AH3761

AH3761 High sensitivity Hall effect latch sensor for

BLDC fan and motor commutations

Description

The AH3761 is a high sensitivity 

CMOS Halls effect latch sensor 

for single‐phase brushless DC 

(BLDC) fans and motor 

commutation applications.  

The AH3761 has an integrated 

band‐gap voltage regulator, 

Hall‐voltage transducer, 

amplifier, chopper stabilization, 

Schmitt trigger and open‐drain 

output.

With wide operating voltage 

The Diodes advantage

The AH3761 is a chopper stabilized, small and versatile Hall-effect latch

sensor for cooling fans and motor commutation applications

Wide operating voltage 3V to 28V

Supports wide range of system voltages 3.3V/5V/12V/24V

Chopper stabilized

and temperature range, 

AH3761 is a small versatile 

Hall‐effect latch devices that 

turns on with south magnetic 

field of sufficient strength and 

turns off with north magnetic 

field of sufficient strength. It 

retains the output state when 

magnetic field is removed

Extremely low switch-point drift

Superior temperature stability

Insensitive to physical stress

High drive capability with built in short-circuit limit

Output can sink up to 50mA

Easy interface to wide variety of electronic circuits

Safe operation against output short-circuit

magnetic field is removed.

The AH3761 is available in

SC59 and SIP3 packages. 

Applications

BLDC cooling fan and motor commutations

Reverse supply protection

Safe operation against reverse power/battery connection

Wide operating temperature range -40

°C to 125°C

Suitable also for industrial and other thermally demanding applications
