SC1405 General Description

The SC1405 is a Dual-MOSFET Driver with an internal Overlap Protection Circuit to prevent shoot-through from V_IN to GND in the main switching and synchronous MOSFET's. Each driver is capable of driving a 3000pF load in 20ns rise/fall time and has ULTRAFAST propagation delay from input transition to the gate of the power FET's. The Overlap Protection circuit ensures that the second 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 to high is externally programmable via a capacitor for optimal reduction of switching losses at the operating frequency. The bottom FET may be disabled at light loads by keeping S_MOD low to trigger asynchronous operation, thus saving the bottom FET's gate drive current and inductor ripple current. An internal voltage reference allows threshold adjustment for an Output Over-Voltage protection circuitry, independent of the PWM feedback loop. 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). A CMOS output provides status indication of the 5V supply. A low enable input places the IC in stand-by mode thereby reducing supply current to less than 10A. SC1405 is offered in a high pitch (.025" lead spacing) TSSOP package.
