Part Number: BQ25856-Q1 Other Parts Discussed in Thread: BQ25756 Tool/software: Hello,
Is there a calculations sheet available for the BQ25856-Q1. I see there is one linked on the web page but it is for a different chip. Are these parts close enough…
Part Number: BQ25856-Q1 Tool/software: Hello,
Our design requirement is 24Vin, 14.4Vout battery charging current is 30A. Since BQ25856-Q1 supports 20A, can we connect another BQ25856-Q1 in parallel to archive 30A. Please share the reference circuit…
Part Number: BQ25750 Other Parts Discussed in Thread: BQ25856-Q1 Tool/software: I see (from related question) that by shorting SYS to VAC, BQ25750 can supply power from battery to input (VAC). I also see (from documentation) that once the voltage at VAC…
Part Number: BQ25856-Q1 Tool/software: I'm supposed to design a 4-switch Bidirectional DC-DC converter for client application. I should be able to charge and discharge the cell at a maximum of 360A peak current for 1s and 120A continuous. Is this a suitable…

Part Number: BQ25856-Q1 Tool/software: We're using the BQ25856 with supercaps to backup our main 18V power rail when the external 18V source goes away for brief periods. The supercaps are physically on a separate PCB, so during development and product…
Part Number: BQ25856-Q1 Tool/software: I have two applications: one for battery charging and the other for a DC-DC converter. To reduce the BOM, I am considering using the same IC for both applications. My DC-DC converter has the following parameters…
Part Number: BQ25856-Q1 Tool/software: Dear Team,
We are planning to design a backup power supply system for our vehicle. The EV battery will be 48V or 24V and the backup battery will also be 48V/24V with less capacity. We wanted to design a circuit…
Part Number: BQ25856-Q1 Tool/software: Hi,
Reading the datasheet it states:
"Input Voltage Detection and Power – Connect a 1-µF capacitor from pin to PGND. Pin 33 is the input bias to power the IC, and ACOV/ACUV resistor divider should be connected…
Hello yx yan,
Yes, the BQ25856-Q1 can bidirectionally charge batteries. The BQ25856-Q1 IC was built with this application in mind.
The BQ25856-Q1 will need an I2C command to enter into reverse mode and program the right output voltage/current.
Let…
