AH174

Inverted Output Hall Effect Latch For High Temperature

Features

General Description

AH174 is a single-digital-output Hall-effect sensor

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 open-collector output pre-driver.

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 threshold Bop, the OUT pin turns off (High).

If B removed toward Brp, the OUT pin is latched

“off” state prior to B < Brp. When B < Brp, the OUT

pin go into “ on ” state.

- Bipolar Hall effect latch sensor

- 3.5V to 20V DC operation voltage

- Open collector pre-driver

- 25mA output sink current

- Chip power reverse-connection protection

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

- Package: SIP3, SOT23

Applications

- Rotor position sensing

- Current switch

- Encoder

- RPM detection
