HY2131
Protection IC for 2/3-Cell Lithium Ion/Lithium Polymer Batteries in Series
1. General Description
The series of HY2131 ICs is a secondary protection IC for lithium ion/lithium polymer rechargeable
batteries and it also comprises high-accuracy voltage detectors and delay circuits.
These ICs are applicable to protect overcharge of 2/3-cell lithium ion/lithium polymer rechargeable
batteries.
2. Features
The features that whole series of HY2131 comprised are as follows:
(1) High-accuracy voltage detection circuit
Overcharge detection voltage VCUn (n = 1, 2, 3) 4.000V to 4.550V
Accuracy: ±20mV
Accuracy: ±50mV
Accuracy: ±0.4V
Overcharge release voltage VCRn (n = 1, 2, 3)
Standby detection voltage VSBn (n = 1, 2, 3)
3.800V to 4.500V
3.500V
(2) Delay time is set by internal circuit (external capacitor is not needed)
6.0s
Accuracy: ±20%
(3) Delay time shortening function: overcharge detection delay time can be shortened by specific setup.
12ms Accuracy: ±50%
For EX, as VC2 = VC3 = VSS, the overcharge detection delay time of cell1 is shortened;
as VC1 = VC2, VC3 = VSS, the overcharge detection delay time of cell2 is shortened;
as VC1 = VC2 = VC3, the overcharge detection delay time of cell3 is shortened.
.
(4) Output logic: Active high CMOS output; the high level is 4.7V (typical) output from regulator.
(5) Low current
Operation mode
Standby mode
3.0μA typ., 6.0μA max. (VCelln =3.9V)
0.5μA max. (VCelln = 3.1V)
(6) Selection of 2-cell/3-cell application: either 2-cell or 3-cell is selectable by means of external circuit.
(7) High voltage resistant design: the absolute maximum rated value is 30V.
(8) Wide operating temperature range: -40 ℃ ~ +85 ℃
(9) Small package: TSOT-23-6
(10) Halogen free green product

In terms of the order of connecting cells, the positive terminal of the cell 1 should be the last. Otherwise,
COUT may output “H” tentatively, and the fuse may be fused, but IC is not damaged. Connect
sequesnces must be used as following:

Cell3 -> Cell2 -> Cell1
Cell2 -> Cell3 -> Cell1
2-series cell configuration

*1. RVDD and CVDD are capable of VDD voltage stabilization. If RVDD is connected with an over small
resistor, IC operation may be unstable because there is larger fluctuation on Cell voltage due to
current. If RVDD is connected with an over large resistor, unpredicted result may be resulted from
.
voltage difference between voltages on VDD pin and VC1 pin because of voltage difference across
RVDD due to current consumption of the IC itself. Therefore, RVDD is ranged from 100Ω ~ 1KΩ and
CVDD is ranged from 0.01μF ~ 1.0μF, and never connect capacitor below 0.01μF.
*2. R1 ~ R3 and C1 ~ C3 are capable of stabilizing voltages of cell1 ~ cell3. If R1 ~ R3 are connected to
over large resistor, detection voltage precision would be impacted because of voltage difference due
to current consumption. Therefore, R1 ~ R3 should be connected with resistor below 1KΩ, and C1 ~
C3 should be connected with capacitor equal to or above 0.01μF.
3. The typical application circuit diagram above is only for reference. The performance of the circuit
depends on PCB layout and external components to a great extent. Sufficient evaluation and test are
necessary in real application.
4. Both overvoltage and over-current shall not exceed the absolute maximum values of the IC and its
peripheral devices. As overcharge protection status is detected, large current would flow through FET
until the fuse is broken. In order to guarantee undamaged FET, the current resistance value for the
FET should be sufficiently large.
5. If SC protection is to be connected, it has to be connected to the battery as the last one. In connecting
cell, the positive pole of Cell1 has to be connected as the last one. Otherwise, COUT pin might output
high level to result in fused Fuse. The SC protector is Zip code 141-0032 (Sony Chemical &
Information Device Company Ltd.).
Caution:
1. The parameters above may be changed without announce in advance. Please download the latest

HY2131
Protection IC for 2/3-Cell Lithium Ion/Lithium Polymer Batteries in Series
12.Description of Operation
12.1.Overcharge Status
This IC detects voltage of battery 1 connected between VC1 and VC2 pins, voltage of battery 2
connected between VC2 and VC3 pins and voltage of battery 3 connected between VC3 and VSS
continuously to control charging. When voltage of one battery is higher than or equal to the overcharge
detection voltage (VCUn) and the sustaining time of such status is larger than or equal to the
overcharge detection delay time (TOCn), the output voltage on COUT pin of the IC becomes high level
from low level, such that the MOSFET for charging control is switched off, and charging is stopped.
Such status is referred to as “overcharge status”.
Overcharge status release: When the voltages of battery 1, battery 2 and battery 3 are all lower than
or equal to the overcharge release voltage (VCRn) and the sustaining time of such status is larger than
or equal to the overcharge release delay time (TCRn), the output voltage on COUT pin of the IC
becomes low level from high level, such that the overcharge status is released and normal operating
status is returned.
Caution:
(1) The overcharge delay time is a built-in fixed output. If the overcharge detection counter is reset, the
overcharge protection status would be released and the normal status would be returned.
(2) The IC would still enter the overcharge protection status even though only the voltage of one
battery keeps higher than the overcharge detection voltage and the sustaining time is beyond the
.
overcharge detection delay time.
(3) If the voltage of one battery is higher than the overcharge detection voltage due to noise or other
causes while the voltages of batteries 1, 2 and 3 are all lower than the overcharge detection voltage in
the overcharge detection delay time, the sustained period of time with voltage higher than the
overcharge detection voltage would be retained and accumulated. As the accumulated time is larger
than the overcharge detection delay time, the IC would enter “overcharge status”.
(4) After overcharge protection, the overcharge protection status would not be released if the voltage
of at least one battery is higher than the overcharge release voltage in the overcharge release delay
time even though the voltages of all batteries are equal to or lower than the overcharge release
voltage.
(5) The output type of COUT pin is active high CMOS. The output voltage is between VSS and the
output voltage of internal regulator. The high level is provided by the internal regulator with 4.7 V as
typical value.

page22
HY2131
Protection IC for 2/3-Cell Lithium Ion/Lithium Polymer Batteries in Series
12.2.Standby Status
As the voltages of batteries 1, 2 and 3 are all lowered to the standby detection voltage (VSB), the
current consumption of the IC is reduced to the current consumption value in standby, which status is
referred to as “standby status”, for battery in normal operating status in a discharging process. At the
moment, the maximum value of current consumption is 0.5 uA. After the IC enters the standby status,
the standby status would be released and the normal operating status would be returned whenever
the voltage of a certain battery is higher than or equal to the standby detection voltage (VSB).
12.3. Test Time Shortening Capability
In addition to the voltage under detection, the test time for overcharge protection delay time and the
overcharge release delay time of the battery under detection may be reduced by shorting the positive
and negative poles of the other two batteries.
