Totem-pole circuit driver

A totem-pole circuit driver for driving a totem-pole circuit including a high-side power device and a low-side power device which are cascade-connected, the totem-pole circuit driver comprising:

• a high-side drive circuit which drives the high-side power device;
• a low-side drive circuit which drives the low-side power device;
• a pulse generation circuit which receives a high-side input logic signal that has a first edge and a second edge, and generates a set signal for turning on the high-side power device and a reset signal for turning off the high-side power device, based respectively on the first edge and the second edge;
• a level shift circuit which transmits the set signal and the reset signal to the high-side drive circuit;
• a high-side potential detection circuit which detects a high-side reference potential;
• a high-side potential determination circuit which
• compares a value of the high-side reference potential detected by the high-side potential detection circuit with a reference voltage, and
• outputs an event signal upon detecting that the value of the high-side reference potential exceeds the reference voltage;
• and
• an on-pulse stop circuit which receives a low-side input logic signal, and validates or invalidates the low-side input logic signal based on the high-side input logic signal and the event signal, wherein
• when the high-side input logic signal is at a low level, by which the high-side power device is turned off, and upon receiving the event signal,
• the pulse generation circuit regenerates the reset signal, and
• the on-pulse stop circuit invalidates the low-side input logic signal and outputs a signal at a low level, by which the low-side power device is turned off.
