Part Number:DRV10983
Dear ,
my customer use DRV10983 to design a fan BLDC driver,motor parameter is 24v/30w。
now the fan motor can run normally,but the input power is different,customer suspect it is the consistency issues。
the specific test is as below:
when customer use the same motor and set the same rotate speed on the same test board ,supply 24v input voltage,test 6pcs DRV10983,four of them the input current is1.2A,the others is 0.8A; take a new drv10983 to replace of the 0.8A chip,the new drv10983's input current is also 1.2A.
So customer suspect the chip's consistency is bad.
Can you give me a reasonable explain for customer? or how should i resove the issues.
the schematic as below.
Many thanks.
Best regards
Cickey Xu
