Product Overview: Texas Instruments LM5104M/NOPB

The LM5104M/NOPB is a high-voltage gate driver designed by Texas Instruments to provide robust and efficient control for MOSFETs and IGBTs. This gate driver is particularly suitable for switch-mode power supplies, motor control applications, and other power conversion systems that require high-speed and high-power gate control.

Key Features

• High-Voltage Capability: The LM5104M/NOPB is capable of handling voltages up to 100V, making it suitable for a wide range of high-voltage applications.
• Dual Outputs: It features dual outputs for driving the gates of both high-side and low-side power MOSFETs, providing flexibility in various circuit topologies.
• Fast Propagation Delays: With propagation delays typically under 35ns, the device ensures quick response times, which is critical for high-frequency switching applications.
• Robust Output Drive: The gate driver can source up to 1A and sink up to 2A, providing strong drive capability for rapid charging and discharging of gate capacitances.
• Under-Voltage Lockout (UVLO): The built-in UVLO feature protects the power switches by ensuring that the gate driver only operates when the supply voltage is sufficient.
• Matched Propagation Delays: The LM5104M/NOPB offers matched propagation delays between the high-side and low-side drivers, which is essential for minimizing dead-time and preventing shoot-through.
• Thermal Shutdown: An integrated thermal shutdown feature enhances system reliability by turning off the driver if the die temperature exceeds safe operating limits.

Applications

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