Dual Schottky Diode Bridge
FEATURES
DESCRIPTION
•
Monolithic Eight-Diode Array
•
Exceptional Efficiency
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.
•
Low Forward Voltage
•
Fast Recovery Time
•
High Peak Current
•
Small Size
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 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.
