1. Normal Status
In the UTC UB209A, both of CO and DO pin get the VSS level; the voltage between VDD and VSS (VDS) is more
than the overdischarge detection voltage (VDL), and is less than the overcharge detection voltage (VCU) and
respectively, the CTLC pin input voltage (VCTLC)<the CTLC pin voltage “H” (VCTLCH), the CTLD pin input voltage
(VCTLD)<the CTLD pin voltage “H” (VCTLDH). This is the normal status.
2. Overcharge Status
In the UTC UB209A, the CO pin is in high impedance; when VDS gets VCU or more, or VCTLC gets VCTLCH or more.
This is the overcharge status.
If VDS gets the overcharge release voltage (VCL) or less, and VCTLC gets the CTLC pin voltage “L” (VCTLCL) or less,
the UTC UB209A releases the overcharge status to return to the normal status.
3. Overdischarge Status
In the UTC UB209A, the DO pin is in high impedance; when VDS gets VDL or less, or VCTLD gets VCTLDH or more.
This is the overdischarge status.
If VDS gets the overdischarge release voltage (VDU) or more, and VCTLD gets the CTLD pin voltage “L” (VCTLDL) or
less, the UTC UB209A releases the overdischarge status to return to the normal status.
4. Cell-balance Function
In the UTC UB209A, the CB pin gets the level of VDD pin; when VDS gets the cell-balance detection voltage (VBU)
or more. This is the charge cell-balance function.
If VDS gets the cell-balance release voltage (VBL) or less again, the UTC UB209A sets the CB pin the level of VSS
pin.
In addition, the CB pin gets the level of VDD pin; when VDS is more than VDL, and VCTLD is VCTLDH or more. This is
the discharge cell-balance function.
If VCTLD gets VCTLDL or less, or VDS is VDL or less again, the UTC UB209A sets the CB pin the level of VSS.
5. Delay Circuit
In the UTC UB209A, users are able to set delay time which is from detection of changes in VDS, VCTLC, VCTLD to
output to the CO, DO, CB pin.
For example in the detection of overcharge status, when VDS exceeds VCU, or VCTLC gets VCTLCH or more, charging
to CCDT starts via RCDT. If the voltage between CDT and VSS (VCDT) reaches the CDT pin detection voltage (VCDET),
the CO pin is in high impedance. The output pin delay time tD is calculated by the following formula.
tD [s]=10.0MΩ (Typ.)×CCDT [µF]
The electric charge in CCDT starts to be discharged when the delay time has finished.
The delay time that users have set for the CO pin, as seen above, is settable for each output pin DO, CB.
