PIN CONNECTION
The NJM2670 is a general-purpose 60V dual H-bridge
drive IC. It consists of a pair of H-bridges, a thermal shut
down circuit and its alarm output. The alarm output can
detect application problems and the system reliability will be
significantly improved if monitored by Micro Processor.
Therefore, it is suitable for two-phase stepper moto
r
application driven by microprocessor.
