资 源 简 介
The LM5109B is a cost effecTIve, high voltage gate driver designedto drive both the high-side and the low-side N-ChannelMOSFETs in a synchronous buck or a half bridge configuraTIon.The floaTIng high-side driver is capable of working withrail voltages up to 90V. The outputs are independently controlledwith TTL compaTIble input thresholds. The robust levelshift technology operates at high speed while consuming lowpower and providing clean level transitions from the controlinput logic to the high-side gate driver. Under-voltage lockoutis provided on both the low-side and the high-side power rails.The device is available in the SOIC-8 and the thermally enhancedLLP-8 packages.
