LM5105
100V Half Bridge Gate Driver with Programmable
Dead-time
General Description
The LM5105 is a high voltage gate driver designed to drive
both the high side and low side N –Channel MOSFETs in a
synchronous buck or half bridge configuration. The floating
high-side driver is capable of working with rail voltages up to
100V. The single control input is compatible with TTL signal
levels and a single external resistor programs the switching
transition dead-time through tightly matched turn-on delay
circuits. A high voltage diode is provided to charge the high
side gate drive bootstrap capacitor. The robust level shift
technology operates at high speed while consuming low
power and provides clean output transitions. Under-voltage
lockout disables the gate driver when either the low side or
the bootstrapped high side supply voltage is below the op-
erating threshold. The LM5105 is offered in the thermally
enhanced 10-pin LLP plastic package.
