MAX14915 Compact Industrial Octal High-Side Switch with Diagnostics General Description Benefits and Features The MAX14915 has eight high-side switches specified to Robustness and Smart Diagnostics deliver up to 700mA continuous current. The high-side 65V Absolute Maximum Supply Range switches have on-resistance of 250m (max) at 125C Internal Clamps for Fast Inductive Load ambient temperature. Demagnetization CRC Error Checking on the SPI Interface The SPI interface has a built-in chip addressing decoder, Watchdog Timer for Diagnostics Checking allowing communication with multiple MAX14915s utilizing Open-Wire Detection, Both with Switches On and Off a common SPI chip select (CS). Undervoltage Detection with UVLO The SPI interface provides flexibility for global and Loss of V or GND Protection DD per-channel configuration and diagnostic, including over Thermal Shutdown Protection and undervoltage detection, open wire/load detection, Integrated 1kV/42 IEC61000-4-5 Surge overload and current limiting reporting, thermal conditions Protection reporting, and more. -40C to +125C Operating Ambient Temperature Open load detection detects both open-wire/open-load Reduces Power and Heat Dissipation conditions with switches in the on and off states. LED 250m (Max) On-Resistance at T = 125C A drivers provide indication of per-channel fault, status, and 2mA (typ) Supply Current supply undervoltage conditions. Internal active clamps Accurate Output Current Limiting allow for fast turn-off of inductive loads. Flexibility Integrated line-to-ground and line-to-line surge protection Addressable SPI Interface Reduces Isolation Cost only requires a TVS on V . DD SYNCH Input for Simultaneous Update of Switches The MAX14915 is available in a compact 48-pin 6mm x LED Driver Matrix for 16 LEDs, Powered by 24V, 6mm QFN package. 5V, or 3.3V Flexible Logic Voltage Interface from 2.5V to 5.5V Applications Compact 6mm x 6mm QFN Package Industrial Digital Outputs PLC Systems Ordering Information appears at end of data sheet. 19-100231 Rev 2 10/18MAX14915 Compact Industrial Octal High-Side Switch with Diagnostics Simplified Block Diagram VDDOK VL VA REGEN V DD V DD DRIVE + SUPPLY MONITOR READY REGULATOR MONITOR OUT8 EN VDD DRIVE + OWONSET MONITOR CRCEN OUT7 EN CONTROL MAX14915 V DD SYNCH DRIVE + COMERR MONITOR OUT6 EN DAISY V DD A0/WDEN DRIVE + WATCHDOG MONITOR A1/SYNCWD OUT5 EN VDD CS DRIVE + MONITOR SERIAL CLK INTERFACE OUT4 & EN SDI REGISTERS V DD SDO DRIVE + MONITOR FAULT OUT3 EN DIAGNOSTICS V DD V LED DRIVE + MONITOR LHS1-4 OUT2 LHS5-8 EN LED DRIVERS VDD LHF1-4 MATRIX DRIVE + LHF5-8 MONITOR OUT1 EN EN GND Maxim Integrated 2 www.maximintegrated.com LL15 LL26 LL37 LL48
