Fault protection covers over-current, over-temperature, and over-voltage conditions, reducing external supervisory circuitry. ## Charge current and thermal budget Supply voltage ceiling is 6.2 V, so a 5 V USB bus or a regulated adapter rail is the typical input; the I²C bus lets the host adjust the charge current in real time. ROHS3 compliant.
