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 catastophic 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 present between charger input and battery.
4
Delay set by external capacitor on the RESCAP pin.
Specifications subject to change without notice.
