AH373

Internal Pull-up Hall Effect Latch

Features

General Description

- Bipolar Hall effect latch sensor

- 2.2V to 20V DC operation voltage

- Built-in pull-up resistor

AH373 is a single-digital-output Hall-effect sensor

with pull-up resistor for high temperature operation.

The device includes an on-chip Hall voltage

generator for magnetic sensing, an amplifier to

amplify Hall voltage, and a comparator to provide

switching hysteresis for noise rejection, and an

output driver with a pull-up resistor (Rpu). An

internal bandgap regulator is used to provide

temperature compensated supply voltage for

internal circuits and allows a wide operating supply

range. While the magnetic flux density (B) is larger

than operate point (Bop), the OUT pin turns on

(low). If B moves toward release point (Brp), the

OUT pin is latched “on” state prior to B < Brp. When

B < Brp, the OUT pin go into “ off ” state.

- 25mA output sink current

- Operating temperature: −40°C ~ +125°C

- Package: SIP3, SOT23

Applications

- Rotor position sensing

- Current switch

- Encoder

- RPM detection
