The floating high-side driver is capable of operating with supply voltages up to 100 V.
The A versions provide a full 3-A of gate drive, while the B and C versions provide 2 A and 1 A, 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.
Undervoltage lockout is provided on both the low-side and the high-side power rails.
These devices are available in the standard SOIC-8 pin, SO PowerPAD-8 pin, and the WSON-10 pin packages.
The LM5100C and LM5101C are also available in MSOP-PowerPAD-8 package.
The LM5101A is also available in WSON-8 pin package.
