Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
The VN5E050MJ-E is used as a over current protections devices. We monitor the current via the current mirror output and disable the device when the current reaches the preset threshold. The threshold is well below the max rated current of the devic...
HeySo I'm currently building a Solar charger for a 10000mAh Li-Io battery pack and I came across the SPV1040.For the project the charge current does not have to be high so the batterys are just slowly charging but I wanted to use Solar panels with ab...
Posted on January 15, 2018 at 10:45HiThe L6480 absolute position counter seems to count in multiples of 256 micro steps? When executing the move command with a 1000 micro steps or using the GoToDir command with a 1000 micro step value both generate ...
Posted on February 20, 2018 at 16:13The data sheet for the 6470 (and 6472) is not clear regarding the SPI clock rate. what is your take on this? the reason why i ask is that a clock rate was selected, boards were built and deployed. all was well. ne...
Hello all!We are using L6470 in our product for stepper motor control. We are using the SPI mode control with MOVE command.I would like to know the time (relative to given external clock) it takes to run the motor for given distance, given max speed ...
Hello, I am designing Stepper driver for NEMA17 motors which going to operate within range of 300RPM max. I am planning to use 42V to supply the motor and torque tests shows that 1A is sufficient to obtain the target. What I have noticed on the firs...
STEF01 has an interesting price but requires an external power MOSFET for reverse polarity protection. I see from the datasheet that ST has performed some measurements using external FETs, so which one would you recommend?NOTE: This question and answ...
We are using an ST1S12GR device and the input current is >2.5mA even with only the feedback loop connected and ENable pin connected to Vin. Feedback resistors values are 220k resp. 59k. According to Datasheet Table 8 (“Electrical Characteristics�?) Q...
