Part Number: BQ24600 Hi
The customer design with BQ24600.The precharge current is 0.09A and can be charged normally.
The problem is that the status pin output is occasionally unstable during charging and will output a square wave, and the frequency is…
Part Number: BQ24600 Hi
I have a query need your help.
The BQ24600 is set to charge at 0.9A, and the precharge current is 0.09A (the manual mentions that the minimum precharge current is 125mA). Will charging at 0.9A cause the status pin to report a fault…

Part Number: BQ24600 Hello guys,
One of my customers is evaluating BQ24600 for their new products.
At this moment, they have the following question. Could you please give me your reply?
Q. In their evaluation, BQ24600 and the external MOSFET got hot. Could…
Hello Parth,
Parth Patel said: No i did not try to toggling CE Pin( Can you suggest the how can i do this?)
I recommend adding a jumper between the VREF pin and CE pin, disconnect CE from VREF when the stat pin starts to toggle. Drive CE to GND, then drive…
Hi Aya,
When you say "Voltage drop from cables", do you mean the cable from the BQ24600 to the battery, or the cable from the buck-boost converter supplying power to the BQ24600 and the BQ24600? Note that the Buck-boost converter and the BQ24600…
Hi Henry,
The BQ24600 EVM uses a 1/4W 1206 resistor (the more surface area, the more heat it can dissipate and the larger amount of power it can handle).
See thread for more information on VCC resistor power ratings : https://e2e.ti.com/support/power-management…
Hi Star,
Thank you for your patience.
I checked the schematic and I am unable to pinpoint the issue. Could you provide more information on when you observe this behavior?
1- What are the test conditions?
2- Could you capture a waveform of the switch node…
Part Number: BQ24600 Is it possible to turn this IC into a galvanically isolated charger, without adding another switcher?
That is, i want the supply voltage to be galvanically isolated from the charge-current at the cell.
