Abstract:
1. A controller for controlling a power chain in an electronic device, comprising: a sensor that detects an application signal indicating whether the controller is in a first application requiring the controller to produce drive signals for driving discrete power MOSFETs, or a second application requiring the controller to produce an output PWM signal to control an integrated circuit having power MOSFETs integrated with MOSFET drivers; a first output, which produces a first drive signal and is for connecting to a first power MOSFET, when the controller is in the first application; and a second output, which produces a second drive signal and is for connecting to a second power MOSFET, when the controller is in the first application, and which produces the output PWM signal and is for connecting to a PWM input of the integrated circuit, when the controller is in the second application.
