G276P Datasheet | GTM

.. ISSUED DATE :2005/11/24 REVISED DATE : Description plementary Output Hall Effect Latched Sink Driver IC The G276P is an integrated Hall sensors with output drivers designed for electronic mutation of brushless DC motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a parator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and plementary open-collector drivers for sinking large current loads. An internal bandgap regulator is used to provide temperature pensated 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 are available in low cost die forms or rugged 4 pin SIP packages. to 85 and voltage range from 3.5V to 20V. The devices Features - On-chip Hall sensor IC with two different sensitivity and hysteresis settings for G276P - Internal bandgap regulator allows temperature pensated operations and a wide operating voltage range. - High output sinking capability up to 300m A 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.
