Peak output pull-up and pull-down current has been increased to 4-A source and 4-A sink, and pull-up and pull-down resistance have been reduced to 0.9 Ω, thereby allowing for driving large power MOSFETs with minimized switching losses during the transition through the Miller Plateau of the MOSFET. The input structure is now able to directly handle –10 VDC, which increases robustness and also allows direct interface to gate-drive transformers without using rectification diodes. The inputs are also independent of supply voltage and have a maximum rating of 20-V. 1 • • • • • • • • • • • • Drives Two N-Channel MOSFETs in High-Side and Low-Side Configuration With Independent Inputs Maximum Boot Voltage 120-V DC 4-A Sink, 4-A Source Output Currents 0.9-Ω Pullup and Pulldown Resistance Input Pins Can Tolerate –10 V to 20 V and Are Independent of Supply Voltage Range TTL or Pseudo-CMOS Compatible Input Versions 8-V to 17-V VDD Operating Range, (20-V Absolute Maximum) 7.2-ns Rise and 5.5-ns Fall Time With 1000-pF Load Fast Propagation Delay Times (18 ns Typical) 2-ns Delay Matching Symmetrical Undervoltage Lockout for High-Side and Low-Side Driver All Industry Standard Packages Available (SOIC8, PowerPAD™ SOIC-8, 4-mm × 4-mm SON-8 and 4-mm × 4-mm SON-10) Specified from –40 to 140 °C Device Information(1) PART NUMBER UCC27210, UCC27211 PACKAGE BODY SIZE (NOM) SOIC (8) 4.90 mm × 3.91 mm PowerPAD (8) 4.89 mm × 3.90 mm WSON (10) 4.00 mm × 4.00 mm VSON (8) (1) For all available packages, see the orderable addendum at the end of the datasheet. 2 Applications • • • • • • • Power Supplies for Telecom, Datacom, and Merchant Half-Bridge and Full-Bridge Converters Push-Pull Converters High-Voltage Synchronous-Buck Converters Two-Switch Forward Converters Active-Clamp Forward Converters Class-D Audio Amplifiers space Typical Application: UCC27210 +12V Typical Application: UCC27211 +12V +100V +100V VDD SECONDARY SIDE CIRCUIT VDD HB HB DRIVE HI LI CONTROL PWM CONTROLLER PWM CONTROLLER HO LI CONTROL HI DRIVE HI HI SECONDARY SIDE CIRCUIT HO HS DRIVE LO HS LO UCC27211 DRIVE LO LO VSS +12V UCC27210 VDD +100V VSS HB HI LI CONTROL ISOLATION AND FEEDBACK DRIVE HI HO HS DRIVE LO LO UCC27211 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
