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.
