MAX14913

MAX14912/MAX14913 Octal High-Speed, High-Side Switch/Push-Pull Driver General Description The MAX14912/MAX14913 have eight 640mA smart highside switches that can also be configured as push-pull drivers for high-speed switching. The propagation delay from input to switching of the high-side/low-side drivers is 1µs (max). Each high-side driver has a low on-resistance of 230mΩ (max) at 500mA load current at TA = 125°C. The device is configured and controlled either through pins or the SPI interface. The SPI interface is daisy-chainable, which allows efficient cascading of multiple devices. SPI also supports command mode, for the highest detailed diagnostic information. The MAX14912 allows configuration through SPI in parallel and serial setting modes, while the MAX14913 only supports configuration through SPI in serial setting mode. Open-load detection in high-side mode detects both open-wire conditions in the switch on/off states, and LED drivers provide indication of per-channel fa...
