Texas Instruments LM510x 100V MOSFET 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 can operate 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 Texas Instruments LM510x 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.
