Abstract
Embodiments of the invention provide a pump control circuit for use with a pump. The pump control circuit includes a temperature sensor capable of producing a signal representative of a temperature of the pump and a microcontroller coupled to receive the signal from the temperature sensor and programmed to control a current provided to the pump. The pump control circuit also includes an output power stage coupled to receive a control signal from the microcontroller and capable of controlling the application of current to the pump in response to the control signal in order to stabilize the temperature of the pump.
