Single Output Hall Effect Latch

ATS177

Features

General Description

ATS177 is an integrated Hall effect latched sensor

designed for electronic commutation of brush-less

DC motor applications. The device includes an

on-chip Hall voltage generator for magnetic sensing,

a comparator that amplifies the Hall voltage, and a

schmitt trigger to provide switching hysteresis for

noise rejection, and open-collector output. An

internal bandgap regulator is used to provide

temperature compensated supply voltage for

internal circuits and allows a wide operating supply

range.

- 3.5V to 20V DC operation voltage

- Temperature compensation

- Wide operating voltage range

- Open-Collector pre-driver

- 25mA maximum sinking output current.

- Reverse polarity protection

- Package: SIP3, SOT23

Applications

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).

- Brush-less DC Motor

- Brush-less DC Fan

- Revolution counting

- Speed measurement
