UB209B

DESCRIPTION

The UTC UB209B 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 UB209B 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)
