NOTES
1
All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.
2
This feature is intended to protect against catastrophic failure of the device. Maximum allowed operating junction temperature is 125oC. Operation beyond 125oC
could cause permanent damage to the device.
3
No isolation diode is present between the charger input and the battery.
4
Delay set by external capacitor on the RESCAP pin.
Specifications subject to change without notice.
