G276P
Complementary Output Hall Effect Latched Sink Driver IC
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 -20 to 85 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.
