Fault protected self-oscillating driver |
摘要 |
A driver circuit for a transistor provides a soft start feature where pulses provided to the transistor are varied in duration during startup. The driver also provides an overcurrent protection feature for disabling a driver output for a safe period of time when an overcurrent condition is detected. The driver circuit includes an oscillator that produces a saw tooth wave and a narrow width pulse train for determining pulse width and dead time, respectively. The driver circuit may be used in half-bridge or full-bridge drivers.
