NOTES:

7. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization

and are not production tested.

8. For more detailed information regarding I2C timing characteristics refer to Table 2 on page 17.

9. Parameters established by bench testing and/or design. Not production tested.

Electrical Specifications VIN = 3.7V, unless otherwise noted. Typical specifications are characterized at TA = +25°C unless

otherwise noted. Boldface limits apply across the operating temperature range, -40°C to +85°C. (Continued)
