DESCRIPTION  
FEATURES  
The SC1205 is a cost effective Dual MOSFET Driver  
designed for switching High and Low side Power  
MOSFETs. Each driver is capable of driving a  
3000pF load in 20ns rise/fall time and has a 20ns max  
propagation delay from input transition to the gate of  
the power FET’s. An internal Overlap Protection Cir-  
cuit prevents shoot-through from Vin to GND in the  
main switching and synchronous MOSFET’s. The  
Overlap Protection circuit ensures the Bottom FET  
does not turn on until the Top FET source has reached  
a voltage low enough to prevent cross-conduction.  
Fast rise and fall times (15ns typical with 3000pf  
load)  
2Amp peak drive current  
14ns max Propagation delay (BG going low)  
Adaptive Non-overlapping Gate Drives provide  
shoot-through protection  
Floating top drive switches up to 25V  
Under-Voltage lock-out  
Overtemperature protection  
Less than 10uA supply current when EN is low  
Low cost  
The high current drive capability (2A peak) allows fast  
switching, thus reducing switching losses at high  
(1MHz) PWM frequencies. The high voltage CMOS  
process allows operation from 5-25 Volts at top MOS-  
FET drain, thus making SC1205 suitable for battery  
powered applications. Connecting Enable pin (EN) to  
logic low shuts down both drives and reduces operat-  
ing current to less than 10uA.  
APPLICATIONS  
High Density sunchronous power supplies  
Motor Drives/Class-D amps/Half bridge drivers  
High frequency (to 1.2 MHz) operation allows use  
of small inductors and low cost caps in place of  
electrolytics  
Portable computers  
Battery powered applications  
An Under-Voltage-Lock-Out circuit is included to guar-  
antee 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). An Internal  
temperature sensor shuts down all drives in the event  
of overtemperature. SC1205 is fabricated utilizing  
CMOS technology for low quiescent current. The  
SC1205 is offered in a standard SO-8 package.
