I HAVE A CIRCUIT WITH BQ24172 AS CHARGER & ACFET& RBFET P.N CDS17309Q3.
I have designed this board mainly based on BQ24172EVM-706-15V board .
I HAVE NOTICED THAT 30% OF THE MANUFACTURED CARDS HAVE A PROBLEM OF POWER THAT…
Part Number: BQ24170 Other Parts Discussed in Thread: BQ24172EVM-706-15V Hi experts,
Below is the schematic. I found, when the 4.2V x 2 cell battery is abcent, the system voltage is unstable after I changed the input voltage from 12V to 9V. The back-to…

Hello,
We are using BQ24172RGYR IC in our design to charge 7.4V 13500mA Lithium Polymer battery.
The input voltage is 12VDC and input current is set max to 1.6A (ACSET) but its only using 1.3A during charging.
The battery charging…
Hello, I tried modifying the example code to use VREFHI also for VREHI, the MCU must have 5V thus is have connected the jumper accordingly.
While using DACOUTB (through example code) at pin 70 of launchXL-F28379D, I am not able to receive any output.…
Sir,
I don't know the serial number for that product.
I doubt how to calculate the switching frequency of MOSFET driver ic I think if you can help me. and I mention below on all parameters for the driver ic.
9A High-Speed MOSFET Drivers

Part Number: TPS2662 Other Parts Discussed in Thread: LM2622 , LP2951 , TPS7A3401 , TPS1663 , TPS1653 Although TPS26601 operate 5Vin and 63mA, /FLT pin output is asserted.
I referred below application note and add current limiting resistor: 3kΩ, but /FLT assert…
Hi Kunal,
Thanks for your response.
I have trouble on filling design calculator. For parameter Rlstart, as our load is not linear, I have no idea how to define the R.
The load is 2 DCDC switching converter which further convert the 12V output from eFuse…
