5. Electrical Characteristics

Under development Preliminary document

Specifications in this document are tentative and subject to change.

Notes:

1. Vcc = 1.8 V to 5.5 V at Topr =

−20°C to 85°C (N version)/−40°C to 85°C (D version), unless otherwise specified.

2. The average output current indicates the average value of current measured during 100 ms.

3. fOCO40M can be used as the count source for timer RC in the range of Vcc = 2.7 V to 5.5 V.
