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.

Hi
I just design board base on evm board and I have issue the VREF is zero volt, so charging never starts. Vout is working fine and even when you unplug the power supply (Running on battery)
below is my schematic, please let me…
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…
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 IC gets thermal shutdown for VCC of 18V current of 35mA,but actual Tja is 53 degrees per watt,according to that raise is 34 degrees.Is there any other reason for thermal shut down.
Part Number: BQ24616 The charge controller is blowing up for unknown reasons. See attached schematic of the charge controller. The system load is directly connected to Vbat. Note: we have since determined that Vr for D6 is only 10V. However, it is uncertain…
Part Number: BQ24616 Hi team,
My customer is trying to determine what they should be setting VLOWV at, in the datasheet there is a min and max recommmended voltage but isn't this spec programmable/settable? Can you help to explain what value it should…
Part Number: BQ24616 Hi team,
Is there a way that this feature can be bypassed? My customer doesn't need the feature and says their battery doesn't have a thermistor on it, so they don't plan to use the internal temp safety feature of the chip.…

Hello everyone
I have recently designed a charge controlled for a 3-cell Lithium-Ion battery using the BQ24616. Apon testing the board, I noticed that the current that the battery charges at is much lower than it was designed. The…
