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

B<Brp, DO turn off and DOB turn on. UTC UH266 is rated for

operation over temperature range from -20°C to 85°C and voltage

range from 4V to 28V.
