Abstract
In one aspect, a control circuit to control a speed of a motor includes a control logic circuit connected to a multifunction port. The control logic circuit is configured to receive a control signal provided at the multifunction port and to provide response signals based on the control signal to place the motor in at least two of a sleep mode, a brake mode and a pulse-width modulation (PWM) mode. The motor control circuit also includes an H-bridge circuit configured to control the motor based on the response signals.

A control circuit to control a speed of a motor, comprising:
- a multifunction port configured to receive a control signal;
- a control logic circuit connected to the multifunction port, the control logic circuit being configured to receive the control signal provided at the multifunction port and to provide response signals based on the control signal to place the motor in at least two of a sleep mode, a brake mode and a pulse-width modulation (PWM) mode;
- and
- an H-bridge circuit configured to control the motor based on the response signals.
