DESCRIPTION
The SC1205 is a cost effective Dual MOSFET Driver
designed for switching High and Low side Power
MOSFETs. Each driver is capable of driving a
3000pF load in 20ns rise/fall time and has a 20ns max
propagation delay from input transition to the gate of
the power FET’s. An internal Overlap Protection Cir-
cuit prevents shoot-through from Vin
to GND in the
main switching and synchronous MOSFET’s. The
Overlap Protection circuit ensures the Bottom FET
does not turn on until the Top FET source has reached
a voltage low enough to prevent cross-conduction.
The high current drive capability (2A peak) allows fast
switching, thus reducing switching losses at high
(1MHz) PWM frequencies. The high voltage CMOS
process allows operation from 5-25 Volts at top MOS-
FET drain, thus making SC1205 suitable for battery
powered applications. Connecting Enable pin (EN) to
logic low shuts down both drives and reduces operat-
ing current to less than 10uA.
An Under-Voltage-Lock-Out circuit is included to guar-
antee 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). An Internal
temperature sensor shuts down all drives in the event
of overtemperature. SC1205 is fabricated utilizing
CMOS technology for low quiescent current. The
SC1205 is offered in a standard SO-8 package.
