Regarding availability of low side switches
Hi, Can you please let me know the availability status of low side switchesRequirements:Support more than 60V of battery Voltage and qualified for automotive application.Load Current should be up to 4ASupport over voltage and over current protection....
VND5E006ASP-E Max Voltage Output for CS pin
To confirm, the max output voltage on CS pin (I assume it is called VSENSEH) is 8V according to Table 8 on p11 (https://www.st.com/resource/en/datasheet/vnd5e006asp-e.pdf). But I assume this depends on the sense resistor and ISENSEH of 7mA. What is...
Resolved! Setting reference voltage with battery monitor li-soci2(3.6v) battery *Vrefint
hello everyone,In a battery-powered IoT project, I can never make accurate measurements because my battery voltage is the same as my reference voltage. I did not use any power ICs to reduce the cost of my project.I am using a 3.6V li-soci2 batterySav...
Resolved! L7987 ripple issue
HI Sir，we have two different results of the ripple noisebase on same PCBA design, but different L7987 origin:1. Mark of "ST e3 G9207，L7987， CHN 3L0"，ripple noise 2.2V 2.9KHzinput 24V， output 12V， load 5ohm 2.4A 2. Mark of "ST e3 7B658， L7987， PHL 037...
Resolved! STPS3045CPI Obsolete - Common cathode doubt
Hi,STPS3045CPI is now obsolete and STMicroelectronics no longer carries collateral support. I am wondering if anyone can help. I am looking thru old documentation but it is not clear to me whether the mounting plate on the top is connected to the com...
Resolved! STPM3x INT1/2 outputs - how to configure
hi,I am now familiar with the STPM3x programming, by using EVALSTPM33/34 boards.I have been able to do some basic low voltage testing where I receive interrupts on INT1 line on EVALSTPM33/4 for voltage swell before I try mains voltages.Then I run the...
Resolved! Use of powerSTEP01 in “voltage mode�?
We are developing an OEM board which is capable of driving bipolar stepper motors from 15 to 80Vdc 10A max, in voltage mode and current control. Our customers should be able to change the supply voltage (Vbus), operating mode (voltage or current), wi...
L4985
In my 750W PFC project, I've employed the L4985A PFC controller IC. I utilized the e-design suite offered by ST to design my PFC, and I fabricated the PCB using the components specified in the e-design file. Despite ensuring that all the necessary v...
Resolved! LDL212 undervoltage mode
Hi, can you tell me what happens to the LDL212 when the input voltage drops below the output voltage+dropout? Does it track the input voltage (minus the dropout voltage)? Or does it drop out? Also, in the datasheet it mentions undervoltage lockout in...
