Power management

Hello! I have an STEVAL-ISV020V1 module. Is it possible to modify this module in order to charge a supercapacitor with a minimum voltage of 2.2V and a max. voltage of 3.8V?

From documentation I can not figure if it is possible. Do you have any configuration of resistors(R4,R5,R6) in order to modify Vuvp and Veoc?

I would like the failure rate for St Micro part numbers Viper26HDTR and Mastergan 1TR. Thank you very much. Ken Neubeck Reliability engineer, NAI

Hi, was wondering whether it would be possible to acquire the Failure Rate (MTTF or MTBF or FIT) for the following product: BAT46 Series (BAT46JFILM). Thank you.

STEPPER MOTORS: hey is there any algorithm for stepper motor controll?

Hi, I would like to know if it is possible to obtain failure rates (MTTF, MTBF, or FIT) for the following products: LD1117DT33CTR, L7812ABD2T-TR, L7805ABD2T-TR, L6565DTR. Thank you.

How do I bypass the latch function of the PM6644 converter?

I would also like to know if there is a way to at least cycle the enable pin with a hardware circuit if the part does latch.

We have received ST1D14PH units, some reels are identified as: ST1D14PHR$B7, marked as MSL=3 and other reels identified as: ST1D14PHR$B5, marked as MSL= 1. Can you tell us what this difference is due to?

Hi, I need recommendation for On / Off push button controller. After configurable hold time the controller will enable the system power on. After different configurable hold time the the controller will enable the system power off.

I need simple implementation.Hold time for On and hold time for Off can be configured be resistors / capacitors assembly.Could you please suggest for relevant IC?Thanks!Erez
