Control and Protection
Serial bus interface: PMBus®
Current share: Active
Remote sense: 2-wire (+ and -)
Remote inhibit: Pull inhibit low = main & fan output OFF (5 V standby is ON); Pull inhibit high (or floating) = all outputs ON
AC OK: Active high when normal AC input is present (with internal 10 kOhm pull up to 3.3 V)
DC OK: Active high when main O/P is within regulation (with internal 10 kOhm pull up to 3.3 V)
Smart fan control: Monitor, control and override
Overvoltage protection: Latch (AC recyle or inhibit toggle required for PSU restart)
Overload protection: Auto-recovery (constant current mode down to 50% Vout)
Overtemperature protection: Auto-recovery with hysteresis
