LION BATTERY PROTECTION
IC FOR 1-SERIAL TO
4-SERIAL-CELL PACK
(SECONDARY PROTECTION)
DESCRIPTION
The UTC UB240 Series is secondary protection IC for 1-, 2-,
3-, or 4-Cell lithium-ion rechargeable battery packs, and
incorporates a high-accuracy voltage detection circuit.
The UTC UB240 Series also includes a high accuracy delay
circuit for over voltage detection time can be set by an external
capacitor.
FEATURES
* High-accuracy voltage detection circuit for each cell
* Overcharge detection voltage n (n=1 to 4): 4.05V to 4.50V
(in 50mV steps)
* Overcharge hysteresis voltage n (n=1 to 4): 0.25V±0.07V,
0.30V±0.10V
* Delay times for overcharge detection can be set by an external
capacitor
* CMOS output active “H”
* Wide operating voltage range 3.6V to 24V
* Wide operating temperature range 40°C to +85°C
* Low current consumption: 1.5μA typ. (+25°C) at 3.5V for each
cell
