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 125 C. Operation beyond 125 C could cause
permanent damage to the device.
3 Delay set by external capacitor on the RESCAP pin.
Specifications subject to change without notice.
