Complementary Output Hall Effect Latched Sink Driver

A277 are integrated Hall Sensors with output drivers designed for electronic commutation 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 rejection, 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. A277 are rated for operation over temperature range from -20 o C to 85 o C and voltage range from 3.5V to 20V. The devices are available in low cost die forms or rugged 4 pin SIP packages. By Unkown
