ATS278

Two Phase Hall Effect Latch With FG Output

Features

General Description

- On-chip Hall plate

ATS278 is an integrated Hall sensor with two output

drivers and rotor speed output, typically designed

for electronic commutation of two-phase brush-less

DC fan applications.

- Operating voltage: 3.5V~20V

- Internal bandgap regulator allows temperature

compensated operations and a wide operating

voltage range

On-chip Hall sensor will generate Hall voltage due

to magnetics sensing. The amplifier will amplify the

Hall voltage. The Schmitt trigger determines

switching hysteresis and then control internal

driver’s on/off to sink load current. Meanwhile, An

internal bandgap regulator is used to provide stable

bais due to temperature-compensation. FG pin will

provide switching frequency of driver. Major feature

is to minimize the external components by

building-in FG output transistor.

- High output sinking capability up to 400mA for

driving large load

- Built-in protection diode only for chip reverse

power connecting

- Frequency Generation (FG) output

- Package: SIP-5L

Applications

If a magnetic flux density larger than threshold Bop,

DO is turned on (low) and DOB is turned off (high).

The output state is held until a magnetic flux density

reversal falls below Brp causing DO to be turned off

and DOB turned on.

- Dual-coil Brush-less DC Motor

- Dual-coil Brush-less DC Fan

- Revolution Counting

- Speed Measurement
