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 -20к to 100к 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.
