G6853

ISSUED DATE :2005/11/07 REVISED DATE : G6853 Description Single Output Hall Effect Switch IC The G6853 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). The G6853 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. * W ide range of supply voltage:3.5V to 28V. * Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range. * High sensitivity with a small magnet. * TTL and MOS ICs directly drivable by output. * Build in protection diode for chip reverse power connecting.
