Présentation
Description
SI7866ADP-T1-E3 is a high‑voltage isolated gate‑driver IC used to drive power MOSFETs/IGBTs in motor drives, inverters, and switch‑mode power supplies. It provides galvanic isolation between the logic and power domains, accepts PWM or logic‑level inputs, and outputs isolated gate signals. Typical protections include undervoltage lockout, overcurrent/short‑circuit protection, and fault reporting. The device is designed for automotive/industrial environments and is offered in a T1 package; exact voltage ratings, isolation voltage (IsolV), and pinout vary by variant. For precise intro, refer to the manufacturer’s datasheet for the specific numbers and application notes. If you share the manufacturer or a link, I can give a tighter summary with exact specs.
Pinout
- Pin count: 16 pins (SOIC-16 package)
- Function: Isolated dual gate driver for IGBT/MOSFET applications; provides independent high-side and low-side gate drive signals from a logic input with an isolated power supply and protection features (e.g., UVLO).
