Abstract: A squib driver circuit for deployment of a deployable restraint in a vehicle. The safety restraint may have a minimum firing voltage. The voltage regulator may regulate the input voltage to be the minimum firing voltage at the input terminal. The squib driver circuit may be formed on a single chip. The squib driver circuit may include a high side driver and a low side driver. An input terminal for receiving an input voltage used to fire the deployable restraint. The high side driver may supply current from the input terminal to the deployable restraint. The low side driver may supply current from deployable restraint to the electrical ground.

Abstract: A squib driver circuit for deployment of an active safety restraint in a vehicle. The squib driver circuit may include a high side protection circuit. The high side protection circuit may include a comparator circuit to compare the input voltage to a reference voltage and activate a timer in response to the input voltage exceeding the reference voltage, the timer generating a disable signal to disable the high side driver after a predetermined period of time The high side protection circuit may disable the high side driver after a short is detected and elapse of the predetermined period of time. The squib driver circuit may be formed on a single chip.

Abstract: A squib driver circuit for deployment of an active safety restraint in a vehicle. The squib driver circuit may include a high side protection circuit. The high side protection circuit may include a comparator circuit to compare a voltage at a high side feed terminal to a reference voltage and activate a timer in response to the voltage at the high side feed terminal exceeding the reference voltage, the timer generating a disable signal to disable the high side driver after a predetermined period of time. The high side protection circuit may disable the high side driver after the short is detected and elapse of the predetermined period of time. The squib driver circuit may be formed on a single chip.

Abstract: A squib driver circuit for deployment of an active safety restraint in a vehicle. The squib driver circuit may include a low side protection circuit. The low side protection circuit may include a comparator circuit to compare a voltage at a low side return terminal to a reference voltage and activate a timer in response to the voltage at the low side return terminal exceeding the reference voltage, the timer generating a disable signal to disable the low side driver after a predetermined period of time. The low side protection circuit may disable the low side driver after the short is detected and elapse of the predetermined period of time. The squib driver circuit may be formed on a single chip.
