The LM5100BMAX is a high-voltage gate driver designed and manufactured by Texas Instruments, renowned for its precision and reliability in electronic components. This advanced driver is specifically engineered to drive both the high-side and low-side N-channel MOSFETs and IGBTs in a synchronous buck or a half-bridge configuration. It is an ideal choice for a wide range of applications, including motor drives, power supplies, and high-power inverters.
Key Features
- High Voltage Range: The LM5100BMAX operates with a voltage range of up to 100V, making it suitable for high-voltage applications.
- High Drive Current: It provides robust drive currents of 1.5A for the high-side and 2.5A for the low-side, ensuring efficient switching of connected MOSFETs or IGBTs.
- Independent Inputs: Separate inputs for high and low drivers allow for flexible control strategies, including non-synchronous switching.
- Under-Voltage Lockout (UVLO): The built-in UVLO feature for both the high-side and low-side drivers ensures that the device operates safely by preventing the driver from turning on if the supply voltage is too low.
- Fast Propagation Delays: The device boasts fast propagation delays and matched rise and fall times, which contribute to the efficiency of the power conversion process.
- Cross-Conduction Prevention: Integrated circuitry minimizes the risk of cross-conduction and shoot-through in the power stage.
