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
