ML5232

Overvoltage Protector for 14-Series Cell Li-ion Rechargeable Batteries

◼ General Description

The ML5232 is an overvoltage protection IC for 14-series-cell Li-ion rechargeable battery packs. It asserts the

"L" level on the N-channel open drain alarm output and the "H" level on the CMOS alarm output if overvoltage

condition is detected on any single cell.

◼ Features

• 14-series-cell high-precision overvoltage detection

Individual cell monitoring performed

Fewer cells supported by shorting cell inputs.

Overvoltage detection threshold/accuracy : 4.35 V ±20 mV (max)

Overvoltage release threshold/accuracy

3.90 V ±30 mV (max)

• Integrated detection delay timer

Overvoltage detection delay

Overvoltage release delay

2 sec

0.2 sec

Overvoltage detection and release delays are reduced to 0.1 sec in the customer test mode

• Dual overvoltage alarm outputs

Both the OVN pin (N-channel open-drain) and the OV pin (CMOS) are available for overvoltage alarm

output

• Externally-controlled overvoltage alarm

OVN and OV alarms enabled by the CTRL pin input

• Variety of overvoltage thresholds and detection delays can be redefined and supplied as code products

• Low current consumption

Normal operation state

Overvoltage state

2.5 µA (typ), 8µA (max)

4.5 µA (typ), 15µA (max)

• Supply voltage

+7 V to +80 V

-40 °C to +105 °C

20-pin TSSOP

• Operating temperature

• Package

◼ Application

・Power tools and Garden tools

・Cordless Cleaner

・E-Bike and Electric assisted bicycle

・Uninterruptible Power Supplies (UPS)

・Energy Storage Systems (ESS)
