ON Mode/Selfdiagnosis
Electrical Characteristics
When the PD_N-signal goes from low to high, the self diagnosis of the ATA6871 starts. During
this self diagnosis the following tests are performed:
If self diagnosis fails, the STATUS of the lowest ATA6871 is constant low. If the self diagnosis
succeeds, the STATUS of the lowest ATA6871 is toggling.

• Test if over/undervoltage or overtemperature comparators are able to switch or if they stuck to
• Test if pins OROUT_IN, OROUT in stacked ICs are able to switch or if they stuck to 0 or 1 and
• Test if pins STATUS_IN, STATUS are able to switch or if they stuck to 0 or 1 and if the
• Detect open or shorted input pins MBAT1 to MBAT7
• Detect wrong setting of CONF0, CONF1 (e.g. 4 cell configuration programmed, 6 cells used)
