Part Number: BQ24040 Hi.
I tried to charge a lithium-ion battery using the BQ24040, but it is not charging.
During this time, the /CHG pin was at a high level, and the /PG pin did not reach 0V, remaining at about 500mV.
When I removed the battery to troubleshoot…
Part Number: BQ24040 Hi,
I designed a product using the BQ24040. There is a possibility of IN and Vss shorting due to water exposure.
As far as I can see from BQ24040 Pin FMA , I don't think there will be any damage to the IC even if IN and Vss are shorted…

I have this square wave with 100ms period 50% duty cycle on ISET pin.
ISET has only a 1.8k resistor connected.
ISET2 is stable low (10k pulldown + powered down MCU giving 200mV on pin, ohmeter…
Part Number: BQ24040 Hello, I designed a circuit for lithium ion battery charging with the BQ24040. I tried to figure out why the battery does not charge but after some days of studying the data sheet and measuring the outputs I don't know how to solve…
Hi,
I moved the power meter at the power input pin BQ24040 and now the battery is charging at 1A and it works well. So the test setup was the problem.
Thanks for the support.
