NJM3771
Overview
The NJM3771 is a stepper motor driver, which circuit is especially developed for use in microstepping applications in conjunction with the matching dual DAC (Digital-to-Analog Converter) NJU39610. The NJM3771 contains a clock oscillator, which is common for both driver channels; a set of comparators and flip-flops imple menting the switching control; and two H-bridges with internal recirculation diodes.
- Dual chopper driver
- 650mA output current per channel
- Selectable slow / fast current decay for improved high- speed microstepping
- Specially matched to Dual DAC NJU39610
