A6851 is an integrated Hall Effect Sensor (6851) 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).A6851 is rated 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.
