Abstract
A motor controller comprises a switch circuit, a control circuit, and a function pin. The switch circuit is coupled to a motor for driving the motor. The control circuit generates a plurality of control signals to control the switch circuit. The function pin is coupled to the control circuit for receiving a function signal. The function signal is configured to inform the motor controller to execute a braking function. The braking function enables a braking time to be a variable value.
