Part Number: BQ24075 Hi Power Management Gurus
A previous post of mine on the BQ24075 refers. The only way I managed to solve the problem was by connecting a 10k resistor between NTC and the supply. See schematic below:-
I am now challenged with…
Part Number: BQ24075 Hi
could you help check below BQ24075 schematic and any need to adjust ?
Design Requirements
• Supply voltage = 5 V
• Fast charge current of approximately 500 mA; => RISET :17.8K ohm
• Input Current Limit =1A;=> RISET…
Part Number: BQ24075T Other Parts Discussed in Thread: BQ24075 , Hello Forum,
The only mention of BQ24075T in the specs is on page 6 where the difference between BQ24075 and BQ24075T is the method (voltage vs current) of monitoring the battery temperature…
Other Parts Discussed in Thread: BQ24075 THIS IS AN URGENT CASE: We are using BQ24075 chip in one of our projects, but we are having battery charging issues. We are using lipo battery with the following specifications: 2400mAh, 3.7V , 8.9W. The battery…
Part Number: BQ24075 Other Parts Discussed in Thread: BQ25155 , Our device normally runs on line power, but we want it to continue to operate, in the event of a power outage, for a fairly short period of time to continue to gather data. So we are trying…
Part Number: BQ24075 Hello,
I want to use this formula in order to choose Riset for my app. But i want to know how to calculate Viset? or what is the min and max rande of Viset? There is no information about it in Datasheet.
Thank you
Part Number: BQ24075 Dear community
I have designed a Li-Ion charger with the BQ24075 based on the schematic below.
Problem: When I connect a voltage at IN (5V, current limit >2A), the LED at the CHG pin is illuminated, but the battery is not charged…
Part Number: BQ24075 Greetings,
I'm using a BQ24075 along with a BQ27441 to manage a 6600mAhr LiPo cell. Everything appears to be working correctly, except that when charging, the charging current cuts out after a few seconds, and then takes about 8…
Part Number: BQ24075
When the system is powered off, VBUS has power, Vdd and Vout have no power. I found that BQ24075 does not charge the battery, but when the system has power, that is, VDD can only be charged. The schematic diagram is as above, please…
