The LM5107 is a low cost 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 100V. The outputs are independentlycontrolled with TTL compatible input thresholds. An integratedon chip high voltage diode is provided to charge thehigh side gate drive bootstrap capacitor. A robust level shiftertechnology 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 powerrails. The device is available in the SOIC-8 and the thermallyenhanced LLP-8 packages.
