Part Number: BQ24074 Hello,
Quick question on the charge profile
Whilst plotting the charging characteristics we noticed that the charge seams to turn on and off is this normal ?
Just trying to understand what and why
The voltage and temperatures are…
Part Number: BQ24074 Hello, I am having a big headache with a charger circuit that I have design for my application. The circuit is presented by the circuit below.
The battery is reaching 4.4V and the charging current goes as low as 30mA (or even less…

Part Number: BQ24074 Greetings,
I have built the circuit in the schematic below and have problems with battery charging. None of the external status or EN pins are connected just for bench top testing.
When I have an external source and no battery connected…

Part Number: BQ24074 Hi
When my BQ24074 working on pre-charge mode, BAT pin(2,3) voltage is only 1.64V. I tried to remove the battery, the floating BAT pin(2,3) voltage is still 1.64V. Is this normal? Attached is my circuit diagram, please help to check…
After you mentioned the waveforms being abnormal, I ended up investigating the output ~4.4V from the BQ. It had a bit more ripple than I anticipated as well. After probing around a bit, I believe the issue I had was due to an interaction with a downstream…
Hi Luke,
Luke Yeh said: If the charging temperature control of BQ24074 is changed to BQ28Z610, it should be able to avoid the phenomenon of charging stop Luke Yeh said: BQ24074 HW OTP = charger suspend charging when the temperature is too high
Yes, this…
