Overcurrent Monitoring IC For Multi-serial-cell Pack S-8269B Series

The S-8269B Series is an overcurrent monitoring IC for multi-serial-cell pack including high-accuracy voltage detection circuits and delay circuits.
By using an external overcurrent detection resistor, the S-8269B Series realizes high-accuracy overcurrent protection with less effect from temperature change.

The S-8269A series with CTL pin is also available. For details, please contact our sales offices.

Features

High-accuracy voltage detection circuit
Discharge overcurrent detection voltage 1: 0.0030 V to 0.1000 V (0.5 mV step) Accuracy ±1.5 mV
Discharge overcurrent detection voltage 2: 0.010 V to 0.100 V (1 mV step) Accuracy ±3 mV
Load short-circuiting detection voltage: 0.020 V to 0.100 V (1 mV step) Accuracy ±5 mV
Charge overcurrent detection voltage: −0.1000 V to −0.0030 V (0.5 mV step) Accuracy ±1.5 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary)
Discharge overcurrent control function
Release condition of discharge overcurrent status: Load disconnection
Release voltage of discharge overcurrent status: Discharge overcurrent detection voltage 1 (VDIOV1)
High-withstand voltage
VM pin and CO pin: Absolute maximum rating 28 V
Low current consumption
During operation: 2.0 μA typ., 4.0 μA max. (Ta = +25°C)
Wide operation temperature range
Ta = −40°C to +85°C
Lead-free (Sn 100%), halogen-free
