摘要： A microcontroller unit includes a processor for generating a first control signal to start a comatose mode of operation for the microcontroller unit. Control logic responsive to the first control signal generates an enable signal at a first level and the control logic is further responsive to a second control signal for generating the enable signal at a second level. A voltage regulator generates regulated voltage from an input voltage. The voltage regulator shuts down to provide a zero volt regulated voltage responsive to the enable signal at the first level and powers up to provide a regulated voltage at an operating level responsive to the enable signal at the second level.

摘要： A digital controller for controlling the operation of a DC-DC switching converter is disclosed. A digital feedback control system is provided for receiving an analog input voltage representing the output of the switching converter and digitally processing the analog input voltage by comparing it to a reference voltage and then determining analog drive signals to control the operation of the switching converter to provide a regulated output. The digital feedback control system operates in accordance with predetermined operating parametrics. The digital feedback control system also has monitoring inputs and control inputs. A microcontroller monitors the operation of the digital feedback control system and is able to change the operating parametrics under certain predetermined conditions.

摘要： Circuits and methods for controlling Pulse Width Modulation (PWM) input of a driver circuit during transition of states are provided. The driver circuit is operative in one of a high state, a low state and a tri-state based on the PWM input. The method includes receiving a tri-state command for transition from the high state to the tri-state. A PWM output signal is enabled to transition from a high logic value to a low logic value for driving the driver circuit from the high state to the low state upon receipt of the tri-state command. The PWM output signal is enabled to transition from the low logic value to a tri-state logic value for driving the driver circuit from the low state to the tri-state upon elapse of a threshold time delay. The PWM input to the driver circuit is based on the PWM output signal.
