Notes

13.

With CAN cell in Sleep-Disable state. If CAN cell is Sleep-Enabled for wake-up, an additional 60 µA must be added to specified value.

14.

IDD1 is the total regulator output current. VDD specification with external capacitor. Stability requirement: C > 47 µF ESR < 1.3 Ω

(tantalum capacitor). In reset, normal request, normal and standby modes. Measure with C = 47 µF Tantalum.

15.

Guaranteed by design; however, it is not production tested.

Table 3. Static Electrical Characteristics (continued)

Characteristics noted under conditions 5.5 V

≤ V

SUP ≤ 18 V, - 40°C ≤ T

A ≤ 125°C, GND = 0 V unless otherwise noted. Typical

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