摘要:
The H-bridge circuit with shoot through current prevention during power-up includes: a high side transistor; a low side transistor coupled in series with the high side transistor; pull down devices coupled to a control node of the high side transistor and to a control node of the low side transistor; and wherein the pull down devices are controlled by a pull down circuit including a Power On Reset circuit, monitoring the digital power supply such that the high side and low side transistors are OFF until the digital power supply has settled to a desired operating voltage.
