Battery Analyzer

Dear sir,We want to design a Battery analyzer for automotive purpose. The range of battery voltage can be 9V to 36V. Can you please suggest me an appropriate part number or reference design.Regards,Manoj HiwarkarEmbedded Engineer,9916707384 / 8087764...

We have designed in several LD56100 3.3 V LDOs. The datasheet specifies that the ESR of the output cap must be 3 to 300 mOhms. Over what frequency range is that required?

How to choose a proper MCU for DC fast charger ?

The interface between the Power Control Unit and the Control Unit is via CAN bus and the interface between the Communication Board and the Control Unit is via MQTT.Thank you for your time!

BLDC motor speed control using PID

HI all,I am trying to implement PID algorithm to control speed of bldc motor. For that the RPM of the motor is measured using Hall sensor. Now I have to write the code for pid can anybody tell the logic or example!I have studied about the PID control...

L5973D - 100% Duty Cycle Not Working

Hi,I have an L5973D set up for 28.5V output from 30V ish input for 2A current. The design requires the regulator to go to 100% duty cycle when the input voltage drops. At low currents (up to 1.5A) the device behaves correctly and smoothly transition...

Hello ST At what update rate can dither be applied to the onboard 4 bit DACs of the STLUX385A power management ICs? Is there any internal filtering on the output of the DAC prior to the analog comparator stage? best regards, Craig MacKinnon

Hi, I have a problem with 2 P/N LF33CV : they don't work properly. The output voltage is 7,8V. I have tried 2 LF50CV instead and no problem, the output is 5.0V A problem with that component ?

power mosfet without body diode

Hello we need a power mosfet without body diode for bidirectional applications . Is there a power mosfet like above? as well as is there a mosfet that has substrate Pin available? Sincerely mohammad maghsoodi

How can I configure BQ78350-R1 using STM32 with SMBus communication?

Selecting SPV1040 for energy harvesting from solar cell

Hi,This is John from Qmax Systems, We are designing a product - energy harvesting from solar cell. Our application requires a boost converter to convert 0.5V to 4.2V with an output current of min 100 mA. Do you think LTC3105 will support this applica...
