ML5232 Datasheet | LAPIS

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 m V (max) Overvoltage release threshold/accuracy : 3.90 V ±30 m V (max) - Integrated detection delay timer Overvoltage detection delay : 2 sec Overvoltage release delay : 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 : 2.5 µA (typ), 8µA (max) Overvoltage state : 4.5 µA (typ), 15µA (max) - Supply voltage : +7 V to +80 V - Operating temperature : -40 °C to +105 °C - Package : 20-pin TSSOP - Application - Power tools and Garden tools - Cordless Cleaner - E-Bike and Electric assisted bicycle - Uninterruptible Power Supplies (UPS) - Energy Storage Systems (ESS) - Part number ML5232-001TD 1/17 - Block Diagram V14 V13 V12 V11 V10 V9 V8 V7 V6 V5 V4 V3 V2 V1 Cell Selection Switches Voltage Regulator Clock Generator Clock Stop Detector Reference...
