Part Number: BQ24640EVM Other Parts Discussed in Thread: BQ24640 , Tool/software: Hello, My customer plans to use BQ24640 and is evaluating BQ24640EVM. They would like to put gate resisters for the external FET Q4 and Q5 somehow. How those gate resistors…
Part Number: BQ24640EVM Hi,
I have using BQ24640EVM to charge 1S 3.8V supercap, but seems something wrong cause can't normally charging.
I have change R14 to 82k let Vout = 3.822V. Below is EVM setting, Would you please help us check if anything wrong…
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…

Part Number: BQ24640EVM Other Parts Discussed in Thread: BQ24640 , Could anyone please share BQ24640 EVM circuit diagram for supercapacitor charging or any tutorial for setting up the charging module. The charger and evaluation module datasheet are bit…
Other Parts Discussed in Thread: BQ24640EVM , BQ24640 Hello, bq24640EVM charge current is 2A(min) on User's guide P.3. Could you please let me know this reason ? Since Viset range is 0V~2V and we can use external voltage for Viset, I think that we can…
Hi,
From the EVM Data Sheet(Last Page): "It is important to operate this EVM within the input voltage range of 18 V to 22 V and the output voltage range of 0 V to 18 V . Exceeding the specified input range may cause unexpected operation and/or irreversible…
Part Number: BQ24640 Hi TI,
I have been trying to build a basic BQ24640 charger for a single 2.7V 330F supercap. I am trying to reach the advertised 10A charging current. My circuit replicates the circuit from the eval board https://www.ti.com/tool…
Part Number: BQ24640 Hello,
i tested with the BQ24640EVM my configuration to charge 5X10F SuperCaps. A requirement that i can´t reach is to fully charge within 3 seconds. It takes 17s to be fully charged.
My input current reaches maximum after 17s…
