SH6853

Single Output

Hall Effect Switch IC

Description

The SH

6853 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).

SH

6853 is rated for operation over temperature range from -40 C

to 1

50 C and voltage range from 3.5V to 28V. The devices are

available in low cost die forms or rugged 3 pin SIP packages.
