Part Number: BQ25720 Other Parts Discussed in Thread: BQ25710 Tool/software: What happens to any pre-programmed configuration settings after the BQ25720 is power cycled, i.e. VBUS removed and then re-applied ?
Part Number: BQ25720 Tool/software: In our design, we have two PCBs: one with the BQ25720 charger IC and the other with an STM32 MCU.
We’ve encountered an issue where disconnecting the BQ25720 PCB appears to cause the I2C pins on the charger to short…
Part Number: BQ25720 Tool/software: So we are seeing an issue with the BQ25720, we are using BQ Studio to set various parameters, including the 'Host Programmed Input Current', IN_HOST.
When we change this and power cycle and start tests we discover…
Hi Tiger,
I have tried using the BQ25720 Eval kit over the last few days and this seems to do exactly what we want! When no battery is connected we need the input voltage to pass through the circuit to VSYS.
Our circuit is a copy of the Eval kit (recommended…
Part Number: BQ25720 Other Parts Discussed in Thread: TPS25751 , BQ24401 , BQ25792 Tool/software: Hi, how can we configure the BQ25720 to charge NiMH cells? The product spec says it supports NiMH chemistry among others, but the data sheet doesn't mention…
Part Number: BQ25720 Tool/software: To avoid PROCHOT triggered.
TI AE suggest
If the customer don’t like PROCHOT triggered, they can unmask this event, set PP_INOM=0. Register 34, bit 4.
There is another fault triggered, STAT_VDPM bit, need to…

Part Number: BQ25720 Tool/software: Hi, I have based my design on https://www.ti.com/tool/PMP22419 .
This uses a 1.5uH inductor, my calculations suggest a larger inductance is needed.
In my design, the Vin is supplied by USB-C 3.0 at 5-15V @ 3A and 20V…
