G266
Complementary Output Hall Effect Latched Sink Driver IC
Description
The G266 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.
G266 is rated for operation over temperature range from -20 to 100 and voltage range from 3.5V to 28V. 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 G266
*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.
