Part Number: BQ41Z90 I would like to implement the PDSG FET circuitry for inrush current control. The datasheet gives a brief description on how it works but there are no details in the technical reference manual about predischarge.
I would have expected…
Part Number: BQ41Z90 Hello,
I read in the forum that the latest TRM is under NDA and not generally available.
Since our company has an ongoing (signed) NDA with TI, could we please get the latest TRM?
Is there any other more recent document / software…
Part Number: BQ41Z90 I am interested in using BQ41Z90 for a new design, but I am seeing the component is out of stock. I also see multiple threads in the support forum with others having the same experience with this component being hard to get. When…
Part Number: BQ41Z90 Hello everyone,
The question in the title came up while reading the Technical Reference Manual. It indicates that one should write a bunch of registers that are actually not present in the device.
There's no RSNS register. The…
Part Number: BQ41Z90 Hi,
Could you please let us know the expected production timeline for the BQ41Z90?
Additionally, while evaluating the device using the EVM, we noticed that some of the BQ41Z90 IC configuration and settings are not documented in…
Part Number: BQ41Z90 Hello,
From datasheet and TRM I can see the BQ41Z90 has an internal RTC that can be used to trigger wake up routines; however, there's no description of this RTC (Accuracy, drift over time, drift over temperature, ...).
Is any…
Part Number: BQ41Z90 Hello,
I understand the charge pump allows driving a high side NMOSFET by providing +10V higher than the PACK+ voltage. BAT+ voltage is 60V in my application. After DSG FETs are turned on, BAT+=PACK+=60V, and DSG=70V. I would like…
Part Number: BQ41Z90 Hello, We are using the BQ41Z90 as the battery pack manager in our application. The device is configured with NR = 0 and uses the PRES pin to detect system presence. The device will be SEALED in production, and the host MCU communicates…
Part Number: BQ41Z90 Hi TI team,
I am using BQ41Z90 to design a PCM for 8S1P battery.
I manage to connect each cell supply line by soldering on PCM.
so come out a question that if there is power-up sequence requirement for BQ41Z90.
Does it require…
Part Number: BQ41Z90 Other Parts Discussed in Thread: EV2400 we find a problem with BQ41Z90 that can not power up and communicate with EV2400. I attach schematic diagram.
we have succeed in communicating with EVT board. But fail in our PCM.
for now…
