A6852S/N

SINGLE OUTPUT HALL EFFECT SWITCH IC

ꢀ FEATURES

1) Wide range of supply voltage:3.5V to 28V.

2) Internal bandgap regulator allows temperature

compensated operations and a wide operating

voltage range.

4) TTL and MOS ICs directly drivable by output.

5) Build in protection diode for chip reverse power

connecting.

6) Package: SIP-3.

3) High sensitivity with a small magnet.

ꢀ GENERAL DESCRIPTION

A6852S/N is an integrated Hall effect switch sensor

with output pull-high resistor driver designed for

electronic commutation of brushless DC motor

applications and contactless switches. 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 output driver with

pull-high resistor. An internal bandgap regulator is

used to provide temperature compensated supply

voltage for internal circuits and allows a wide

operating supply range.

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).

A6852S/N is srated for operation over temperature

range from -20 ^oC to 100 ^oC and voltage range from

3.5V to 28V. The devices are available in low cost

die forms or rugged 3 pin SIP packages.

ꢀ APPLICATIONS

1) DC Motor

2) DC Fan

3) Position Sensors

4) Rotation Sensors

5) Revolution Counting

6) Speed Measurement

7) Keyboard Switches

8) Microswitches
