 Rated working voltage 2.4V ~ 5.5V,
 Work under Omnipolar, the excitation field
regardless of N or S pole, high magnetic
sensitivity, highly symmetric of positive
and negative magnetic switching points;
 Built-in dynamic offset voltage
compensation circuit, high temperature
stability, small drift switching point,
resistance to mechanical stress and thermal
stress;
 Ultra small power consumption, it’s only
8μW when the power supply is 2.75V ;
 Immune to ESD which is greater than 5kV
(body static mode, Human-Body Model,
HBM);
