LM5101ASD Typical application Circuitry

In a synchronous buck or half-bridge configuration, the LM5101ASD serves as a gate driver for high-voltage N-Channel MOSFETs on both the high-side and low-side. Its primary function is to facilitate the driving of these MOSFETs, enabling efficient power conversion in the desired power topology. Its purpose is to facilitate the driving of both the high-side and low-side MOSFETs in the power topology.

Key Features of LM5101ASD

1. High-Speed Operation: The LM5101ASD offers high-speed operation with typical delay times of 15ns and typical rise and fall times of 10ns.

2. Voltage Capabilities: It can tolerate high voltage swings up to 100V on its outputs, which allows for usage in high-voltage applications.

3. Independent Inputs: The chip has independent high-side and low-side inputs, providing flexibility in controlling the MOSFETs.

4. Protection Features: It has under-voltage lockout (UVLO) for both high-side and low-side channels.

Typical Applications for LM5101ASD

The LM5101ASD can be used in several applications, including synchronous buck converters, half-bridge converters, full-bridge converters, and motor drives.

Design Guide for LM5101ASD

An application of the LM5101ASD could be in a synchronous buck converter circuit. Here's how you might connect it:

1. VDD Pin (Pin 2): Connect this pin to a 10V power supply. This pin is the power supply input for the low-side driver.

2. HB Pin (Pin 6): The high-side driver's floating power supply is connected to this pin. Connect it to the output of a bootstrap diode and capacitor.

3. HS Pin (Pin 5): Put a wire between this pin and the high-side MOSFET's source. It is the return for the high-side gate driver.

4. HI and LI Pins (Pins 1 and 3): Connect these pins to your PWM signals. These serve as the high-side and low-side drivers' respective input pins.

5. HO and LO Pins (Pins 7 and 8): Connect these pins to the gates of the high-side and low-side N-Channel MOSFETs, respectively. These pins output the gate drive signals.

Design Considerations:

1. Bootstrap Circuit: The bootstrap circuit needs to be designed to provide sufficient voltage for the high-side driver.

2. Dead Time: Be cautious when using PWM signals to make sure there is sufficient dead time between the turning on and off of each MOSFET to prevent shoot-through.

3. PCB Layout: Minimize trace lengths to reduce parasitic inductance and ensure proper decoupling and thermal management.

4. Component Ratings: Ensure the components can handle the voltage and current requirements of your design.
