STEVAL-ISD01KCB

I've been looking at the STEVAL-ISD01KCB, and I saw in an image that it has some capacitors between pins 8 (-DC) and 9 (+DC). What is the value of that capacitor? Is it necessary to include it? I ask because I've noticed that this capacitor slightly ...

Is it possible to parallel multiple STEF01 e-fuses?

I have a design running on 24V SLA batteries using STEF01 fuses for protection of the lower powered rails and an LT4356 using external MOSFETs for a 25Amp rail. That 25A rail is giving me headaches. Staying within the SOA of the MOSFETs is not that e...

EVALSTGAP2HDM

Hi, We have been testing our H-bridge on 2 EVALSTGAP2HDM with IPP026N10NF2S MOSFETs. The gate resistances are as per the EVAL board. We are seeing huge ringing on the gate signals for the low side FETs on both boards with no load connected. The high ...
