LM5109
Description
The LM5109 is a low cost 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 100V. The outputs are independently controlled with TTL patible input thresholds. A robust level shifter 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. The device is available in the SOIC-8 and the thermally enhanced LLP-8 packages. n n n n n n n Bootstrap supply voltage to 118V DC Fast propagation times (27 ns typical) Drives 1000 p F load with 15ns rise and fall times Excellent propagation delay matching (2 ns typical) Supply rail under-voltage lockout Low power consumption Pin patible with ISL6700
