STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics
Characteristics noted under conditions of 3.0 V ≤ VDD ≤ 5.5 V, 6.0 V ≤ VPWR ≤ 32 V, -40°C ≤ TC ≤ 125°C, and calibrated
timers, unless otherwise noted. Where typical values reflect the parameter’s approx. average value with VPWR = 13 V, TA =
25°C.

Notes
10. This parameter is guaranteed by design, however is not production tested.
11. Assuming Ideal external 10:1 Voltage Divider. Tolerance of 10:1 Voltage Divider is not included. Voltage is measured on the High End of
Divider - not at the pin. 10:1 N.3.A 10:1 Voltage Divider is produced using two resistors with a 9:1 resistance ratio by the basic formula:
V-----O-----U-----T-- _{= --------}R_-----1_---------
VIN R1 + R2
Where R2 = 9XR1
