Power management

i need to charge 18650 li ion battery using SPV 1050 MPPT IC. where will i need to connect the load (microcontroller)? on which pin do i need to connect my micro controller?

Do i need to connect my load on STORE pin or in parallel to VBATT+ ?In STEVAL-ISV020V1 what is EXT_SUP? is this where i need to connect my loadwhat will happen if i discharge 1 Amp current from 18650 battery?what is the current capacity of inbuilt P...

Hi, IC L6564 O/p voltage 24VDC is fluctuating .

HI, We are using IC L6564 for application of AC to DC power supply 24VDC/1.5A . But We are getting fluctuating output vltg in between 20V to 24V without load .When 1k load is connected then output drop down & we get 13Vto 15V.

L9963 BMS IC Programming Document and other informations

Hi ST,I am interested In using the L9963 IC for UPS battery management system.Since it is a UPS, i am not intending to use the default SPC574S64E3 but another STM32 MCU.The following are my questions:Is there any Programming Manual for the L9963 IC a...

STSPIN32F0601TR's number of GPIO

HelloI want to ask about STSPIN32F0601TR.I'm reviewing the IC for motor controller, in datasheet it describes the number of GPIO 21.but counting the number of port N. Name Type Function1 PB8 I/O - FTf MCU PB84 PC13 I/O - TC MCU PC135 PC14 I/O - TC MC...

For POWERSTEP01 is it possible to tell what the maximum speed of my stepper motor in VOLTAGE mode could be.

I am using a POWERSTEP01 at 48V in VOLTAGE MODE.Here are the motor parameters. Also does this calculator assume a 0.9 degree stepper motor?Is there an inherent speed limit (microsteps/sec) for VOLTAGE MODE?Why is CURRENT MODE capable of higher speeds...

I am trying to do laser engraving with a POWERSTEP01. But I get high frequency oscillations on my motor.

I am in current control mode, and the stepper motor is using about 3 amps.Is there anything I can do to reduce these oscillations.Also note that the white line is about 0.010" thick.I am using x16 microstepping, and I currently have 1600 microsteps p...

We are using STC3117 Fuel Gauge. Can we read a configured RAM data from one device and write the same RAM data to another device and if yes how??

We are using STC3117, and we are performing a charge and discharge cycle to avoid any battery fluctuation issue so if we need to do it with mass number of device, it is not possible to perform same task so can we perform this in a device and get RAM ...

Can we remove VSS power from 8 daisy chained L6470s but keep them powered by 1 external 3.3VDC supply via the VDD pins (ref. section 1-3 of ST Micro note AN4241) w/o damaging the parts? Will the L6470's retain their parameters w/o VSS but with VDD on?

Hi, I am using STPM32 with Rogowski coil, Can I use antialiasing Filtering (Double RC pole) from Coil to IINP and IIN? Thank you

viper222 design help

as shown in pictures datasheet and e designsuite both have different pin names for the same ic viper222 can anybody help regarding this topic please.thank you
