Hi Anthony,
I test it and it work, but this is not the best solution.
I test the circuit with IRLML2502 and AO3400A. they need at less 1V on GS, so out put voltage drop to 3.4V while bq24070 out put voltage is 4.4V.
So This did NOT resolve my issue…
Part Number: BQ24070 Other Parts Discussed in Thread: BQ24074 , , BQ24072 Hello Expert,
We would like to set cold temp -10 degree & hot temp 60 degree. And when temperture hit the threshold charger will stop charging. like bq24074 Battery Pack Temperature…
Part Number: BQ24070 I am using the BQ24070 to charge a Li-Ion 3.7V battery. The Stat1 output will normally blink an LED (~1.5Hz) when I apply external power with the battery absent. I have a handful of units that the Stat1 output stays low all the time…
Part Number: BQ24070 We have a unit that is using the BQ24070 charger on it set to charge at 1.5A. We realized we put an incorrect resistor down on the timer set pin so that all of our units were entering a timer fault condition too early. Once we changed…
Part Number: BQ24070BQ24070 has a problem, DC_VIN is 0V, using 3.7V lithium battery, when BAT to 3.2V, Vout will fall to 1.6V.What caused this? Is it normal?
Part Number: BQ24070 Hi
I have a query need your help.
when in supply mode does Q2,Q1 will open, if Q1,Q2 open the IN pin will have the output voltage.
Waiting for your reply.
Thanks

Part Number: BQ24070 “The peak system load is < 1.1 Amps
The load at startup is around 750 mA
The battery and the PCB is used to power a microprocessor system , so the load depends on the processing performed by the uP. On average during normal operation…
Hello,
I actually meant a scope capture on an oscilloscope of the BAT pin of the BQ24070. That would be helpful in diagnosing what's going on with the device.
Part Number: BQ24070 Hello! 1. Please can you help me to check my schematic and understand BQ24070 behavior in charge termination mode? The problem is charge termination status is not activated for hours (checked for 10h at least) on fully charged battery…
