SINGLE PHASE HALL EFFECT SWITCH
Description
AH337 is a unipolar Hall-
Effect sensor for contactless switching
applications. The device includes an on-
chip Hall voltage generator
for magnetic sensing, an amplifier that amplifies the Hall voltage, a
Schmi
tt trigger to provide switching hysteresis for noise rejection, and
an open-collector output. The band-
gap regulator allows a wide
operating voltage range.
When the magnetic flux density (B) is larger than operate point (Bop
),
output is switched on (OUT p
in is pulled low). The output state is held
on until a magnetic flux density falls below Brp. When B
is less than
Brp, the output is switched off.
The AH337 is available in SIP-3 (Ammo Pack), SIP-3 (Bulk Pack)
and
SC59 packages.
Features
• Unipolar Hall-Effect Sensor
• 4.2V to 28V DC Operating Voltage
• Temperature Compensation
• Open Drain Pre-Driver
• 25mA Maximum Output Sink Current
• Operating Temperature: -40°C to +125°C
• SIP-3 (Ammo Pack), SIP-3 (Bulk Pack) and SC59 Packages
(SC59 Is Commonly Known as SOT23 in Asia)
• Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
• Halogen and Antimony Free. “Green” Device (Note 3)

Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.
2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and
Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
