AH173
Internal Pull-up Hall Effect Latch For High Temperature
Features
General Description
- Bipolar Hall effect latch sensor
- 3V to 20V DC operation voltage
- Built-in pull-up resistor
AH173 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
