Part Number: BQ24616 Hello TI experts,
My customer tests BQ24616 in their own PCB, and they found one problem.
Here is some conditions of fault situation.
1. they attached battery to a charger first, and apply VIN (DC adapter, 12V)
2. and they could see…
Part Number: BQ24616 Hi Experts,
Our customer designed a custom board referencing the EVM schematic however, the resulting board does not charge the 8.4V 2 Cells battery.
Here is the customer schematic:
Can you help with this?
Thank you.
Regards,
Marvi…
Part Number: BQ24616 Hi
The customer design with BQ24616. When disconnect the battery, PH has no output. Stat1 light is on, stat2 light is off, PG light is on.
Attached the schematic and waveform.

Please give…
Hello,
The below is excerpted from the Section 10, "Power Supply Recommendations:"
"For proper operation of bq2461x, VCC must be from 5 V to 28 V. To begin charging, VCC must be higher than SRN by at least 500 mV (otherwise, the device will…
Dear Lorand,
Can you please confirm the current rating? I am confused as to what is meant by the unit "A-s."
Has the phenomenon been repeatable? What was the charge voltage of the batteries when this happened? Do you have any observations when…
Part Number: BQ24616 Dear Expert
As shown below, the circuit designed according to the reference design does not charge properly.
The S-terminal of Q1 has no output, and BAT+ has no voltage. STAT1 is orange.

Part Number: BQ24616 The charge controller is failing or blowing up even after showing proper charging operation. See attached schematic of the charge controller. The system load is directly connected to Vbat. The downstream load is two buck converters…
Part Number: BQ24616 We have inherited a design from another design firm.
We have recalled units with broken chargers. Closer inspection reveals that the BQ24616is failing. Sometimes it has a hole through the IC.
Most notably, the PH and sometimes the…
