Notes

13.

Guaranteed by Design

14.

When battery voltage is higher than 5.0V, a diode implementation like the one displayed on VG is necessary.

Table 4. Static Electrical Characteristics (continued)

Characteristics noted under conditions 2.7V

≤ VIN ≤ 5.5V, -20°C ≤ TA ≤ 85°C, GND = 0V, unless otherwise noted. Typical

values noted reflect the approximate parameter means at TA = 25°C under nominal conditions, unless otherwise noted.
