Description

The G276P is an 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.

G276P is rated for operation over temperature range from -20к to 85к and voltage range from 3.5V to 20V. The devices

are available in low cost die forms or rugged 4 pin SIP packages.

Features

*On-chip Hall sensor IC with two different sensitivity and hysteresis settings for G276P

*Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range.

*High output sinking capability up to 300mA for driving large load.

*Lower current change rate reduces the peak output voltages during switching.

*Build in protection diode for chip reverse power connecting.

*Package: SIP-4L.
