LM63: Can LM63 be used as a direct FAN drive?

Christina Lim

Part Number: LM63

Hi,

My customer is planning to use LM63 for a direct FAN drive application. If there is no feedback, TACH to LM63, would LM63 work?

I saw that the TACH/ALERT is programmable for ALERT use only, thus the question is whether a TACH is necessary?

Thanks,

Christina

Dear Christina -

Pin 6 is defaulted to ALERT, it can be programmed for and used for TACH function. See register 0x4A, 4B descriptions on page 21 and the setting of bit 2 in Register 0x03 (page 24), Registers 0x47 - 0x49 (page 25)

Hi Christina,

If no feedback is necessary then you can use the device in ALERT mode and use as fan driver.

Thanks,
