Part Number: BQ24640EVM Other Parts Discussed in Thread: BQ24640 , Hi, a design of the BQ24640 has been made to charge 8 supercapacitors of 70F to 22.6V, and then has been implemented on the BQ24640EVM evaluation board.
The design has been tested and indeed…
Part Number: BQ24640 Hi - I've got a strange problem with the PG output.
First, the datasheet defines PG thus: Open-drain active-low adapter status output. Connect to pullup rail through LED and 10-kΩ resistor. The LED turns on when a valid is detected…
Part Number: BQ24640 Can we use BQ24640 to charge supercapacitor (3000F each) bank having 9 capacitors in series or is it only to charge a single supercapacitor?
Also is it possible to use this IC to charge it at 20A current (Datasheet value is 8A) in…
Part Number: BQ24640 Hi Experts,
Our customer is wondering about table 4 of the data sheet, and the ability to optimize these parameters when the sense resistor is changed. And if this inductor is part of the efficiency calculation within the system. …
Part Number: BQ24640 Hi Experts,
Please advise to the query from Cx:
I am currently planning to use the BQ24640, which I know is designed for high currents, but is able to charge at lower currents by changing the sense resistor. I am trying to determine…
Part Number: BQ24640 Other Parts Discussed in Thread: TLV840 Hi - I'm trying to finish a bq24640 design but...
The datasheet table 2 says STAT goes on (OC low) when CE is high and blinks on fault condition or CE off. Figure 7 shows STAT goes low and…

Part Number: BQ24640 Other Parts Discussed in Thread: BQ24620 , BQ25731
hi there,
my customer want to use BQ24640 as a supercap charger, and the charger current will be set in 16A. the BQ24620 EVM is only 10A (max). so could we modification Rsense and…
