NOTES
1All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.
2This 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.
3No isolation diode is present between the charger input and the battery.
4Delay set by external capacitor on the RESCAP pin.
Specifications subject to change without notice.
