8.3.8.3 Interrupt to Host (INT)
In some applications, the host does not always monitor the charger operation. The INT pulse notifies the host on
the device operation. The following events will generate a 256-μs INT pulse.
Good input source detected
VBUS above battery (not in sleep)
VBUS below VACOV threshold
VBUS above VPOORSRC (typical 3.8 V) when IBADSRC (typical 30 mA) current is applied (not a poor source)
Input removed
USB/adapter source identified during Input Source Type Detection (IINDPM Threshold).
Charge Complete
Any FAULT event in REG09
VINDPM / IINDPM event detected (REG0A[1:0], maskable)
Top off timer starts and expires
REG09[7:0] and REG0A[6:4] report charger operation faults and status change to the host. When a fault/status
change occurs, the charger device sends out an INT pulse and keeps the state in REG09[7:0]/REG0A[6:4] until
the host reads the registers. Before the host reads REG09[7:0]/REG0A[6:4] and all the ones are cleared, the
charger device would not send any INT upon new fault/status change. To read the current status, the host has to
read REG09/REG0A two times consecutively. The first read reports the pre-existing register status and the
second read reports the current register status.
8.3.8.4 PMID Voltage Indicator (PMID_GOOD)
In BQ25619, the accessory devices can be connected to charger PMID pin to get power either from adapter
through Q1 direct path or from battery boost mode. An optional external PMOS FET can be placed between
charger PMID pin and accessory input to disconnect the power path during over-current and over-voltage
conditions. PMID_GOOD is used to drive external PMOS FET. PMID_GOOD HIGH turns on PMOS FET, and
PMID_GOOD LOW turns off PMOS FET.
Upon adapter plug-in, PMID_GOOD goes from LOW to HIGH when VBUS rises above battery but below VACOV,
and passes poor source detection. During the operation, PMID_GOOD will go from HIGH to LOW if Q1 current
exceeds 115% of the IINDPM threshold. (IBLK_OCP), or adapter voltage rises above 5.8 V (VBST_OVP).
High voltage adapter over VBST_OVP will keep charging the battery if all conditions are valid. The external PMOS
FET will stay off to protect the accessory from over-voltage fault.
When adapter is removed, PMID_GOOD goes LOW before battery boost mode starts.
In battery boost mode, the device regulates PMID voltage between 4.6 V - 5.15 V as a stable power supply to
the accessory devices. PMID_GOOD goes from LOW to HIGH when PMID voltage rises above 3.8 V
(VPOORSRC ). Similar to adapter present scenario, PMID valid voltage range is between VPOORSRC and VBST_OVP.
Once PMID voltage is out of this range, PMID_GOOD goes LOW to disconnect the accessory device from PMID.
During boost mode, all the conditions to exit boost mode will drive PMID_GOOD from HIGH to LOW, including
boost mode disable in register, ACOV, TS fault, battery depleted (VBAT_DPL), BATFET over-current, (ISYS_OCP_Q4),
etc.
