• 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: VRIOV = VDD × 0.8 (typ.)
• 0 V battery charge: Enabled, inhibited
• Power-down function: Available, unavailable
• Alarm function
AO pin output logic: Active "L"
AO pin output form: CMOS output, Nch open-drain output
Connection when AO pin = "L": VSS pin, VM pin
• High-withstand voltage: VM pin, CO pin and AO pin: Absolute maximum rating 28 V
• Wide operation temperature range: Ta = −40°C to +85°C
• Low current consumption
During operation: 800 nA typ., 1500 nA max. (Ta = +25°C)
During power-down: 50 nA max. (Ta = +25°C)
During overdischarge: 500 nA max. (Ta = +25°C)
• Lead-free (Sn 100%), halogen-free
