Abstract: An apparatus includes a first set of circuits adapted to operate in a first mode of operation of the apparatus. The apparatus further includes a second set of circuits adapted to operate in a second mode of operation of the apparatus, where a power consumption of the apparatus is lower in the second mode of operation of the apparatus than in the first mode of operation of the apparatus. The apparatus also includes a charge pump adapted to convert a first supply voltage of the apparatus to a second supply voltage, and the second supply voltage powers the second set of circuits.

Abstract: A motor control apparatus to control a motor external to the motor control apparatus includes a microcontroller unit (MCU). The MCU includes mixed signal motor control circuitry adapted to perform back electromotive force (EMF) motor control in a first mode of operation. The mixed signal motor control circuitry is further adapted to perform field oriented control (FOC) in a second mode of operation.
