AH3761

NPA Number 001 Announcement New Product 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  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. The AH3761 is available in SC59 and SIP3 packages.  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 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 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 Applications BLDC cooling fan and motor commutations cooling fan and motor commutations RPM monitor Position sensors www.diodes.com NPA Number 001 Announcement New Product AH3761 AH3761 High sensitivity Hall effect latch sensor for BLDC fan and motor commutations Vdd R 1 AH3761 2 3 Output GND Electrical characteristics Part Number Operating Voltage (V) Max output current (mA) Typical IC supply current (mA) Max Operating Point Bop Point Bop at 25°C (Gauss) Min Release Point Brp Point Brp at 25°C (Gauss) Operating Temperatur Temperatur e (°C) Package AH3761 3 to 28 50 4 60 -60 -40 to 125 *SIP3 **SC59 * SIP3 is through-hole pin compatible to TO-92 ** SC59 is pin compatible to landing patterns of SOT23 To find out more information: Product page: Datasheet: http://www.diodes.com/products/catalog/detail.php?item-id=5486 http://www.diodes.com/datasheets/AH3761.pdf www.diodes.com NPA Number 001 Announcement New Product AH3761 AH3761 High sensitivity Hall effect latch sensor for BLDC DC fan and motor commutations Product portfolio Part Number Operating Voltage (V) Average Output current (mA) Operating Point Bop (Gauss) Release Point Brp (Gauss) Operating Temperature (°C) Package AH173 AH175 AH1751 AH266 AH276Q AH342 AH373 AH375 ATS177 AH3761 3 to 20 3.5 to 20 3.5 to 20 4 to 28 3.5 to 20 4.5 to 28 2.5 to 20 2.5 to 20 3.5 to 20 3 to 28 25 25 50 400 400 3.4 to 7.4 25 25 25 50 15/60 5/80 15/60 5/80 5/70 10/70 10/50 5/70 40/120 5/60 5/60 5/70 5/60 -60/-15 -80/-5 -60/-15 -80/-5 -70/-5 -70/-10 -50/-10 -70/-5 -120/-40 -60/-5 -60/-5 -70/-5 -60/-5 -40 to 125 -40 to 150 -40 to 125 -20 to 85 -20 to 85 -40 to 125 -40 to 125 -40 to 125 -20 to 85 -40 to 125 SC59 SIP3 SC59 SIP-3L SIP3 SIP4 SIP4 SIP4-L SC59, SIP3 SC59, SIP3 SIP-3L SC59, SIP3 Ordering information Device Packaging (Note 2) SIP3 SIP3 SC59 Pack mark 3761 Y WW X 3761 Y WW X P8 Y W X Reel size Tape width NA NA 8mm Ammo box (Note 3) 4000 NA NA Quantity Bulk (Note 4) NA 1000 NA Reel NA NA 3000 AH3761-PG-A AH3761-PG-B AH3761-WG-7 Notes: 1.
