AH266 Datasheet | Anachip

High Voltage Hall Effect Latch Features - On-chip Hall plate - Operating voltage: 4V~28V - Output current: 400m A(Continuous, 25o C) - Reverse protection diode only for chip reverse power connecting (Note) - Output protection Zener breakdown Vz=62V(Typ) - Package: SIP-4L (Note) Protection diode only exists at power pin(1,4) output, not including pin (2,3). General Description AH266 is an integrated Hall sensor with output drivers designed for electronic mutation of brush-less 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 darlington 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 (B) is larger than operate point (Bop), DO turn on (low) and DOB turn off (high). The outputs state is latched prior to reach release point (Brp). if B< Brp, DO turn off and DOB turn on. ATS266 is rated for operation over temperature range from -20o C to 85 o C and voltage range from 4V to 28V. The devices are available in low cost die forms or rugged 4 pin SIP packages.
