Semtech SC1405D
High-Speed Synchronous Power MOSFET Smart Driver
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.
Overview
Features
- Fast rise and fall times (15ns with 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 (to 1.2MHz) operation allows use of small inductors and low cost caps in place of electrolytics
- TSSOP-14 package
Applications
- High-density/fast-transient microprocessor power supplies
- Motor drives/class-D amps
- High-efficiency portable computers
Packaging
