High Speed Synchronous Power MOS.ET Smart Driver
POWER MANAGEMENT Description
The SC1405CTS is a Dual-MOS.ET Driver with an internal Overlap Protection Circuit to prevent shoot-through. Each driver is capable of driving a 3000p. load in 15ns rise/fall time and has ULTRA-LOW propagation delay from input transition to the gate of the power .ETs. Adaptive Overlap Protection circuit ensures that the synchronous .ET does not turn on until the top .ET 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. The bottom .ET may be disabled at light loads by keeping S_MOD low to trigger asynchronous operation, thus saving the bottom .
