TC78H600FTG,EL

TC78H600FNG/FTG CD Integrated Circuit Silicon Monolithic 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. ALERT output pin 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. 2012-09-05 1TC78H600FNG/FTG Block Diagram STBY GND Vcc ALERT STANBY POR UVLO AO1 H-Bridge Pre H-Bridge A Drive A SELECT AO2 IN1A RSGNDARSGNDB IN2A Input Input PWMA circuit circuit IN1B ISD TSD VM ISD IN2B TSD PWMB OSC OSC BO1 H-Bridge Pre H-Bridge B Drive B BO2 Vref Vref RSGNDB 2012-09-05 2
