Notes:
1. V
CC = 1.8 to 5.5 V and Topr = −20 to 85 °C (N version)/−40 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, timer RD or timer RG in the range of V
CC = 2.7 to 5.5 V.
