An electronic power apparatus includes a housing, a pair of input power pins, a pair of output power pins, power components arranged to modulate a supply of power from the input power pins to the output power pins, and a user-actuated input unit providing an analog signal indicative of a desired power output level of the output power pins. A control unit of the electronic power apparatus receives the analog signal from the user-actuated input unit. The control unit includes a controller to control a switching operation of the power components based on the analog signal, and an input detection unit to generate an ON/OFF signal to turn on the controller based detection of a prescribed change in the analog signal indicative of an initial actuation of the user-actuation unit.

1. An electronic power apparatus comprising: a pair of input power terminals;a pair of output power terminals;a plurality of power components arranged to modulate a supply of power from the input power terminals to the output power terminals;a user-actuated input unit providing an analog signal indicative of a desired power output level of the output power terminals; anda control unit receiving the analog signal from the user-actuated input unit, the control unit comprising: a controller configured to control a switching operation of the power components based on the analog signal; and an input detection unit configured to generate an ON/OFF signal to turn on the controller based on detection of a prescribed change in the analog signal indicative of an initial actuation of the user-actuation unit. 2. The electronic power apparatus of claim 1, wherein the control unit further comprises a regulator circuit configured to initiate supply of power to the controller upon activation of the ON/OFF signal. 3. The electronic power apparatus of claim 2, wherein the controller is configured to activate a control signal supplied to the regulator circuit after the controller is powered on and regulator circuit is configured to continue supplying power to the controller until the control signal is deactivated by the controller. 4. The electronic power apparatus of claim 3, wherein the regulator circuit comprises a semiconductor switch having a gate coupled to both the control signal and the ON/OFF signal and a bootstrap capacitor arranged between the ON/OFF signal and the gate of the semiconductor switch to enable the control signal to turn off the semiconductor switch irrespective of a state of the ON/OFF signal. 5. The electronic power apparatus of claim 1, wherein the analog signal is a variable-voltage signal and the input detection unit is configured to activate the ON/OFF signal upon detection of a voltage change of more than a predetermined amount in a voltage level of the analog signal. 6. The electronic power apparatus of claim 1, wherein the user-actuated input unit comprises: a variable-speed trigger coupled to a conductive wiper;a plurality of conductive pads including a plurality of first conductive pads respectively coupled to a plurality of resistors arranged in series with a first power input, and a second conductive pad coupled to a second power input; anda sense pad arranged adjacent the plurality of conductive pads and coupled to the analog signal, wherein the conductive wiper electrically connects the sense pad to the second conductive pad when the variable-speed trigger is depressed and electrically connects the sense pad to at least one of the plurality of first conductive pads when the trigger is actuated. 7. The electronic power apparatus of claim 1, wherein the power components are implemented as an H-bridge comprising four semiconductor switches, two of said semiconductor switches being synchronously modulated to control the supply of power to the output power terminals and the other two of said semiconductor switches being kept respectively on and off to control a direction of flow of current through the output power terminals. 8. The electronic power apparatus of claim 1, wherein no mechanical on/off switch is provided to cut off supply of power from the input power terminals to the plurality of power components. 9. The electronic power apparatus of claim 1, further comprising a housing encapsulating the plurality of power components and the control unit, a pair of input power pins coupled to the input power terminals, and a pair of output power pins coupled to the output power terminals.
