Fast Inductive Load Applications Demagnetization Industrial Digital Outputs Daisy Chainable SPI PLC Systems Flexible Logic Voltage Interface from 2.5V to 5.5V Factory Automation Pin Compatible with the MAX14915 and MAX14916 Building Automation in Daisy-Chain Configuration Industrial IoT Compact 6mm x 6mm FC2QFN Package Ordering Information appears at end of datasheet. 19-100741 Rev 0 2/20MAX14917 Industrial Octal High-Side Switch Simplified Block Diagram V V V VDDOK L A REGEN DD VDD DRIVE + SUPPLY V A READY MONITOR MONITOR REGULATOR OUT8 EN V DD DRIVE + EN MONITOR SYNCH OUT7 CONTROL EN CRCEN V DD COMERR DRIVE + MONITOR OUT6 EN SPIWD VDD WATCHDOGS SYNCHWD DRIVE + MAX14917 MONITOR OUT5 EN VDD DRIVE + CS MONITOR CLK SERIAL OUT4 EN INTERFACE SDI VDD DRIVE + SDO MONITOR FAULT OUT3 OVERLOAD EN DIAGNOSTIC V DD V LED DRIVE + MONITOR LHS1-4 OUT2 LHS5-8 LED EN DRIVERS V DD LHF1-4 MATRIX DRIVE + LHF5-8 MONITOR OUT1 EN GND 19-100741 www.maximintegrated.com Maxim Integrated 2 LL15 LL26 LL37 LL48
