Toshiba 2-channel H-bridge motor driver
Built-in regulator to drive internal circuits
Motor drive with single power supply


On the 22nd, Toshiba released the 'TC78H660FNG', a 2-channel H-bridge motor driver that controls brushed DC motors and stepping motors.
The TC78H660FNG leverages Toshiba's next-generation DMOS process to achieve a low on-resistance of 0.48Ω at a maximum rating of 18V/2.0A. This reduces heat generation compared to Toshiba's current market offerings.

It features a built-in regulator for driving internal circuits, enabling it to drive motors with a single power supply ranging from 2.5 to 16 V. Standby current consumption is less than 0.1 μA and it supports a 1.8 V low-voltage interface.

Additionally, it enables direct PWM control and constant current control without the need for a current sensing resistor. Safety features include overcurrent protection, overheating shutdown, undervoltage lockout, and flag output when overcurrent or overheating is detected.

The TC78H660FNG, which can be used in devices powered by 3.7V lithium-ion batteries, 5V USB, and 12V system devices, is available in a 5.0mm×6.4mm TSSOP16 package.
