EVLPOWERSTEP01 Board Bill of Material & Technical Queries

[shrikant_swami]

Queries:

1. Could you please provide us manufacturer part numbers of all parts/components used on Evlpowerstep01 Board.

2. Provide shunt resistor 0R1/2W tolerance value.

3. Provide all decoupling capacitor type?

4. Value of Capacitor Cp used on evaluation board is 47nF/100V. Is there any formula to calculate this capacitor value or can we use 10nF/100V as mentioned in datasheet.

5. Do we need a specific 3.3nF/6.3V value capacitor on ADCIN pin. Can we select another generalised value like 10nF/6.3V.

Hello @shrikant_swami​ and welcome to the ST Community.

1. for the passive components and generic parts (e.g. LED or Zener diodes) we do not have a suggested manufacturer

2. the tolerance for the shunt resistors is 1 %

3. you can find all the value in the Bill Of Material

4. the device testing conditions can be different from the recommended operating conditions.

The suggested value for typical application is 47 nF / 100 V.

5. we use a small cap on ADC input because we do not expect the injected noise to be large. Feel free to use a bigger value.

Let me know if this info is useful to you, if yes please "Select as Best" label
