VND7140AJ-E Max current
Posted on June 08, 2016 at 11:29Hello All,i have a question about the VND7140AJ-E which i have incorperated into a design of our company. I read the datasheet several times, because the maximum current of the chip is not really stated as such, just ...
VNH7013XP-E H-Bridge Datasheet Questions
Posted on January 13, 2017 at 02:26I am having difficulty discerning information from the datasheet.1) Where can I find additional information on this IC? (Other than the OrCad Model and Application Sheet.)2) What voltage can be used to activate/tri...
PWM generation using STM32F051R8T6 for Inverter application
Posted on February 05, 2017 at 10:46We are using microcontroller STM32F051r8t6 for one of our application. We are currently working on power inverter using microcontroller. To drive MOSFET bridge we are generating PWM signals which are given to MOSF...
How to prevent the L298 from heating?
Posted on February 03, 2017 at 11:30Hello, I am using L298N motor driver in parallel mode.But while running the motor L298N IC heats too much and suddenly stop. Motor specification are as follows:- Voltage=12V, Stall current=50A, Rated current=5A. C...
Timing capacitor of L6699
Posted on February 03, 2017 at 11:05Hi, everyoneI encounter a problem about L6699.The sch of L6699 is shown as below.I'm testing in open circuit, so thePC817 is open and all other parameters as shown in the figure.1.The delay is disabled.2.STBY(I'm ...
STPM01 STPM10 STPM34 Zero Crossing Signal (ZCR) latency
Posted on January 22, 2017 at 16:34What is the ZCR signal latency with respect to the line voltage for the STPM01 or STPM10?Is the ZCR delay really 5ms for the STPM32 family with respect to the line voltage?thanks,Bruck#stpm34 #stpm10 #stpm33
Is a daisy chain possible with two L9826's?
Posted on February 02, 2017 at 17:01Is it possible to connect two L9826 relais drivers in a daisy chain configuration or do I need to connect them in parallel with two NCS lines?
Resolved! L6480 bootstrap charge pump stop after write of configuration register
Posted on January 23, 2017 at 11:35The L6480 controller charge pump frequency stops after a write to the configuration register. A pulse on the reset pin seems to do nothing at all. Is there a proper sequence to restart the charge pump frequency? Ho...
Resolved! L6472 Stepper Driver Layout Question
Posted on January 26, 2017 at 16:29I notice that the EVAL6472 is a 4 layer PCB. Similarly, sparkfun has an evaluation board for the L6470 that is also a 4 layer PCB. My question: Is there some significance or layout best practice that requires a ...
