The • Bootstrap Supply Voltage up to 118V DC floating high-side driver is capable of operating with supply voltages up to 100V. The “A” versions provide • Fast Propagation Times (25 ns Typical) a full 3A of gate drive while the “B” and “C” versions • Drives 1000 pF Load with 8 ns Rise and Fall provide 2A and 1A respectively. The outputs are Times independently controlled with CMOS input thresholds • Excellent Propagation Delay Matching (3 ns (LM5100A/B/C) or TTL input thresholds (LM5101A/B/C). An integrated high voltage diode is typical) provided to charge the high-side gate drive bootstrap • Supply Rail Under-voltage Lockout capacitor. A robust level shifter operates at high • Low Power Consumption speed while consuming low power and providing • Pin Compatible with HIP2100/HIP2101 clean level transitions from the control logic to the high-side gate driver. Under-voltage lockout is provided on both the low-side and the high-side TYPICAL APPLICATIONS power rails. These devices are available in the • Current Fed Push-pull Converters standard SOIC-8 pin, SO PowerPad-8 pin and the • Half and Full Bridge Power Converters WSON-10 pin packages. The LM5100C and LM5101C are also available in MSOP-PowerPad-8 • Synchronous Buck Converters package. The LM5101A is also available in WSON-8 • Two Switch Forward Power Converters pin package. • Forward with Active Clamp Converters Package • SOIC-8 • SO PowerPad-8 • WSON-8 (4 mm x 4 mm) • WSON-10 (4 mm x 4 mm) • MSOP-PowerPad-8 Simplified Block Diagram 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
