Tool/software:

Hi team,

My customer have question for LDC5072-Q1. The purpuse to use this sensor is angular detection not using Hall IC.

Could you please teach me below things please?

#1. Please teach me estimated power comsumption when 5V/20,000rpm.

#2. How long does it takes OUTxx=HiZ from Normal operation once faults detects?

#3. They understand L1~L4 are optional. Could you tell me recommended value for L1~L4 if they choose the option.

Regards,

Youhei MIYAOKA

Hello Youhei,

1. Current consumption is specified at max 22mA.

2. I don't see this in the datasheet. I will need to look into this. I expect I can have an answer on Tuesday next week.

3. I would actually recommend using ferrites instead of inductors for filtering noise. The value will depend on the system and what frequencies need to be targeted.

Youhei,

For the second item, this is listed in the safety manual for the device. This requires an NDA and can be requested at the link below.
