High-Frequency 100V-Rated Gate Driver From Diodes Incorporated Raises Power Efficiency While Saving Board Space
The DGD0579U’s 100V floating high-side driver provides greater flexibility for demanding high-power applications. Short propagation delays (typically 60ns) and delay matching (within 10ns) enable higher switching speeds and reduced dead-time, resulting in smaller, more efficient power system implementations.
Advanced MOSFET protection mechanisms are directly integrated into the device, improving system reliability, optimizing board space usage, and further reducing component count compared to traditional discrete solutions. These mechanisms include cross conduction prevention, so that the high-side and low-side MOSFETs are not on at the same time, and under-voltage lockout (UVLO) to address potential supply losses.
Featuring an enable pin for power management and ultra-low (<1μA) standby current, the DGD0579U contributes to prolonged battery running times. Compatible with control signals from microcontrollers and PWM controller ICs, the DGD0579U supports TTL and CMOS logic level inputs (down to 3.3V).
The DGD0579U gate driver is supplied in the compact W-DFN3030-10 package, with a 3mm x 3mm footprint and a 0.75mm profile height, and is available at
