ATS266 General Description
ATS266 is an integrated Hall sensor with output drivers designed for electronic commutation of brush-less 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 darlington 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 (B) is larger than operate point (Bop), DO turn on (low) and DOB turn off (high). The outputs state is latched prior to release point (Brp) coming. if B< Brp, DO turn off and DOB turn on. ATS266 is rated for operation over temperature range from -20oC to 85 oC and voltage range from 4.0V to 28V. The devices are available in low cost die forms or rugged 4 pin SIP packages.
