Product Details

The MAX14922 evaluation kit (EV kit) provides a proven design to evaluate the MAX14922 industrial-grade high- side switch controller for ground connected resistive, inductive, and capacitive loads with diagnostics.

The MAX14922 EV kit must be powered from an external +24V power supply and can draw more than 10A when fully loaded.

The EV kit PCB comes with the MAX14922ATE+ (16 TQFN, 3mm x 3mm) device installed, and includes Si7322DN, n-channel FET and PCB space for a power FET in a TO-252/DPAK/SOT428 package, enabling easy and simple evaluation of the device with loads.

Applications

  • High-Side Switches
  • Industrial Digital Outputs
  • Motor Holding Brakes
  • Relay and Solenoid Drivers
