SC1405B

High Speed Synchronous Power

MOSFET Smart Driver with 7V Drive

POWER MANAGEMENT

Features

Description

The SC1405B 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 in-

put transition to the gate of the power FETs. The Over-

lap 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 ca-

pacitor 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 asynchro-

nous operation, thus saving the bottom FETs 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 10µA. SC1405B is offered in

a high pitch (.025 lead spacing) TSSOP package.

u Fast rise and fall times (15ns with 3000pf load)

u 14ns max. Propagation delay (BG going with low)

u Adaptive/programmable shoot-through protection

u 7V supply operation for lower Rds_on

u Wide input voltage range (4.5-25V)

u Programmable delay between MOSFETs

u Power saving asynchronous mode control

u Output overvoltage protection/overtemp shutdown

u Under-Voltage lock-out and power ready signal

u Less than 10µA stand-by current (EN=low)

u Power ready output signal

u Improved drive version of SC1405TS

u High frequency (to 1.2MHz) operation allows use of

small inductors and low cost caps in place of

electrolytics

Applications

u High Density/Fast transient power supplies

u Motor Drives/Class-D amps

u High efficiency portable computers
