Integrated Circuit Hall Effect Sensor (AH4059) Controlling IC Magnetic Sensor

 
Features
Rated working voltage 4.5 V ~ 24 V, the limit voltages as low as 3.5 V;    
Operating temperature range: -55ºC ~ 150ºC;
 Rated output current (sink) : 300 mA, it can directy drive the coils of DC motor (Fan ).
Special design make the sensor owns imunity to logic race condition, short switch time and good switch sensitivity.
No mechanical contact, no spark, switch signal stability, no shaking moment, high reliability and safety;
Products meet the EU RoHS instruction 2011/65 / EU and REACH regulations 1907/2006 / EU requirements

Outline
AH4059 bipolar two ends complementary output switch type Hall Sensor, when the "S" pole faces the sensor's mark surface and is closed to sensor (B≥Bop),output terminal VO1 outputs low level, and the output terminal VO2 outputs high level; when the "N"pole faces senosor's mark surface and is closed to sensor (B≤Brp),output terminal VO1 outputs high level, the output terminal VO2 output low level. Stable hysteresis (Bh= Bop- Brp) ensures stable switch status, The magnetic and electric transfer characteristic curve of AH4059 is shown as the figure:

AH4059 Hall Sensor is a kind of bipolar field excitation two ends complementary output switch type Hall IC. Complementary output Hall sensor is particularly suitable for double coil DC motor, double coil DC fan, speed measurement and rotation control. The sensor chip intergrated bandgap reference voltage source, Hall voltage generator, signal amplifier, hysteresis controller, reverse voltage protection diode, and two way complementary output open collector output driver which sink current reaches 300mA and so on circuit unit. Excellent bandgap reference voltage source ensures the sensor can keep concordant sensitivity in a wide temperature range. Reverse voltage protection diode can avoid reverse power failure.
