Preliminary
BATTERY PROTECTION IC
WITH CELL-BALANCE
FUNCTION
CMOS IC
DESCRIPTION
The UTC UB209A Series is a protection IC for
lithium-ion/lithium polymer rechargeable batteries, including a high
precision voltage detection circuit and a delay circuit.
The UTC UB209A Series has a transmission function and two
types of cell-balance function so that users are also able to
configure a protection circuit with series multi-cell.
FEATURES
* Settable delay time by external capacitor for output pin
* High-accuracy voltage detection circuit
* Two types of cell-balance function: charge/discharge
* Control charging, discharging, cell-balance by CTLC, CTLD pins
* Low current consumption: 8.0µA max
* Wide range of operation temperature (-40°C~+85°C)

Notes:1.In the UTC UB209A Series, users are able to set delay time for the output pins. By using the following
formula, delay time is calculated with the value of CDT pin’s resistance in the IC (RCDT) and the value of
capacitor set externally at the CDT pin (CCDT).
tD [s]=-ln(1-VCDET /VDS)×CCDT [µF]×RCDT [MΩ]
=-ln (1-0.7(Typ.) )×CCDT [µF]×8.31MΩ (Typ.)
=10.0MΩ(Typ.)×CCDT [µF]
In case of the capacitance of CDT pin CCDT=0.01µF, the output pin delay time tD is calculated by using the
above formula and as follows.
tD [s]=10.0MΩ(Typ.)×0.01µF=0.1s(Typ.)
Test RCDT and the CDT pin detection voltage (VCDET) by test circuits shown in this datasheet after applying
the power supply while pulling-down the CTLC, CTLD pins to the level of VSS pin outside the IC.
2.In case of using CTLC, CTLD pins pulled-down to the level of VSS pin externally, the current flows into the
VDD pin (IDD) is calculated by the following formula.
IDD=IOPE+ICTLCH+ICTLDH
