UH266

UNISONIC TECHNOLOGIES CO., LTD UH266 LINEAR INTEGRATED CIRCUIT HIGH VOLTAGE HALL EFFECT LATCH  DESCRIPTION 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 internal bandgap regulator is used to provide temperature compensated supply voltage and allows a wide operating range. If B>Bop, DO turn on (low) and DOB turn off (high). The outputs state is latched prior to reach release point (Brp). if BRegulator Over-Temperature Protection LINEAR INTEGRATED CIRCUIT DO Hall Plate Amplifier Schmitt Trigger Temperature Compensation Output ...
