100V, 3A, 2A or 1A half-bridge gate driver with 8V UVLO and TTL inputs | DDA | 8 | -40 to 125

The LM25101 high-voltage gate driver is designed to drive both the high-side and the

low-side N-Channel MOSFETs in a synchronous buck or a half-bridge configuration. The A version

provides 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 TTL input thresholds. 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 8-pin SOIC, 8-pin SO-PowerPAD, 8-pin WSON,

10-pin WSON, and 8-pin MSOP PowerPAD packages.
