资 源 简 介
The LM5105 is a high voltage gate driver designed to driveboth the high side and low side N –Channel MOSFETs in asynchronous buck or half bridge configuraTIon. The floaTInghigh-side driver is capable of working with rail voltages up to100V. The single control input is compaTIble with TTL signallevels and a single external resistor programs the switchingtransiTIon dead-time through tightly matched turn-on delaycircuits. A high voltage diode is provided to charge the highside gate drive bootstrap capacitor. The robust level shifttechnology operates at high speed while consuming lowpower and provides clean output transitions. Under-voltagelockout disables the gate driver when either the low side orthe bootstrapped high side supply voltage is below the operatingthreshold. The LM5105 is offered in the thermallyenhanced 10-pin LLP plastic package.
