SGM48005
Zero Overshoot, Large Swing MOSFET Driver with Precision Dual-Rail Generation Circuit
TheSGM48005 is a high current MOSFET driver with a dual power rail generation circuit using a single inductor for getting both positive rail and negative rail. With its unique overshoot cancellation mechanism and its extended precision power rails, the SGM48005 drives the gate with no series damping resistor for sharp and clean rise and fall seen at the gate, which is important for high power design of switch mode power supplies running faster than a few hundred kHz. The adaptive overshoot cancellation allows placing the driver in a different location (temperature zone) from the power MOSFET’s, which simplifies circuit layout and cooling. The inverted input buffer is out of phase with the ground bouncing. Along with its current and voltage hysteresis, this assures high noise immunity and easy input signal coupling. The propagation delay of input low to output high is programmed with a resistor, for pairing switches in totem pole with no shooting through. The saturation voltage of power switch is sensed for over-current protection.
The SGM48005 is available in a Green TSSOP-14 package. It operates over an ambient temperature range of -40℃ to +125℃.
