A sensor system (10) configured to interface a gate supply (12) with a sensor (14) comprises the sensor (14) to detect a user (46), the gate supply (12) to provide power to an apparatus (16). The apparatus (16) comprises an input (28) connected to the gate supply (12) for receiving power from the gate supply (12), a circuitry (17) for boosting a level of the power received from the gate supply (12), and an output (26) connected to the sensor (14) for providing the boosted level of power to the sensor (14). The circuitry (17) comprises a NPN bipolar transistor (22) having a base (34), a collector (32) and an emitter (30). The circuitry further comprises a PNP bipolar transistor (24) having another base (39), another collector (38) and another emitter (36). The NPN bipolar transistor (22) is an input transistor (22). The PNP bipolar transistor (24) is the output transistor (24). The base (34) of the input transistor (22) is connected to the input (28) of the apparatus (16). The collector (38) of the output transistor (24) and the emitter (30) of the input transistor (22) are connected together to the output (26) of the apparatus (16). The emitter (36) of the output transistor (24) is connected to a supply voltage (18) and the collector (32) of the input transistor (22) is connected to the base (39) of the output transistor (24). |
