1. A squib driver circuit for deployment of a deployable restraint in a vehicle, the squib driver circuit comprising:
an integrated circuit formed on a single chip including:
an input terminal for receiving an input voltage used to fire the deployable restraint,
a high side feed terminal configured for communication with the deployable restraint, a low side return terminal configured for communication with the deployable restraint,
a high side driver configured to supply current from the input terminal to the high side feed terminal, and
a low side driver configured to supply current from the low side return terminal to an electrical ground; and
a voltage regulator configured to regulate the input voltage at the input terminal to a minimum firing voltage to deploy the deployable restraint, wherein the voltage regulator includes at least one circuit component independent of the integrated circuit.
