Caution The combination of CTL pin control logic active "H" and CTL pin internal resistance connection "pull-up"
worsens the accuracy of overcharge detection voltage. Therefore, this combination can not be set up.
*1. CTL pin control logic active "H" / active "L" is selectable.
*2. CTL pin internal resistance connection "pull-up" / "pull-down" is selectable.
*3. CTL pin internal resistance value 1.0 MΩ / 2.5 MΩ / 5.0 MΩ is selectable.
*4. Discharge inhibition status latch function "available" / "unavailable" is selectable.
*5. 0 V battery charge function "available" / "unavailable" is selectable.
*6. Power-down function "available" / "unavailable" is selectable.
*7. Release condition of discharge overcurrent status "load disconnection" / "charger connection" is selectable.
Remark Please contact our sales office for the products with function combinations other than those specified above.
