LM5104M Datasheet PDF - TI

The LM5104M is a high voltage half-bridge Gate Driver with adaptive delay, designed to drive both the high-side and the low-side N-channel MOSFETs in a synchronous buck configuration. The floating high-side driver can work with supply voltages up to 100V. The high-side and low-side gate drivers are controlled from a single input. Each change in state is controlled in an adaptive manner to prevent shoot-through issues. In addition to the adaptive transition timing, an additional delay time can be added, proportional to an external setting resistor. An integrated high-voltage diode is provided to charge high-side gate drive bootstrap capacitor. A robust level shifter operates at high speed while consuming low power and providing clean level transitions from the control logic to the high-side gate driver. Under-voltage lockout is provided on both the low-side and the high-side power rails.

● Drives both a high-side and low-side N-channel MOSFET

● Adaptive rising and falling edges with programmable

● Additional delay

● Single input control

● 25ns Typical fast turnoff propagation delay

● Supply rail under-voltage lockout

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
