Overview
The LM5106MM, produced by Texas Instruments, is a high-voltage gate driver designed to drive both the high-side and low-side N-Channel MOSFETs in synchronous buck or half-bridge configurations. This device is capable of handling rail voltages up to 100V, making it suitable for high-power applications. The LM5106MM features a single TTL-compatible input and allows for programmable turn-on delays (dead-time) using a single external resistor. It operates with robust level shift technology, ensuring high-speed operation while maintaining low power consumption and clean output transitions. The device includes under-voltage lockout (UVLO) to disable the gate driver when the supply voltage is below the operating threshold and is available in both VSSOP-10 and thermally enhanced 10-pin WSON plastic packages.
