MAX14912/MAX14913 Octal High-Speed, High-Side Switch/Push-Pull Driver General Description Benefits and Features The MAX14912/MAX14913 have eight 640mA smart high- Low Power and Heat Dissipation side switches that can also be configured as push-pull 230m (max) High-Side R at T = 125C ON A drivers for high-speed switching. The propagation delay High-Efficiency 5V/100mA Buck Regulator from input to switching of the high-side/low-side drivers is Fast Switching Ideal for High-Speed Control Systems 1s (max). Each high-side driver has a low on-resistance 0.1s (typ.) Propagation Delay (High-Side Mode) of 230m (max) at 500mA load current at T = 125C. A 0.5s (typ.) Propagation Delay (Push-Pull Mode) 200kHz Switching-Rate Capability in Push-Pull Mode The device is configured and controlled either through pins or the SPI interface. The SPI interface is daisy-chainable, Fast Inductive Load Demagnetization which allows efficient cascading of multiple devices. SPI Robust Operation also supports command mode, for the highest detailed 60V Abs Max V Rating DD diagnostic information. The MAX14912 allows configuration Safe-Demagnetization: Turn-Off of Unlimited through SPI in parallel and serial setting modes, while Inductance the MAX14913 only supports configuration through SPI in IEC61000-4-2 12kV Air Gap/8kV Contact ESD serial setting mode. Protection 1kV/42 Surge Protection with TVS on V Open-load detection in high-side mode detects both DD Robust SPI Interface with Watchdog and CRC open-wire conditions in the switch on/off states, and -40C to +125C Ambient Operating Temperature LED drivers provide indication of per-channel fault and Range status conditions. Internal active clamps accelerate the shutdown of inductive loads fast in high-side mode. Extensive Diagnostics Reduces System Downtime Per Driver and Chip Thermal Shutdown The MAX14912/MAX14913 are available in a 56-pin QFN Open-Wire Detection in High-Side Mode 8mm x 8mm package.
