Full Bridge DC Motor Driver ICs SPF7301
(under development)
Features
A DMOS of low ON resistance (0.1Ω typ) is mounted on the high and low side
power elements
Two input signals control the forward/reverse/brake of a DC motor
Current limit and overcurrent protection circuits
Low voltage and thermal protection, excess input detecting output and input
terminal open protection
