UC1610 UC2610 UC3610 Eight-Diode Schottky Diode Bridge, is designed for high-current, low duty-cycle applications, such as flyback voltage clamping inductive loads. Dual bridge connection makes this device particularly applicable to bipolar driven stepper motors. The use of Schottky diode technology features high efficiency through lowered for- ward voltage drop and decreased reverse recovery time. This single monolithic chip is fabricated in both hermetic CERDIP and copper- leaded plastic packages. The UC1610 in ceramic is designed for -55°C to +125°C environments but with reduced peak current capability. The UC2610 in plastic and ceramic is designed for -25°C to +125°C environments also with reduced peak current capability; while the UC3610 in plastic has higher current rating over a 0°C to +70°C temperature range.
This document describes the UC1610, UC2610, and UC3610, which are eight-diode arrays designed for high-current, low duty-cycle applications. These devices are particularly applicable to bipolar driven stepper motors and utilize Schottky diode technology for high efficiency. They are available in hermetic CERDIP and copper-leaded plastic packages.
