AH337
Single Phase Hall Effect Switch
Features
General Description
- 4.2V to 28V DC operation voltage
- Temperature compensation
- Wide operating voltage range
- Open drain pre-driver
AH337 is an switched Hall-Effect IC which is for
contactless switching applications. The device
includes an on-chip Hall voltage generator for
magnetic sensing, an amplifier that amplifies the
Hall voltage, a schmitt trigger to provide switching
hysteresis for noise rejection, and an open-collector
output. The bandgap regulator allows a wide
operating voltage range.
- 25mA maximum sinking output current.
- Package: SIP3, SOT23
If a magnetic flux density larger than threshold Bop,
DO is turned on(low). The output state is held until
a magnetic flux density reversal falls below Brp
causing DO to be turned off (high).
Applications
- VCD/DVD loader, CD/DVD ROM
- Cover detector
- Speed measurement
- Home appliances
- Home safety
