UB264A Datasheet

LION BATTERY PROTECTION IC FOR 2-SERIAL, 3-SERIAL, OR 4-SERIAL-CELL PACK (SECONDARY PROTECTION)
 

 
DESCRIPTION
 
The UTC UB264A 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 UB264A 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 control function via CTL pin
* CMOS output active “H”
* Wide operating voltage range 3.6V to 24V
* Wide operating temperature range −40°C ~ +85°C
* Low current consumption: 2.5μA typ. (+25°C) at 3.5V for each cell
