Introducing the LM5100M High Voltage Gate Driver from Texas Instruments

The LM5100M is a high-performance gate driver designed to drive both the high-side and low-side N-Channel MOSFETs in a synchronous buck or half-bridge configuration. With its advanced features and robust design, the LM5100M is an ideal choice for a wide range of applications, including motor control, power supplies, and power conversion systems.

Key Features of the LM5100M:

• High-Voltage Capability: The LM5100M is capable of handling voltages up to 100V, making it suitable for high-voltage power applications.
• High Drive Current: With a peak output current of 1.5A for the high-side and 2.5A for the low-side, this gate driver can efficiently switch power MOSFETs at high frequencies.
• Independent Inputs: Separate inputs for high-side and low-side gates provide design flexibility and the ability to implement advanced control schemes.
• Bootstrap Diode: An integrated bootstrap diode simplifies the circuit design and reduces external component count.
• Under-Voltage Lockout (UVLO): Both high-side and low-side drivers feature UVLO to ensure the gates are only driven when there is sufficient voltage.
• Fast Propagation Delays: The LM5100M boasts fast propagation delays, which minimizes transition times and reduces switching losses.
• Protection Features: It includes over-temperature protection and dead-time insertion to prevent shoot-through, enhancing system reliability.

Applications:

• Switch Mode Power Supplies (SMPS)
• DC to DC Converters
• Motor Controllers
• Inverters
• Class-D Audio Amplifiers

The LM5100M is available in a variety of packages, including the space-saving 8-pin SOIC and 8-pin VSSOP, providing flexibility to meet the needs of compact designs. With its combination of high-voltage capability, high drive current, and integrated features, the LM5100M from Texas Instruments stands out as a superior solution for your high-efficiency power management designs.
