BATTERY PROTECTION IC FOR 2-SERIAL TO 4-SERIAL-CELL PACK (SECONDARY PROTECTION)
S-8264A/B Series
4. Test Mode
In the S-8264A/B Series, the overcharge detection delay time (t
The test mode can be set by retaining the VDD pin voltage 8.5 V or more higher than the SENSE pin voltage for at least
80 ms (V1 = V2 = V3 = V4 = 3.5 V, Ta = 25 °C). The status is retained by the internal latch and the test mode is retained
even if the VDD pin voltage is decreased to the same voltage as that of the SENSE pin.
When CO becomes “H” when the delay time has elapsed after overcharge detection, the latch for retaining the test
mode is reset and the S-8264A/B Series exits from the test mode.
