The LM5101BMA from Texas Instruments is a high-voltage gate driver designed to drive both the high-side and low-side N-Channel MOSFETs in a synchronous buck or a half-bridge configuration. Its robust design is ideal for a wide range of applications, including motor control, power supplies, and automotive systems.

Key Features

• High Voltage Range: The device can handle voltages up to 100V, making it suitable for high-voltage power management applications.
• High Peak Output Drive: With peak output currents of +/-1.5A, the LM5101BMA can effectively switch power MOSFETs at high speeds, reducing switching losses and improving efficiency.
• Adaptive Dead-Time Control: This feature minimizes cross-conduction and shoot-through in MOSFETs, which is critical for maintaining system efficiency and reliability.
• Under-Voltage Lockout (UVLO): The integrated UVLO feature ensures that the driver operates at safe voltage levels, preventing damage to the MOSFETs due to insufficient gate voltage.
• Robustness: The device includes protection features such as thermal shutdown and fault reporting to ensure reliable operation under adverse conditions.
