Notes

12.

OLLED1, bit D0 in SI data is set to [0].

13.

OLLED1, bit D0 in SI data is set to [1].

14.

For typical value of ICS FSR, ICSNS = 5.0 mA. If the range is exceeded, no current clamp and the precision is no more guaranteed.

15.

Parameter guaranteed by design; however, it is not production tested.

16.

Source-to-Drain ON Resistance (Reverse Drain-to-Source ON Resistance) with negative polarity VBAT..

17.

OLLED2, bit D1 in SI data is set to [0].

18.

OLLED2, bit D1 in SI data is set to [1].

19.

For typical value of ICS FSR, ICSNS = 5.0 mA. If the range is exceeded, no current clamp and the precision is no more guaranteed

Table 3. Static Electrical Characteristics (continued)

Characteristics noted under conditions 4.5 V

≤ VCC ≤ 5.5 V, 7.0 V ≤ VBAT ≤ 18 V, -40°C ≤ TA ≤ 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.
