1.2-A, 1.8-A 100-V half bridge gate driver with 8V-UVLO and programmable dead-time

The LM5106 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. 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 operating threshold. The LM5106 is offered in the VSSOP-10 or thermally enhanced 10-pin WSON plastic package.
