1 / 5 page UNISONIC TECHNOLOGIES CO., LTD UH266 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 5 Copyright © 2013 Unisonic Technologies Co., Ltd QW-R118-016.A 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 SIP-4 1 ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free UH266L-G04-K UH266G-G04-K SIP-4 Bulk Note: xx: Output Voltage, refer to Marking Information. |
