SC1405B  
High Speed Synchronous Power  
MOSFET Smart Driver with 7V Drive  
POWER MANAGEMENT  
Features  
Description  
The SC1405B is a Dual-MOSFET Driver with an internal  
Overlap Protection Circuit to prevent shoot-through. Each  
driver is capable of driving a 3000pF load in 15ns rise/  
fall time and has ULTRA-LOW propagation delay from in-  
put transition to the gate of the power FET’s. The Over-  
lap Protection circuit ensures that the synchronous FET  
does not turn on until the top FET source has reached a  
voltage low enough to prevent shoot-through. The delay  
between the bottom gate going low to the top gate  
transitioning high is externally programmable via a ca-  
pacitor for optimal reduction of switching losses at the  
operating frequency. The bottom FET may be disabled at  
light loads by keeping S_MOD low to trigger asynchro-  
nous operation, thus saving the bottom FET’s gate drive  
current and inductor ripple current. An internal voltage  
reference allows threshold adjustment for an Output  
Over-Voltage protection circuitry, independent of the PWM  
feedback loop. Under-Voltage-Lock-Out circuit is included  
to guarantee that both driver outputs are low when the  
5V logic level is less than or equal to 4.4V (typ) at supply  
ramp up (4.35V at supply ramp down). A CMOS output  
provides status indication of the 5V supply. A low enable  
input places the IC in stand-by mode thereby reducing  
supply current to less than 10µA. SC1405B is offered in  
a high pitch (.025” lead spacing) TSSOP package.  
u Fast rise and fall times (15ns with 3000pf load)  
u 14ns max. Propagation delay (BG going with low)  
u Adaptive/programmable shoot-through protection  
u 7V supply operation for lower Rds_on  
u Wide input voltage range (4.5-25V)  
u Programmable delay between MOSFET’s  
u Power saving asynchronous mode control  
u Output overvoltage protection/overtemp shutdown  
u Under-Voltage lock-out and power ready signal  
u Less than 10µA stand-by current (EN=low)  
u Power ready output signal  
u Improved drive version of SC1405TS  
u High frequency (to 1.2MHz) operation allows use of  
small inductors and low cost caps in place of  
electrolytics  
Applications  
u High Density/Fast transient power supplies  
u Motor Drives/Class-D amps  
u High efficiency portable computers
