Abstract
An integrated circuit for implementing brushless DC motor control includes a substrate, a band gap temperature sensor, and a magnetic sensor. The substrate has a temperature output pin for connection to an external device and a magnetic sensor output pin for connection to the external device. The band gap temperature sensor is formed on the substrate and is configured to sense temperature and supply a temperature signal representative of the sensed temperature to the temperature output pin. The magnetic sensor is formed on the substrate and is configured to sense magnetic field variations and supply a sensor output signal representative thereof to the magnetic sensor output pin.
