Introduction
The UCC27211A device driver is based on the widely popular UCC27201 MOSFET driver, but offers significant performance improvements by comparison.
Peak output source and sink currents have been increased to 4A source and 4A sink, and the source and sink resistances have been reduced to 0.9Ω, enabling high-power MOSFETs to be driven with minimal switching losses during Miller plateau transitions. The input structure can directly handle -10 VDC, improving robustness and enabling direct interfacing with gate drive transformers without the need for rectifier diodes. This input is independent of the supply voltage and has a maximum rating of 20V.
The switching node (HS pin) of the UCC27211A can handle voltages as low as -18V, protecting the high-side channel from negative voltages inherent to parasitic inductances and stray capacitances. The UCC27210A (pseudo-CMOS inputs) and UCC27211A (TTL inputs) have added hysteresis to provide enhanced noise immunity for interfacing with analog or digital PWM controllers.
The low-side and high-side gate drivers are independently controlled, with turn-on and turn-off matching of up to 2ns between each other.
An on-chip bootstrap diode rated at 120V eliminates the need for an external discrete diode. Both the high-side and low-side drivers feature UVLO, providing symmetrical turn-on and turn-off behavior and forcing the output low when the drive voltage falls below the specified threshold.
The UCC27211A is available in an 8-pin SOIC (D), an 8-pin VSON (DRM), and an 8-pin SO-PowerPAD package.
