Enquiring under-voltage lockout in Smart On/Off controller
I am planning to use a smart On/Off controller in my circuit. I have came across STM6601 (smart push button On/Off controller) which matches my requirements. The under-voltage Lockout seems to be done by comparing the input voltage with the internall...
VN750PS-E Status pin
Hi,Can you please tell me the function of status pin? Is this pin can be used as feedback pin and connect to mcu?If not used, what to do? In datasheet, table 2 is given for unused and not connected pins, but it is not clearly.
How to build a battery model for STC3117 in different temperature?
From the datasheet and AN4870, we understand that it is necessary to calculate the battery's internal impedance and measure the OCV table.After configuring CC_CNF and REG_VM_CNF, the STC3117 operates properly using its algorithm.The operating tempera...
L9963E in 12S setup, middle cell shows too low voltage
Hello!I have a L9963E in 192 cell EV battery setup, there's 16 modules daisy chained, each handling one 12S pack. The bottom module has a L9963T and stm32 chip that handles the whole pack and communicates with car through CAN bus. Everything is worki...
EVALSTDRIVE101
Hi everyone,for this driver I am seeing 700 ns sw deadtime also deadtime: 800. What is difference between them and which one is in use in application. Second question why it is 700 or 800 ns because according to Mosfet datasheet this values is too lo...
Resolved! STWBC86 and STWLC38 Adaptive Charging Circuit
Hi,We are currently testing the above chips.I have a few questions:Can I get information or documents stating how to download firmware using an external MCU and the reference design for that? We use 3.3V I2C communication, and I understand the ST chi...
ISO8200BQ RDS(on)
Dear All,I'm using the evaluation board STEVAL-IFP033V1 Galvanically-isolated 8 channel high-side driver based on the ISO8200BQ.I powered the board with 22.8VDC, all outputs on from the isolated side (all LEDS green on the output connector)I checked ...
L7987LTR only provides 0.5 A max current rather than 2 A.
Posted on November 05, 2016 at 19:04 Hi I would like to use L7987LTR in a few designs. The datasheet of the IC says its able to provide 2 A current however I can only measure 0.5 A. I have tested the schematics in 3 different layouts and l...
Resolved! STWBC86 FOD Reping behavior
I was recently testing the FOD reping behavior and noticed that when FOD is detected and FOD reping is enabled, the TX retry delay is fairly short (a few seconds).Are there any settings to increase this time delay?If a foreign object keeps getting de...
