Latch Type Hall Sensor AH4158
Rated working voltage 4.5 V ~ 24 V, the limit voltages as low as
Operating temperature range: -55℃ ~ 150℃;
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.
AH4158 Hall Sensor is a kind of unipolar 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..
