  • Power supply voltage for motor: VM=18 V (max)
  • Power supply voltage for control: VCC=6 V (max)
  • Output current: Iout=2.1 A (max)
  • Output ON resistance: Ron(upper and lower sum)=0.4 Ω (typ.)

Single H-bridge IC with a 2.1 A rating and a low on-resistance of 0.4 Ω for DC brushed motors and stepping motors used in mobile battery-drive equipment, home appliances, housing and facility equipment. The TC78H630FNG requires a logic power supply in the range of 2.7 to 5.5 V and can accept motor drive voltages in the range 2.5 to 15 V. In standby mode the current consumption is approximately 1 μA (max.). The maximum output voltage is 18 V. This new device is suitable for a wide range of applications.
