Overview

POWER MANAGEMENT Description 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 max 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 circuit prevents shootthrough from Vin to GND in the main and synchronous MOSFET’s.
The Adaptive 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.
The high current drive capability (3A peak) allows fast switching, thus reducing switching losses at high (up to 1MHz) frequencies without overheating the driver.
The high voltage CMOS process allows operation from 5-25 Volts at top MOSFET drain, thus making SC1205 suitable for battery powered applications.
Connecting Enable pin (EN) to logic low shuts down both drives and reduces operating current to less than 10uA.
An 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).
An Internal temperature sensor shuts down all drives in the event of overtemperature.
SC1205 is fabricated utilizing Bi-CMOS technology for low quiescent current.
The SC1205 is offered in a standard SO-8 package.
Typical Application Circuit SC1205 High Speed Synchronous Power MOSFET Driver Features Fast rise and fall times (15ns typical with 3000pf load) 3 Amp 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 10µA supply current when EN is low Low cost Applications High Density sunchronous power supplies Motor Drives/Class-D amps/Half bridge drivers High frequency (to 1.
