MAX14912/MAX14913
Octal High-Speed, High-Side
Switch/Push-Pull Driver
General Description
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. 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 fault and
status conditions. Internal active clamps accelerate the
shutdown of inductive loads fast in high-side mode.
The MAX14912/MAX14913 are available in a 56-pin QFN
8mm x 8mm package.
