Part Number: BQ25790 Hi team,
Could you explain the function of VBAT_OVP_MASK? What is the meaning of "INT", interrupt?
If I set VBAT_OVP_MASK=1, when VBAT OVP is triggered, will Charger stop charging?
Thanks and look forward to your reply! …
Part Number: BQ25790 Other Parts Discussed in Thread: BQ25792 We have a design with BQ25790, see attached schematic below.
Current problem is that when connect an expternal DC source (+12vdc) to BQ25790 it will trigger the flag VBAT_OVP_STAT=1h.
The voltage…

Hi team,
I know it is recommended that PROG resistor should be <2%. What is the maximum threshould? If using 1.5MHz & 2s, 6.04kohm is recommended.
If the determination is done by specific threshould in internal comparator…
Hi Jeff,
I understand BQ25790 BGATE response is good to minimize VSYS drop. Customer tries in actual evaluation. When customer wants to add protection on the VSYS drop, what solution can be considered?
Best regards,

Part Number: BQ25790 Hi team,
Our customer find they can not overwrite the IINDPM register, is that because the D+D- pin is floating? Or they need more delay time?
Please help to provide possible reason, thanks!

Part Number: BQ25790 Hi team,
Could you help to share why the temp of IC will rise at the end of charge, (VBUS=9V VBAT=8.8V), PFM enable.
Besides, this symptom only occur when VBUS=9V. It can not be reproduced when VBUS=12V.
Thanks!
Part Number: BQ25790 Hi ,
We are using BQ25790 in our Battery Charger circuit.
We have designed and ordered PCB and we have connected with Stencil manufacturer for stencil.
We have followed datasheet as below for solder paste opening on stencil.

Hello
Do you have any suggestion for suitable EMI filter for #1 (VAC1) as the primary input ( Vbus ) and the source #2 (VAC2) as the secondary input ( 12V DC) ?
I guess we need a differential filter only? Do you have any filter design…
