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.

Abstract: An apparatus includes a circuit that has a normal mode of operation and a low-power mode of operation. The circuit consumes more power in the normal mode of operation than in the low-power mode of operation. The apparatus further includes a power-supply circuit. The power-supply circuit provides a normal supply voltage to the circuit in the normal mode of operation. The power-supply circuit includes a non-linear circuit to provide a compressed supply voltage to the circuit in the low-power mode of operation, wherein the normal supply voltage is greater than the compressed supply voltage.
