Product Details

The MAX14919 evaluation kit (EV kit) provides a proven design to evaluate the MAX14919 industrial-grade quad low-side switch with 140mΩ (typ) RON and ±1kV/42Ω surge protection.

The MAX14919 EV kit features an isolated power and signal interface to provide pin-level control of the four lowside switches in the MAX14919. The EV kit also features reverse-current protection to prevent damage caused by miswiring faults at output and return terminals.

The EV kit comes with the MAX14919AUP+ (20 TSSOP-EP, 6.5mm x 6.4mm footprint) device installed.
