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). Floating this pin enables the driver and the UVLO circuitry when V_DD
reaches the UVLO threshold. A resistor divider can set a different UVLO threshold
voltage as shown on page 1 (See “Application Information” section for more details).
