Charge balance control
*1. If R1-5 connects with an over-spec resistor, battery accuracy may be influenced due to current
consumption cause R1 voltage drops. When a charger is connected in reversed, the current flows
from the charger to the IC. At this time, if R1 is too high, the voltage between VDD pin and VSS pin
may exceed the absolute maximum rating.
*2. RB1-5 connects with an under-spec resistor, when battery voltage exceed Overcharge Detection
Voltage (VCU) will let charge current suddenly become large, which may result in charge overcurrent
phenomenon which allows circuit system be protected and can not be charged.
*3. C1-5 can stabilize the supply voltage of VDD, Do not connect capacitor that under 0.01μF.
*4. To select N-MOSFET or P-MOSFET, depends on the product type.
Caution：
1. The above constants may be changed without notice, please download the most up-to-date datasheet

1 Cell Li-ion/Polymer Battery Charge Balance IC
10. Description of Operation
10.1.
Normal Status
This IC continuously monitors the voltage of the battery connected between the VDD and
VSS, to control charge and discharge. When battery voltage exceed overcharge detection
voltage (VCU), OUT pin output electrical level will change from high to low to control
P-MOSFET or OUT pin electrical level change from low to high to control N-MOSFET; or
the voltage of the battery cell lower than the overcharge release voltage (VCR), OUT pin
output electrical level change from low to high to control P-MOSFET or OUT pin output
electrical level change from high to low to control N-MOSFET to turn off. This status is
called “Normal status" Which also can freely operate while charging.
10.2.
Overcharge Status
Under the normal status, as soon as the battery voltage becomes higher than the
overcharge detection voltage (VCU) during charge and the detection time continues longer
than the overcharge detection delay time (TOC); or the voltage of the battery voltage lower
than the overcharge release voltage(VCR), HY2212 Series IC will turn the MOSFET (OUT
pin) on or off, this condition is called the “Overcharge status”or “Charge balance
control”.
Overcharge status has following two options turning charge control balance MOSFET on
and off :
.
(1) Selection of HY2212-xxxA series, using the N-MOSFET as the charge balance control
(a) During charging process, the battery voltage becomes higher than the overcharge
detection voltage (VCU) and the detection time continues longer than the overcharge
detection delay time (TOC), OUT pin will produce LH to turn on N-MOSFET.
(b) During charging process, the battery voltage is lower than the overcharge release
voltage (VCR), OUT pin produces HL to turn off the N-MOSFET.
(2) Selection of HY2212-xxxB series, using P-MOSFET as the charge balance control.
(a) During charging process, the battery voltage becomes higher than the overcharge
detection voltage (VCU) and the detection time continues longer than the overcharge
detection delay time (TOC), OUT pin will produce H L to turn on P-MOSFET.
(b) During charging process, the battery voltage is lower than the overcharge release
voltage measurement (VCR), OUT pin produces LH to turn off the P-MOSFET.
10.3.
Standby Status
Under normal status，During discharge process, when battery voltage drops lower than
Standby Detection voltage(VSB), IC current consumption minimize to standby status current
consumption value, this status is called “Standby Status”.
