Part Number: BQ24035 The IC BQ24035 is powered by AC adapter of 5V, but the OUT (pin 15,16,17) is same voltage with input voltage. Seems it is internal Q2 is closed so that the charger IC cannot charge the battery. Please give me the suggestion.

Hi.
Could you please help me with some doubts about the "Charge Control Operational Flow Chart" on page 19 in the BQ24035 datasheet.
As I understand, VI(OUT) represents the voltage at the OUT pin, and VI(BAT) represents the…
Part Number: BQ24035 Hello,
My schematic is setup like the EVM with the following settings: ISET2 pull-up to USB input, PSEL pull-down to GND, CE pull-up to USB input, ISET1 1K to GND, TMR 60.4K to GND, DPPM 37.4K to GND, 10 uF caps on BAT and USB inputs…
Part Number: BQ24035 Other Parts Discussed in Thread: BQ24160 Hi everyone,
Reading the datasheet for the BQ24035 (Specifically the bq24032ARHLR) and it's 4.4V regulated voltage output when plugged into an AC adapter one question arises;
Q1 is…
Other Parts Discussed in Thread: BQ24035 Hi,
I am using BQ24035 EVM to test 3.7V li-ion battery charging.
When i connect fully discharged battery (2.5V) to EVM, it is not charging (EVM's VOUT is loaded with 10Ohm Resister and V LDO is open)
When…
Other Parts Discussed in Thread: BQ24035 I have a customer that is working on a predicted MTBF calculation and needs to model the failure rate of the BQ24035. Do you have a FIT number (failures per billion hours) for this part? If that number is not available…
Hello Ryuji
OVP:
The USB recommended max input voltage is 6V with absolute max of 7V.
Max AC input is 16V with absolute max of 18V
The bq24035 has AC input cutoff protection, at 6.4V the AC input FET will disconnect input.

Other Parts Discussed in Thread: BQ24035 , BQ27510-G2 Hello,
I intend to use in my circuit the bq24035 charger and the bq27510-G2 gas gauge. Both of the components have an input for the thermistor in the battery pack, what is the best way to use the…
Bob,
You are correct in that the BQ24035 will not "totally" shut down when the CE pin disables the chip. It was designed to intelligently manage the power sources that are available so that there would always be at least one source of power available…
I need a clarification / some reassurance regarding bq2403x and its standby feature (CE pin). Note: I do not own an EVM.
I have a use case where there may be no battery connected; in which case I would like USB or AC to be powering the system through…
