TC78H600FNG/FTG
DUAL-BRIDGE DRIVER IC FOR DC MOTORS
The TC78H600FNG/FTG is a dual-bridge driver IC for DC motors which incorporates DMOS in output transistors.
DMOS output driver with low ON-resistance and PWM drive system are applied to realize high efficiency driving.
Features
Power supply voltage for motor: VM=15V (max)
Power supply voltage for control: Vcc=2.7V to 5.5V
(Operation range)
Output current: Iout 0.8A (max)
Output ON resistance: Ron=1.2(upper and lower sum)
Internal pull-down resistors on inputs: 200 k(typ.)
Built-in over current detection (ISD), thermal shutdown
(TSD) circuit, and under voltage lockout (UVLO) circuit.

Package: TC78H600FNG;SSOP20, TC78H600FTG; QFN24
Built-in cross conduction protection circuit
P-WQFN24-0404-0.50-004
* This product has a MOS structure and is sensitive to
Weight: SSOP20-P-225-0.65A: 0.09g(typ.)
electrostatic discharge. When handling this product,
P-WQFN24-0404-0.50-004: 0.03g(typ.)
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.
