ELECTRICAL CHARACTERISTICS (continued)
Note 3: Electrical Characteristics state DC and AC electrical specifications under particular test conditions which
guarantee specific performance limits. This assumes that the device is within the recommended operating Range.
Specifications are not guaranteed for parameters where no limit is given, however, the typical value is a good
indication of device performance.
Note 4: Typicals are measured at 25˚C and represent the parametric norm.
Note 5: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 6: Supply current includes PROG pin current (approximately 100uA) but does not include any current
delivered to the battery through the BAT pin (approximately 100mA).
