Abstract: Push-pull half-bridge magnetoresistive switch, comprising two magnetic sensor chips, each magnetic sensor chip having a magnetic induction resistor and a magnetic induction resistor electrical connection pad. The two magnetic sensor chips are electrically interconnected and have opposite and parallel directions of induction, thus forming the push-pull half-bridge circuit. The magnetic induction resistor comprises one or a plurality of magnetoresistive elements connected in series. The magnetic induction resistor pads are located at adjacent edges of the magnetic sensor chips, and each pad may accommodate the welding of at least two bonding wires. The magnetoresistive switch may improve the sensitivity of a sensor, and decrease output voltage deviation and output voltage temperature drift, which is beneficial for decreasing the volume and increasing the performance of the switch sensor.
