A fan having one fan blade; a fan motor for rotating the fan blade; a motor control electrically coupled with the fan motor for controlling operational characteristics of the fan motor; and a power supply having a step-down high efficiency buck converter, a step-down low drop-out linear regulator, and/or a step-down switching regulator are described. The power supply may receive a first input voltage and lower the first input voltage to a second lower voltage. The fan motor is electrically coupled to be driven by the first input voltage and the motor control is electrically coupled to operate using the second lower voltage from the power supply. The motor control may include a microcontroller, level shifters electrically coupled to the microcontroller, and drivers electrically coupled to the level shifters and configured to drive the fan motor.

Fan motor power supply

A method for resetting a key decoder coupled to a plurality of capacitive keys to prevent processing of a key code generated by a ghosting condition. The method includes receiving a key code from a key decoder that corresponds to a first capacitive key of a capacitive keypad, detecting a ghosting condition for a second capacitive key that does not correspond to the detected key code, and resetting a key decoder in response to the ghosting condition being detected.
