ML5243-001

5-Series Cell Li-ion Rechargeable Battery Protection IC

■ General Description

The ML5243 is a protection IC for the 5-cell Li-ion rechargeable battery pack. It detects individual cell

overvoltage/undervoltage and the pack overcurrent/over-temperature, and its output signal indicates

charge/discharge enable. And it has open-wire detection function of battery connection wire.

■ Features

• 3 to 5 cell high-precision overvoltage and undervoltage detection function

Voltage detecting function for individual cells

Overvoltage detection threshold

2^ndovervoltage detection threshold

Undervoltage detection threshold

4.225 V, Detection accuracy: ±25 mV (0 to 60°C)

4.325V,

2.0 V,

Detection accuracy: ±35 mV (0 to 60°C)

Detection accuracy: ±50 mV (0 to 60°C)

• Overcurrent detection function

Discharge overcurrent detection threshold

Charge overcurrent detection threshold

Short circuit detection threshold

70 mV,

-30 mV,

Detection accuracy: ±15 mV (0 to 60°C)

300 mV, Detection accuracy: ±20 mV (0 to 60°C)

• Temperature detection function

: With external NTC (10 k, B=3435) and 4.7 k resistor

Discharge inhibition temperature: detection 70 °C or higher, release 65 °C or lower

Charge inhibition temperature : detection -5 °C or lower/50°C or higher, release 0 °C or higher/45°C

or lower

• Detection delay timer built-in

Overvoltage/undervoltage detection delay time : 2sec

2^ndovervoltage detection delay time

Open-wire detection delay time

: 8sec

: 3.6sec

TEST MODE reduces each detection delay time as 0.1sec by controlling the TEST pin input.

• Three type of charge/discharge enable signal output/

Selected from CMOS / Nch open drain / Pch open drain (high voltage tolerant output)

• Detection voltages and detection delay times are modified by product code.

• Low current consumption (-40 to 85°C)

Normal operation state : 4.5 µA (typ.), 10 µA (max)

Power-down state

: 0.1 µA (typ.), 1.0 µA (max)

• Supply voltage

: +5 V to +25 V

• Operating temperature

• Package

: -40°C to +85°C

: 20-pin TSSOP

Note) This product is not intended for automotive use and for any equipment, device, or system that requires a

specific quality or high level of reliability (e.g., medical equipment, transportation equipment, aerospace

machinery, nuclear-reactor controller, fuel-controller, various safety devices). If you are not sure whether

your application corresponds to such special purposes, please contact your local ROHM sales
