LM1949: Minimum input frequency

Scarlett Cao

Part Number: LM1949

Hi team,

My customer is using LM1949 as solenoid driver in a valve project. According to the datasheet, the minimum input frequency is 10Hz. They would like to know whether it is feasible to use it at 5Hz and what will be the risk?

Thanks,

Scarlett

Hi Scarlett,

No issues running at a lower frequency - Vin can be at DC if desired. The values in the datasheet are there as typical numbers as an example in switching examples. Again, a lower frequency is OK.
