What are the peak input power and current limit for SPV1050?
I'm using a 694W solar cell whose Voc is 6V, Vload = 5.03V at MPP (Maximum Power Point). Its Isc and ILoad are 160mA and 138 mA at MPP. Under this condition, is it safe to use SPV1050?
Cut-off voltage and source current of STNS01
I am working with the STNS01 for a new design and wanted to know the following. My use case is the LDO will power a microcontroller while the SYS will power a small vibration motor.1) Cut-off voltage for the LDO. ie At what battery voltage will the L...
MAR9114
Hi all,Has someone the MAR9114 datasheet? Where I can found it?The motor board has this IC and I'm not able to understand if it works rightly.Thanks in Advance.
Resolved! Can't find ST IC Soic-14 with : eZPY025, may be a PWM controler
Hay to everyone,My name is Tony, live in Melbourne, Au.I am fixing electronic boards for house appliance and often use ST products.This time I need to replace a IC from ST with writing : eZPY025, I think is a 100KHz PWM controler. Can't find anywhere...
What is the real minimum deadtime of MASTERGAN1?
Dear All,I am using MASTERGAN1 for DC-AC conversion. The Input is 400VDC. The output filter inuctor is 220uH. The norminal output current is 0.1A (Yes, very small).As suggested in the datasheet of MASTERGAN1, the minimum deadtime is 5ns. Firstly, 15n...
SPV1040 Not working
Hi,I have been working with SPV1040 and L6924D ICs. The SPV1040 doesn't seem to work in my design. I have designed the circuit and layout based on this app note. Without connect the battery for the first time. The SPV1040 generates 4.1V at output but...
How does STEVAL-ISV020V1 provide LDOs when the PV panel hasn't sunlight?
I am working with STEVAL-ISV020V1 and I have a PV pannel and a battery connected with 3.3 V close to the maximum capacity.When we don't have power supply on PV panel, shouldn't the battery voltage supply the system?for example, shouldn't it have 1.8V...
Resolved! How to use internal opamp in stspin32f0602
I have been using stspin32f0602 based on evspin32f0602s1. But the evaluation kit uses external opamp and comparator ic. I am looking for a way to use the internal opamp and comparator for amp measurements for easier hardware and inventory management....
VIPER26L compatibility with VIPER26K
Hi, we are using VIPER26LDTR in a non-isolated AC/DC converter with 220V AC line input and 16V DC output. Can we replace the chip with VIPER26K version without changing the circuit/PCB? The K version has a MOSFET capable to withstand 1050V but apart ...
