SC1205 - HIGH SPEED SYNCHRONOUS POWER MOSFET DRIVER

General 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 max rise/fall time and has a 20ns max propagation delay from input transition to the gate of the power FET’s.

Key Features

  • ‹ Fast rise and fall times (15ns typical with 3000pf load) ‹ 3 Amp peak drive current ‹ 14ns max Propagation delay (BG going low) ‹ Adaptive Non-overlapping Gate Drives provide shoot-through protection ‹ Floating top drive switches up to 25V ‹ Under-Voltage lock-out ‹ Overtemperature protection ‹ Less than 10µA supply current when EN is low ‹ Low cost.

POWER MANAGEMENT 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 max 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 circuit prevents shootthrough from Vin to GND in the main and synchronous MOSFET’s. The Adaptive 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 (3A peak) allows fast switching, thus reducing switching losses at high (up to 1MHz) frequencies without overheating the driver.
