UB264B
Preliminary
LION BATTERY PROTECTION
IC FOR 2-SERIAL, 3-SERIAL,
OR 4-SERIAL-CELL PACK
(SECONDARY PROTECTION)
„ DESCRIPTION
The UTC UB264B Series is secondary protection IC for 2-, 3-, or
4-Cell lithium-ion rechargeable battery packs, and incorporates a
high-accuracy voltage detection circuit.
The UTC UB264B Series also includes a high accuracy delay
circuit for over voltage detection time without external capacitors.
„ FEATURES
* High-accuracy voltage detection circuit for each cell
* Overcharge detection voltage n (n=1 to 4): 4.30V to 4.80V (in
50mV steps)
* Overcharge hysteresis voltage n (n=1 to 4): -0.52V±0.21V,
0.39V±0.16V, 0.26V±0.11V, 0.13V±0.06V, None
* Delay times for overcharge detection can be set by an internal
circuit without external capacitors
* Output latch function after overcharge detection
* CMOS output active “H”
* Wide operating voltage range 3.6V to 24V
* Wide operating temperature range 40°C to +85°C
* Low current consumption: 2.5μA typ. (+25°C) at 3.5V for
each cell

„ OPERATING(Cont.)
Notes: 1. The reverse voltage “H” to “L” or “L” to “H” of CTL pin is VDD pin voltage 2.8 V (Typ.), does not have
the hysteresis.
2. Since the CTL pin implements high resistance of 8Mto 12Mfor pull down, be careful of external
noise application. If an external noise is applied, CO may become “H”. Perform thorough evaluation
using the actual application.
3. In the UTC UB264B Series, when the CTL pin is open or “L”, CO latches “H”. When the VDD pin
voltage is decreased to the UVLO voltage of 2 V (Typ.) or lower, the latch is reset.
4. Test Mode
In the UTC UB264B Series, the overcharge detection delay time (tCU) can be shortened by entering the test mode.
The test mode can be set by retaining the VDD pin voltage 8.5 V or more higher than the SENSE pin voltage for at
least 80ms (V1=V2=V3=V4=3.5 V, Ta=25°C). The status is retained by the internal latch and the test mode is
retained even if the VDD pin voltage is decreased to the same voltage as that of the SENSE pin. When CO becomes
“H” when the delay time has elapsed after overcharge detection, the latch for retaining the test mode is reset and the
UTC UB264B Series exits from the test mode.

Notes: 1. When the VDD pin voltage is decreased to lower than the UVLO voltage of 2 V (Typ.), the UTC
UB264B Series returns to the normal mode.
2. Set the test mode when no batteries are overcharged.
3. The overcharge release delay time (tCL) is not shortened in the test mode.
4. The overcharge timer reset delay time (tTR) is not shortened in the test mode.
