General Description

The LM5100A/B/C and LM5101A/B/C High Voltage Gate Drivers are designed to drive both the high-side and the low-side N-Channel MOSFETs in a synchronous buck or a half-bridge configuration. The floating high-side driver is capable of operating with supply voltages up to 100V. The “A” versions provide a full 3A of gate drive while the “B” and “C” versions provide 2A and 1A respectively. The outputs are independently controlled with CMOS input thresholds (LM5100A/B/C) or TTL input thresholds (LM5101A/B/C). An integrated high voltage diode is provided to charge the high-side gate drive bootstrap capacitor. A robust level shifter operates at high speed while consuming low power and providing 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 power rails. These devices are available in the standard SOIC-8 pin, PSOP-8 pin and the LLP-10 pin packages. The LM5100C and LM5101C are also available in eMSOP-8 package.
