[L6472] 1.3A output when power on without chip init
Posted on May 12, 2016 at 04:51Hi,We got a problem for L6472 chip when power on, the H-bridges is ON with default current output at 1.31A while the /STBY\RST=VDD and SW = 0V states. However, when the /STBY\RST=VDD and SW = VDD, the H-bridges kee...

STripFET F7 Negative Vgs Voltages
Hi Everyone, I am using the STL120N4LF6AG device in a product and I was wondering if there is any have to turning it off with a negative Vgs voltage? The data sheet only lists a positive Vgs limit (40V) so it is unclear what it's tolerance to a negat...
How to wake up Li-ion battery that has entered over-discharge protection?
I am using a STBC08 to charge the battery in my application. It works fine, but if the battery isn't charged for a long time the battery goes into over-discharge protection. In this state the battery terminals are at 0 V and trying to charge the batt...
Driving Multiple Sensored BLDCs
I have a project where I would like to drive two separate sensored BLDC motors with a single microcontroler. The only options I have seen involve the control of a single motor with no options of stacking shields (in the Nucleo's case) or using mu...
Software related to EVAL-L9907 and SPC560P-DISP
Hello,Just received an EVAL-L9907-H and a SPC560P-DISP, I'm looking to loadup basic examples or related software. I see lots of PDF's referenceing a GUI, though I'm having a tough time tracking down real software to use with this eval kit. Any help i...
Precharge bootstrap capacitor for three phase inverter(MOSFET based)
I want to switch the low side mosfets in a particular manner to charge the bootstrap capacitor in driver IC. I wanted generate three 120 degree phase shifted square pulses of same frequency. Can three phase shifted signals be generated by timer in MA...
IHM02A1 L6470 muliple Boards
Posted on December 01, 2017 at 17:25Hello,I currently try to use more than one Stepper Motor Controller Board (3 to be precise) stacked. Every single one is working perfect with individual CS jumpers set by using the standard library from st - using...
RHFL7913 negative Regulator, Current programming
Hello ST,In the process of testing the RHFL7913 device, I would like to program the current limit for the device. Though datasheet says device is internally programmed to 4A. I would to reduce the current capability to 2A by placing the resistor ( i...
