SC1405D - High Speed Synchronous Power MOSFET Smart Driver

General Description

The SC1405D 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 input transition to the gate of the power FETs.

Key Features

  • ‹ Fast rise and fall times (15ns withPRELIMINARY 3000pf load) ‹ 14ns max. Propagation delay (BG going with low) ‹ Adaptive and programmable shoot-through protection ‹ Adaptive overvoltage protection ‹ Wide input voltage range (4.5V - 25V) ‹ Programmable delay between FETs ‹ Power saving asynchronous mode control ‹ Output overvoltage protection/overtemp shutdown ‹ Under-Voltage lock-out and power ready signal ‹ Less than 10µA stand-by current (EN=low) ‹ Power ready output signal ‹ High frequency.

High Speed Synchronous Power www.DataSheet4U.com MOSFET Smart Driver POWER MANAGEMENT Description The SC1405D 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 input transition to the gate of the power FETs. Adaptive Overlap 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 capacitor to minimize dead time.
