The LM5105SD 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 voltage 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 operating threshold.
