Product Overview: LM5111-2MY/NOPB

The LM5111-2MY/NOPB is a dual 5A compound gate driver designed by Texas Instruments. It is specifically engineered to drive both the high-side and low-side N-Channel MOSFETs in a synchronous buck or half-bridge configuration. This versatile driver is well-suited for a wide array of applications, including switch-mode power supplies, motor control circuits, and other power conversion and management tasks requiring efficient and reliable switching.

Key Features

• High Current Drive Capability: The LM5111-2MY/NOPB can deliver peak output currents of up to 5A, providing the necessary drive strength for most power MOSFETs.
• Independent Inputs: Separate inputs for the high-side and low-side drivers allow for flexible control strategies and simplified interfacing with PWM controllers.
• Adaptive Dead-Time Control: This feature helps prevent cross-conduction and ensures efficient operation by automatically adjusting the dead-time between the high-side and low-side drivers.
• Under-Voltage Lockout (UVLO): The built-in UVLO feature protects the device and the power MOSFETs from operating at insufficient gate-source voltages.
• Wide Supply Voltage Range: The LM5111-2MY/NOPB operates over a broad supply voltage range, accommodating various system voltages and ensuring versatility across different applications.
