DESCRIPTION

This eight-diode array is designed for high-current, low duty-cycle applications
typical of flyback voltage clamping for inductive loads. The dual bridge connection
makes this device particularly applicable to bipolar driven stepper motors.

The use of Schottky diode technology features high efficiency through lowered for­ward voltage drop and decreased reverse recovery time.

This single monolithic chip is fabricated in both hermetic CERDIP and copper­leaded 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 desi gned 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.
