com 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.
* Wide 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.
