Abstract
A motor driver comprises a first power supply, a second power supply, a multiplexer, and an output power module. The first power supply provides a first power signal after a first period. The second power supply provides a second power signal after a second period, where the second period is longer than the first period. The multiplexer initially selects the first power signal and then selects the second power signal. An output power module controls a motor and receives power from an output of the multiplexer.
