EUP9232
LI-ION/POLYMER TWO CELL PROTECTOR
DESCRIPTION
The EUP9232 Series are lithium-ion rechargeable battery protection ICs incorporating high-accuracy voltage
detection circuits and delay circuits. The EUP9232 Series are suitable for a 2-cell serial lithium- ion battery
pack.
FEATURES
Highly accurate voltage detector…………...Overcharge detection (Topt=+25°C)
Overcharge hysteresis
Overdischarge detection
Overcurrent 1 detection
Variety of detector……………………………Overcharge detection
Overcharge hysteresis
Overdischarge detection
Overdischarge hysteresis
Overcurrent 1 detection
Overcurrent 2 detection
*1 Overcharge release voltage=Over detection voltage-Overcharge hysteresis voltage
*2 Overdischarge release voltage = Overdischarge detection voltage-Overdischarge hysteresis voltage.

High input-voltage device: Absolute maximum ratings 28V
Wide operating voltage range :2 to 16V
The delay time for every detection can be set via an external capacitor.
(Each delay time for Overcharge detection, Overdischarge detection, Overcurent detection are
“Proportion of hundred to ten to one”.)
Two overcurrent detection levels (Protection for shourt-circuiting)
Internal auxiliary over voltage detection circuit (Fall-safe for overcharge detection voltage)
Internal charge circuit for 0V battery (Unavailable is option)
Low current consumption
Operation mode:
5µA typ. 12µA max. (-40 to +85°C)
Power-down mode 0.1µA max. (-40 to +85°C)
Package: TSSOP-8
RoHS compliant and 100% lead (Pb)-free
APPLICATIONS
Lithium-ion rechargeable battery packs.
