UB209B Datasheet

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.
* 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)
