Introduction
The H-bridge power-transistor topology is increasingly popular as a means of driving motors and other loads bidirectionally from a single supply potential. In most cases there is great benefit in monitoring the current delivered to the load and utilizing this information in real time to provide operational feedback to a control system. In most new designs, pulse-width modulation (PWM) techniques are used to provide highly efficient variable power delivery, but ...
