BD6046GUL is a charge protection IC with built-in FET negative voltage protection produced by ROHM. It can prevent negative voltage caused by USB reverse insertion without any additional components, and also has overvoltage protection, overcurrent protection, temperature protection and other functions.
The BD6046GUL is a charge‑protection IC that safeguards devices from abnormal input voltage at a USB port, including protection against reverse insertion. It offers over‑voltage protection up to 28 V, negative‑voltage protection, an internal low‑Ron FET, OVLO, UVLO, over‑current and thermal shutdown functions, all in a compact VCSP50L2 package.
