VEHICLE DOOR LATCH
1. Vehicle door latch (1) for a motor vehicle (2) and configured to receive a main supply voltage (Vbatt) from a main power source (8) of the motor vehicle (2) during a normal operating condition, comprisinga supercapacitor group (3) configured to store energy during the normal operating condition and to provide a backup supply voltage (Vsc) during a failure operating condition different from the normal operating condition,an electric motor (4) configured for actuating the Vehicle door latch (1) based on the main supply voltage (Vbatt) during the normal operating condition and on the backup supply voltage (Vsc) during the failure operating condition, anda four-quadrant controller (5) comprising four switches, whereby each two switches form a series circuit with the electric motor (4) connected to an intermediate point between the two switches and the two series circuits are connected in parallel, wherebyduring the failure operating condition the four-quadrant controller (5) is operated with the backup supply voltage (Vsc).
