LM5109ASD/NOPB

The LM5109ASD/NOPB is a half-bridge high-voltage Gate Driver 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 working with rail voltages up to 90V. The outputs are independently controlled with TTL compatible input thresholds. The robust level shift technology operates at high speed while consuming low power and providing clean level transitions from the control input logic to the high-side gate driver. Under-voltage lockout is provided on both the low-side and the high-side power rails.
