Low Power magnetic sensor

Introduction

AH469 is designed and produced using CMOS technology. It is a bipolar Hall switch chip with low power consumption and high sensitivity. 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 2.7-5.5V.

AH469 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.
