L6482 behaviour at high speeds

Hello,we want to use L6482 chip to substiture DRV8711 driver we have been using so far. However from our tests the driver does not behave equally as well. We took some oscilloscope screenshots showing that at high speeds the current provided to the m...

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...

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...
