美信半导体 开关电源芯片, MAX1491系列, Push-Pull Driver, 8通道

The MAX14912/MAX14913 have eight 640mA smart high-side 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.
