Product Details

The MAX14914 peripheral module provides the hardware to evaluate the MAX14914 high-side/push-pull driver that operates as both an industrial digital output (DO) and an industrial digital input (DI). Refer to the MAX14914 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 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, but the user needs to adapt the signalling because this is not a standard SPI port. Another option for the user is to wire-wrap a temporary connection from their system to the pins on connector X1.

Applications

  • Configurable Digital Input/Output
  • Industrial Digital Outputs and Inputs Modules
  • Motor Control
  • Safety Systems

Product Details

The MAX14914 evaluation kit (EV kit) provides a proven design to evaluate the MAX14914/MAX14914A/ MAX14914B, a configurable industrial digital output driver/digital input. The EV kit allows controlling of the MAX14914 as either a digital output (in either High-Side or Push-Pull mode) or digital input with simple jumper settings.

The EV kit must be powered from an external +24V power supply and can consume up to 1.3A (minimum) when fully loaded.

The MAX14914EVKIT comes with a MAX14914ATE+ installed in a 16-pin, 4x4mm TQFN-EP package.

MAX14914B overcurrent interrupt output is not directly supported. For the MAX14914B application refer to the MAX14914 IC data sheet.

Applications

  • Configurable Digital Input/Output
  • Industrial Digital Outputs and Inputs Modules
  • Motor Control
  • Safety Systems
