The LM5100BSD/NOPB is a high-voltage gate driver designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This device is specifically engineered to drive both the high-side and low-side N-Channel MOSFETs in a synchronous buck or a half-bridge configuration. It is an essential component for power management applications across a wide range of industries, including automotive, industrial, and consumer electronics.

Key Features

• High-Voltage Capability: The LM5100BSD/NOPB is capable of handling voltages up to 100V, making it suitable for high-voltage power conversion systems.
• Advanced Drive Circuitry: It features a robust drive circuitry that ensures fast and reliable switching of MOSFETs, which is critical for efficiency and performance in power converters.
• Bootstrap Operation: The device supports bootstrap operation, which allows for the high-side N-Channel MOSFET to be driven above the supply voltage, providing greater flexibility in circuit design.
• Independent Inputs: Separate inputs for high-side and low-side gates provide designers with control flexibility and the ability to implement various PWM schemes.
• Under-Voltage Lockout: An integrated under-voltage lockout feature ensures that the gate driver operates only when the supply voltage is within an acceptable range, thus protecting the system from potential damage.
• Thermal Shutdown: The LM5100BSD/NOPB includes a thermal shutdown mechanism to prevent overheating, further enhancing the reliability and longevity of the device.
