Gate Drivers ICs

TD350IDT Description

The TD350IDT from STMicroelectronics is a high-side gate driver IC designed for demanding power electronics applications. Packaged in a 14-pin SO surface-mount configuration, it operates within a 12V to 26V supply range, making it suitable for high-voltage systems. This single-channel driver delivers peak output currents of 1.5A (source) and 2.3A (sink), ensuring robust switching performance for MOSFETs and IGBTs. With fast rise/fall times (130ns typical, 75ns max), it minimizes switching losses, improving efficiency in high-frequency circuits. The device is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.
