PowerSTEP01, Sensorless Stall detection vs Overcurrent detection
I don't really understand how these two functionalities differ. One is measuring on both low side and high side, the other one only on low side.The available threshold values are the same in both cases.When would you use OCD_TH and not STALL_TH, and...
Resolved! VN9D5D20FN operating with Vcc 5v
Hello,We are looking to use VN9D5D20FN (SPI management and monitoring) as power distribution solution for our product. There are 4 channels which are fed from common output of a buck converter. The buck has 5V 3.2A max output and that goes into VN9D5...
Resolved! What is the maximum error of STPM32?
Hello,in the Datasheet of the STPM32 the accuracy of the active power is 0,1% error over 500:1 dynamic range.Is this the best case error or the maximum error of the enerqy measurement after calibration?What does the dynamic range of 5000:1 mean?
BMSWTXA - Eval Board
Hi, We have ordered the AEK$POW-BMSWTXA Eval board in hopefully testing it with our active battery balancing solution. I was wondering if anyone knows if this board can be used standalone without the need for a secondary MCU, and if there was any way...
Resolved! L7987L Not working as expected.
Hello everyone, In the link below I designed a DC/DC Buck configuration with the L7987L chip. We have used this chip many times but I needed to update the EMI performance so I reduced some loops on the layout side. Also removed the separate ground pl...
Resolved! L9788 Marking is 0D273, is it correct?
L9788 Marking is 0D273, is it correct?Please see the label photos and product MARKING AREAIs this the original？
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...
