DGD0597FUQ High-Frequency High-Side and Low-Side Gate Driver
IMPORTANT NOTICE: THE DGD0597FUQ IS NOT RECOMMENDED FOR NEW DESIGNS. PLEASE CONTACT US.
Description
The DGD0597FUQ is a high-frequency, high-side and low-side gate driver capable of driving n-channel MOSFETs in a half-bridge configuration. The floating high-side driver is rated up to 40V and provides a 5V gate drive to the MOSFETs.
The DGD0597FUQ logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with MCUs. A UVLO (Under-Voltage Lockout) will protect ICs and MOSFETs with loss of supply.
Fast and well-matched propagation delays allow a higher switching frequency, enabling a smaller, more compact power switching design, using smaller associated components. The DGD0597FUQ is offered in the V-QFN3030-8 (Standard) package and operates over an extended -40°C to +125°C temperature range.
