Single Output
Hall Effect Switch IC
Description
The SH6853 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).
SH6853 is rated for operation over temperature range from -40^oC
to 150^oC and voltage range from 3.5V to 28V. The devices are
available in low cost die forms or rugged 3 pin SIP packages.
