Introduction

AH463 is designed and produced using CMOS technology. It is a south pole and north pole sensitive low-power omnipolar  Hall  effect switch.  The  device  integrates  a  voltage  regulator,  a  Hall  voltage generator, a small signal amplifier, a chopper regulator, and schmitt-trigger and push-pull output. The sensor has the characteristics of good temperature stability, strong stress resistance and high sensitivity, and its operating voltage is 2.5-5.5V.

AH463 provides TO-92S in-line package and SOT23-3L package. Both packages meet RoHS

environmental protection standards.

Limit parameters

The limit parameter is the limit value when the chip is applied. Exceeding the limit value may damage the chip. Although the function of the chip is not necessarily damaged when the limit parameter is exceeded, if the limit value is exceeded within a certain period of time, the reliability of the chip may be affected.
