Anachip AH266

AH266 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. The outputs state is latched prior to reach release point (Brp).

FEATURES

- On-chip Hall plate - Operating voltage: 4V~28V - Output current: 400mA(Continuous, 25oC) - 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

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). 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 4V to 28V. The devices are available in low cost die forms or rugged 4 pin SIP packages. Application - Dual-coil Brush-less DC Motor - Dual-coil Brush-less DC Fan - Revolution Counting - Speed Measurement Pin Assignment 4. GND 3. DOB 2. DO 1. VCC Pin Config...
