LOW VOLTAGE DETECTOR S3F80P5_UM_ REV1.00
NOTES
1. A term of LVD is a symbol of parameter that means ‘Low Level Detect Voltage for Back-Up Mode’.
2. A term of LVD_FLAG is a symbol of parameter that means ‘Low Level Detect Voltage for Flag
Indicator’.
3. The voltage gaps (LVD_GAPn (n=1~4)) between LVD and LVD FLAGn(n=1~4) have ± 80mV distribution.
LVD and LVD FLAGn(n=1~4) are not overlapped
