Product Overview: LM5100CMA/NOPB High Voltage Gate Driver

The LM5100CMA/NOPB is a high-performance gate driver designed and manufactured by Texas Instruments. It is specifically engineered to drive both the high-side and low-side N-Channel MOSFETs in a synchronous buck or a half-bridge configuration. This component is a critical piece for power management applications, ensuring efficient and reliable operation of power conversion systems.

Key Features

• High Voltage Range: The LM5100CMA/NOPB is capable of operating with supply voltages up to 100V, making it suitable for a wide range of power applications.
• High Drive Capability: It boasts a strong drive capability with peak output currents of 1.5A for the high-side and 2.5A for the low-side, providing robust drive strength for MOSFETs.
• Independent Inputs: Separate inputs for high-side and low-side gates offer design flexibility and the ability to implement advanced control schemes.
• Bootstrap Feature: The integrated bootstrap diode simplifies the design by reducing external component count.
• Protection Features: It includes under-voltage lockout (UVLO) for both channels, ensuring that the gates are only driven when there is sufficient voltage to do so properly.
• Fast Propagation Delays: The device has fast propagation delays and matched rise and fall times to minimize the transition periods and reduce switching losses.
• Thermal Shutdown: An integrated thermal shutdown feature protects the device from overheating, enhancing system reliability.
