LM5109BMAX Integrated Circuit Chip 1A Peak Half Bridge Gate Driver SOIC-8

LM5109BMAX Integrated Circuit Chip 1A Peak Half Bridge Gate Driver SOIC-8

Product Description Of LM5109BMAX

LM5109BMAX is a cost-effective, 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 90 V.

LM5109BMAX——The outputs are independently controlled with cost-effective TTL and CMOS-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. Undervoltage lockout is provided on both the low-side and the high-side power rails.

LM5109BMAX is available in the 8-pin SOIC and thermally-enhanced 8-pin WSON packages.
