INA301: OCP for 400V DC BUS

Part Number: INA301

Customer would like to implement a OCP function with high DC bus to realize quick fault response time once OC event.

Do we have INAxxx product or roadmap that can support such application? it looks the INAxxx device needs to sustain the voltage rating up to 600V at least. 

application: HV Motor Drive

Function: OC Protection

Watts: 100W to 20KW

DC Bus Voltage: 400V

  • Hello Brian,

    Thanks for reaching out on the forum.  We do not currently have a stand alone IC available or in the pipeline that would  be able to handle a DC bus voltage of 400V.  However, I will connect you with some systems engineers in our group as they are more familiar with the roadmap.  Besides connecting with them, you may consider looking at one of the isolated amplifiers found here.

  • Hello Brian,

    As I have connected you with some of our systems engineers and you are now being serviced through email, I am going to close this thread.  However, if you do need further support regarding this topic, whether it be a workaround for these measurement conditions with our devices or about a specific current monitor, feel free to reply below to reopen the thread or just start a new thread.
