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
