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
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.
 FEATURES
* Operating voltage: 4V~28V
* Output current: 400mA(Continuous, 25°C)
* Output protection Zener breakdown Vz=62V(Typ)
* Reverse power protection
