TND322VD-TL-E

Full Half-Bridge (H Bridge) Drivers Overview

The TND322VD-TL-E is a half-bridge driver manufactured by onsemi, designed for driving external power MOSFETs or IGBTs. It operates within a supply voltage range of 4.5V to 25V and delivers a peak output current of 800mA. The device features a typical on-resistance of 11 ohms and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in an 8-SMD, flat lead (SOT-28FL/VEC8) surface-mount format, it supports high-frequency switching applications requiring robust gate drive capabilities.
