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.

Evaluation Kit for the MAX14912

Features and Benefits

  • Easy Evaluation of the MAX14912
  • High speed Push-Pull Digital Output
  • High Side Switch option featuring Safe-Demagnetization for Safe Turn Off of Unlimited Inductance
  • Works with USB2PMB2# or USB2GPIO# Adapter and Munich GUI Software

Product Detail

The MAX14912 peripheral module (MAX14912PMB) provides the hardware to evaluate the MAX14912 octal digital output driver. Refer to the MAX14912 IC data sheet for detailed information regarding operation of the IC.

The module can be used in various ways; Maxim sells a low-cost USB2PMB1#, USB2PMB2#, or USB2GPIO# adapter board that uses the Munich GUI software for communication through a USB cable. This is not included with this board. Alternatively, any microcontroller or FPGA with a 12-pin Pmod™-compatible connector can be used. Another option for the user is to wire-wrap a temporary connection from their system to the pins on connector X1.

The Pmod PCB dimension is just 50mm long x 20mm wide, with the width determined by the size of the X3 connector.
