SELECTION GUIDE
In the RV5VG1×××series, the overcharge/excessive discharge detector threshold, respective hysteresis ranges,
short-circuit detector threshold and taping type can be selected at the user's request.
The selection can be made by designating the part number as shown belows.

ranges, and short-circuit detector threshold.
Designation of release conditions of voltage detector.
C : VD1 (After over-charge detection)...................when battery voltage falls below VDET1–VHYS1 or a
load resistance is applied.
b
VD2 (After excessive-discharge detection)......when a charger is connected.
D : VD1 (After over-charge detection)...................when battery voltage falls below VDET1–VHYS1.
VD2 (After excessive-discharge detection) ^.....when battery voltage rises above VDET2+VHYS2 or a
charger is connected.
Designation of Taping Type:
c
EX. 8pin SSOP: E1, E2
(refer Taping Specifications)
“E2” is prescribed as a standard.
