Product Overview: LM5104SDX/NOPB

The LM5104SDX/NOPB is a high-voltage gate driver designed and manufactured by Texas Instruments. This component 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 a pivotal element in power management applications, particularly in those requiring efficient and reliable switching operations.

Key Features

• High Voltage Capability: The LM5104SDX/NOPB can handle voltages up to 100V, making it suitable for various high-voltage applications.
• High Peak Output Current: With a peak output current of 1A for the high-side and 2A for the low-side, this gate driver can effectively drive large MOSFETs with high gate capacitances.
• Independent Inputs: Separate inputs for the high-side and low-side drivers provide flexible control and enable the use of different PWM or control signals for each side.
• Adaptive Anti-Cross-Conduction Protection: To prevent simultaneous conduction of both the high-side and low-side MOSFETs, the device includes an adaptive anti-cross-conduction circuit.
• Under-Voltage Lockout (UVLO): The built-in UVLO feature ensures that the driver operates only when the supply voltage is sufficient, thus protecting the MOSFETs and the system.
