The UTC UH266 is a one-chip composed of Hall sensor and output coil drivers, applied to two-phase brush-less DC motor. The device includes an on-chip Hall plate for magnetic sensing, a amplifier for Hall voltage, and a Schmitt trigger to provide switching hysteresis, and complementary darlington open-collector drivers for sinking large current loads. An inte.
