Conditions/Description
Reports information and monitors alarm functions
Contact closure to GND
TTL compatible signal, open collector. Power supply enabled at Low or TTL "0"
(e.g. by connecting of pin 22 to 0V or GND), and
inhibited to latching mode** at High or TTL "1", or leave it open.
Supervisory AC input voltage;
Pre-warning time >6 ms
Supervisory under- and overvoltage pre-ORing diode of V1
Indicates if unit is operating normally or in overtemperature,
Pre-warning time >10 ms
Indicates if fan is operating or has failed
Droop load characteristic for V1 and V2
LEDs: DC OK (green), AC OK (green)
* Signal provided by I 2 C interface or by open collector (OC)
** (1) Standard FNP300 models (without "H" at the end of part number) have latching inhibit function, i.e., once PSU is
inhibited, it needs input power re-cycle to allow using enable state again.
(2) FNP300 variants marked with "H" character do have non-latching inhibit function so there's no need to
re-cycle input power when enabling unit after inhibit state.
Features
All specifications apply over specified input voltage, output load, and temperature range, unless otherwise noted.
Fan speed level and temperature information available on I C digital bus
Parameter
Fan speed control
μC supply voltage in-/output

If unit is operating: 5 to 7V is provided at pin 10.
If unit is NOT operating, pin 10 is input from a parallel connected unit for μC supply.
