Single Phase Hall Effect Latch

ATS477

Features

General Description

- On-chip Hall sensor

ATS477 that integrates Hall sensor with output

drivers is designed for electrical commutation of

brush-less DC motor application. The device

includes on-chip Hall voltage generator for

magnetic sensing, the error amplifier that amplifies

the Hall voltage, a comparator that is to provide

switching hysteresis for noise rejection, the

bi-direction drivers for sinking and driving large

current load, and the frequency generator (FG) that

provides a signal proportional to rotation speed.

Internal bandgap regulator is used to provide

temperature compensated bias for internal circuits

and allows a wide operating supply voltage range.

Built-in protection circuit and output shunt Zener

diodes were applied for protecting output drivers

during operating.

- Bi-direction H type output drivers for single coil

- Internal bandgap regulator allows temperature

compensated operations and a wide operating

voltage range

- High output sinking capability up to 250mA

- Operating voltage: 3.5V~20V

- Low output switching current noise

- Build-in shunt Zener protection for output driver

- SOP-7L provide FG output pin

- Package: SIP-4L and SOP-7L

Applications

- Single-coil Brush-less DC Fan

- Single-coil Brush-less DC Motor

If a magnetic flux density is larger than threshold

Bop, DO is turned to sink and DOB is turned to

drive. The output state is held until a magnetic flux

density reversal falls below Brp causing DO to be

turned to drive and DOB turned to sink.

ATS477 is rated for operation over-temperature

range from -20 ^oC to 85 ^oC and voltage range from

3.5V to 20V. The devices are available in low cost

die forms or rugged SIP-4L and power SOP-7L

packages.
