UH266 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD LINEAR INTEGRATED CIRCUIT HIGH VOLTAGE HALL EFFECT LATCH - DESCRIPTION The UTC UH266 is a one-chip posed 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 plementary darlington open-collector drivers for sinking large current loads. An internal bandgap regulator is used to provide temperature pensated 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: 400m A(Continuous, 25°C) - Output protection Zener breakdown Vz=62V(Typ) - Reverse power protection - ORDERING INFORMATION Ordering Number UH266G-G04-K Package SIP-4 SIP-4 Packing Bulk - MARKING .unisonic..tw Copyright © 2016 Unisonic Technologies Co., Ltd 1 of 5 QW-R118-016.D - PIN DESCRIPTION PIN NO. 1 2 3 4 PIN NAME VCC DO DOB GND DESCRIPTION Positive Power Supply Output Pin Output Pin Ground - BLOCK DIAGRAM Regulator Over-Temperature Protection LINEAR INTEGRATED CIRCUIT Hall Plate Amplifier...
