Introduction

AI Translation

The UCC27211A device driver offers significant performance improvements over the UCC27201 MOSFET driver. Peak output source and sink currents are increased to 4A source and 4A sink, while pull-up and pull-down resistances are reduced to 0.9Ω, enabling large power MOSFETs to be driven with minimal switching losses during Miller plateau transitions. The input structure can directly handle -10 VDC, improving robustness and allowing direct interfacing with gate drive transformers without rectifier diodes. This input is independent of supply voltage, with a maximum rating of 20V. The switching node (HS pin) of the UCC27211A can handle voltages up to -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) add hysteresis, providing enhanced noise immunity at the interface with analog or digital PWM controllers. The low-side and high-side gate drivers are independently controlled, with matched turn-on and turn-off times to within 2ns. An integrated bootstrap diode rated at 120V eliminates the need for an external discrete diode. Both high-side and low-side drivers feature UVLO, providing symmetrical turn-on and turn-off behavior that forces the output low when the drive voltage falls below the specified threshold. The UCC27211A is available in an 8-pin SOIC (D), 8-pin VSON (DRM), and 8-pin SO-PowerPAD package.
