BATTERY PROTECTION IC

WITH CELL-BALANCE

FUNCTION



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)
