Part Number: ISO5451 Dear Teams,
My customer is asking what is the resistor value on the internal RST pin? The reason they are asking is because they have a reset signal with maximum output current capability 50mA. They are wondering whether it can successfully…
Part Number: ISO5451-Q1
We received a query from customer asking for the following information about the 9.3.2 Active Output Pull-down in the datasheet. For me to not miss any information from our customer, I will be copying the complete query…
Part Number: ISO5451 hi team
My customer is using ISO5451 in their project and the PWM goes to STO from MCU and then goes to ISO5451. Due to voltage drop over the long distance, sometimes ISO5451 has no signal output. do you have any suggestions to solving…
Part Number: ISO5451 Hi Team
I have a question about a recommended connection for DESAT pin in ISO5451, where I should to connect a zener diode in parallel to the 220pF capacitor and I'd like to know how I could calculate the reverse voltage in Zener that…
Part Number: ISO5451 My application is single pulse for few mS, I think the desat function might not be able to use, could you please let me know the control signal timing for the inside MOSFET connected to DESAT pin?
Part Number: ISO5852S ISO5451 ISO5452 ISO5851 Other Parts Discussed in Thread: ISO5451 , ISO5452 , ISO5851
What are the differences between ISO5851, ISO5852S, ISO5451, and ISO5452?
For what applications do the different features matter?
To provide an update: - A new Controller Board and new Power Board was used. The Controller Board had new ISO5451 gate drivers. - I then replaced the ISO5451 with a new ISO5851 only on the problematic gate driver on one of the Controller Boards…
Part Number: ISO5451 Hi Team,
I have a need for a desat circuit when the collector of the IGBT is tied to a 3kV supply. The circuit is using 3x 1200V diodes in series, 1kOhm from the HV bus to DESAT pin. Also, the DESAT pin has a 12V TVS diode and a…
Part Number: ISO5451-Q1 Hi
What are the failure modes and failure rates of ISO5451-Q1 when the isolation caps are broken? Short or Open? If it is short, how to guarantee the safety of the system? Thanks.
