TC78H610FNG
TOSHIBA CDMOS Integrated Circuit Silicon Monolithic
TC78H610FNG
DUAL H-BRIDGE DRIVER IC
The TC78H610FNG is a dual H-bridge driver IC for DC motors
which incorporates DMOS in output transistors.
The TC78H610FNG is capable of driving 2 DC brushed motors or 1
stepping motor.

This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product,
ensure that the environment is protected against electrostatic discharge by using an earth strap, a conductive
mat and an ionizer. Ensure also that the ambient temperature and relative humidity are maintained at
reasonable levels.
*The IC should be installed correctly. Otherwise, the IC or peripheral parts and devices may be degraded or
permanently damaged.

The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must not be
exceeded during operation, even for an instant.
If any of these ratings are exceeded during operation, the electrical characteristics of the device may be irreparably
altered, in which case the reliability and lifetime of the device can no longer be guaranteed.
Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in other
equipment. Applications using the device should be designed so that no absolute maximum ratings will ever be
exceeded under any operating condition.

Maximum current is limited by power dissipation. It depends on the ambient temperature, excitation mode, and heat
radiation of the board.

Note 1: A power supply capacitor should be connected as close as possible to the IC.
Note 2: Please set “IN1 and IN2” or “/STBY” as “L” at the time of power supply ON and OFF. If power supply ON and
OFF is carried out in the state of H setup, unexpected current may be flown in the output pin depending on the
situation.
