Input (Input): Logic high produces a high output voltage for the MIC44F18 and a low output

voltage for the MIC44F19/20. Logic low produces a low output voltage for the MIC44F18 and

a high output voltage for the MIC44F19/20.

EN / Under-Voltage Lockout (Input): Pulling this pin below low disables the driver. When

disabled, the output is in the off state (low for the MIC44F18/20 and high for the MIC44F19).
