Description
The SH236 is an integrated Hall effect latched sensor with
output pull-high resistor driver designed for electronic co-
mmutation of brushless DC motor applications. 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 re-
jection, and complementary open-collector drivers for sinking
large current loads. 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)
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.SH236 is rated for operation over
temperature range from -20oC to 85oC and voltage range from
3.5V to 20V. The devices are available in low cost die forms or
rugged 4 pin SIP packages.
