An electronic latch for a motor vehicle closure system with an electronic control circuit including a handle switch reading circuit for a two-pin handle switch and a method of operating the handle switch reading circuit are disclosed. The electronic control circuit includes a control unit. The handle switch reading circuit is controlled by the control unit for coupling with a handle switch subassembly. The handle switch reading circuit is adapted to supply an AC voltage to the handle switch subassembly and produce an output voltage waveform corresponding to the charging and discharging of a handle capacitor of the handle switch subassembly and in response to a handle switch of the handle switch subassembly being operated. The handle switch reading circuit determines a position of the handle switch and presence of faults in the handle switch reading circuit and the handle switch subassembly based on the output voltage waveform.

An electronic control circuit with a backup energy source subassembly for an e-latch assembly and a method of operating the backup energy source subassembly are disclosed. The electronic control circuit includes a control unit including a computing module and a memory for electrically coupling to a plurality of sensors and to a main power source. The backup energy source subassembly is electrically coupled to the control unit for providing electrical energy to the electronic control circuit in response to one of a failure and interruption of the main power source. An output module is electrically connected to the backup energy source subassembly and to the main power source for driving an actuation group. The backup energy source subassembly includes a backup low voltage source and a boost-buck converter configured to selectively supply voltage to and selectively amplify voltage from the backup low voltage source.
