Description: The NJM2670 is a general-purpose 60V dual H-bridge driver. It’s basically just a pair of H-bridges, a thermal shut down circuit and its alarm output. The alarm output can detect application problems so if you’re monitoring it with a microcontroller you can keep from doing any real damage. It’s even suitable for two-phase stepper motors!


  • Wide Voltage Range (4V to 60V)
  • Wide Range of Current Control (5 to 1500mA)
  • Thermal Overload Protection
