Methods and apparatus for transistor health monitoring

Abstract:

Methods, apparatus, systems and articles of manufacture are described for transistor health monitoring. An example gate driver includes a request receiver pin, a measurement transmitter pin, and a driver control logic pin, the request receiver pin, the measurement transmitter pin, and the driver control logic pin configured to be coupled to a controller, a sensing pin, the sensing pin to be coupled to a sensing circuit, a control logic circuit having an input coupled to the request receiver pin, a transistor coupled to the control logic circuit and the sensing pin, a multiplexer coupled to the control logic circuit and the sensing pin, an analog-to-digital converter (ADC) coupled to the multiplexer and the measurement transmitter pin, and a driver control logic circuit coupled to the driver control logic pin.
