Resolved! Current sense on high side driver VNQ9025AJ
Hey,I'm planning to use this high-side driver in a project distribution module, but I'm having trouble fully understanding how the current sensing works.I've looked at the schematic, and I see a combination of two resistors, Rprot and Rsense. Is this...
Need DPAK MOSFET with high avalanche rating
We've been using the On Semi FDD8453LZ MOSFET (40V, 6.7 ohm, DPAK) in our motor control designs for many years, but this part is now EOL. We're looking for a suitable DPAK replacement. One critical parameter is the single pulse avalanche energy, wh...
SPV1050 BATT_CHG output
Dears,There is SPV1050 in my circuit. Works without MPPT, boost mode. The problem concerns BATT_CHG state. Documentation says BATT_CHG output reflects DC/DC converter state, i. e. it is active (low) when DC/DC converter works. Simply saying:1. When i...
L9916 Device Program Mode
Trying to switch L9916 to device program mode.Followed every instruction in Application Note, but failed I2C communication with the device (L9916 does not generate acknowledge - so it seems, that the initial sequence failed?).Could someone give me a ...
VIPER319XD thermal and loss characteristics
I have reviewed the VIPER319XD datasheet and the Power Supply Design Tool, and I have a few questions about this IC:The datasheet only provides RthJA (80°C/W) and does not specify the RthJB value. In another datasheet for the same package, I found Rt...
SPV1050 input capacitance
Hi,currently, I'm designing a wireless sensor node with the SPV1050 energy harvester. However, as I read the datasheet, I got kind of confused with the input capacitance for the source. In the datasheet on page 21 there is mentioned that the selectio...
VIPER06 degradation in continuous self-biased mode
Good day to everyone! Could anyone consult us about the issue with using VIPER06 in flyback converter just in self-biased mode for all the operating time, as it shown in Figure 19 of datasheet DocID022794 Rev 2 and described in Chapter 8 of datasheet...
L9961 BMS IC Configuration and Debugging Issues
My name is Jeongsoo Lee. We are using the L9961 (BMS IC) and have configured the circuit using the L99615C development board to establish a basic framework. However, our battery solution requires a 3-series configuration. The datasheet and developmen...
How to calculate the current limit of STEF01?
Hi Sir, Could you share the equation of current limit?I cannot find the related equation in the datasheet.Thank you.
