General Description
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. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.

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

Application
- Dual-coil Brush-less DC Motor
- Dual-coil Brush-less DC Fan
- Revolution Counting
- Speed Measurement
