UB240 LION BATTERY PROTECTION IC

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 ca.

UB240 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
