If the power supply latches off due to a protection circuit tripping, an AC cycle OFF for 15 sec and a PSON# cycle HIGH for 1 sec are able to reset the power supply.

4.1 OVERVOLTAGE PROTECTION (OVP)

The power supply over voltage protection will be locally sensed. The power supply will shutdown and latch off after an over voltage condition occurs. This latch will be cleared by toggling the PSON# signal or by an AC power interruption. The values are measured at the output of the power supply’s connectors. The voltage should never exceed the maximum levels when measured at the power connectors of the power supply connector during any single point of fail. The voltage should never trip any lower than the minimum levels when measured at the power connector. 12 VSB will be auto-recovered after removing OVP limit.

4.2 OVER TEMPERATURE PROTECTION (OTP)

The power supply will be protected against over temperature conditions caused by loss of fan cooling or excessive ambient temperature. In an OTP condition the PSU will shutdown. When the power supply temperature drops to within specified limits, the power supply will restore power automatically, while the 12 VSB remains always on. The OTP circuit must have built in margin such that the power supply will not oscillate on and off due to temperature recovering condition. The OTP trip level shall have a minimum of 5°C of ambient temperature margin.

4.3 CURRENT LIMITATION (OCP)

The power supply has a current limit to prevent the outputs from exceeding the values shown in table above. If the current limits are exceeded the power supply shuts down and latches off. The latch will be cleared by toggling the PSON# signal or by an AC power interruption. The power supply will not be damaged from repeated power cycling in this condition. 12 VSB will be auto-recovered after removing OCP limit.

4.4 SHORT CIRCUIT PROTECTION (SCP)

The power supply shut s down and latch es off for shorting the main outputs. 12 VSB must be capable of being shorted indefinitely. The latch will be cleared by toggling the PSON# signal or by an AC power interruption. The power supply should not be damaged from repeated power cycling in this condition. 12 VSB will be auto-recovered after removing SCP limit.

4.5 OVER POWER PROTECTION (OPP)

The power supply supports over power protection (OPP) level low enough to protect the power supply running in this mode for repeated 1 msec durations at a 1% duty cycle. The power supply should be stable operating at any load point from rated power up to the OPP point. CRPS-185 Load Requirement for OPP Threshold = (Imax + 49 A) +/-50 W SMBAlert shall always assert ahead of the OPP threshold being exceeded

5.5 PWOK OUTPUT SIGNAL (PIN A25: PWOK)

PWOK is a power OK signal and will be pulled HIGH by the power supply to indicate that all the outputs are within the regulation limits of the power supply. When any output voltage falls below regulation limits or when AC power has been removed for a time sufficiently long so that power supply operation is no longer guaranteed, PWOK will be de-asserted to a LOW state. See Table: for a representation of the timing characteristics of PWOK. The start of the PWOK delay time shall inhibited as long as any power supply output is in current limit.

5.6 SMART ON CONTROL (PIN B22: ENABLE BY SYSTEM)

Before enabling Smart On function, make sure pin B22 (SMART ON) on output golden finger of each PSU is connected together. When the pin is HIGH in the Smart On mode, the slave power supply will enter the Smart Standby mode if system total loading under PSU’s pre-set load level. When the pin is LOW in the Smart On mode, the Smart Standby mode power supplies will work in normal redundancy mode. Smart On feature supports 1+1, 2+1, and 3+1 redundant configurations. It uses the PMBus manufacturer specific command area to define PMBus commands for the system to communicate with the power supplies for enabling, configuration, and monitoring. The Power Management Bus manufacturer specific command MFR_SPECIFIC_00 is used to configure the operating state of the power supply related to Smart On. We will call the command SMART_ON_CONFIG (D0h). Below is the definition of the values used with the Read-Write Byte SMBus protocol with PEC. The trigger levels above may have a +/-10% tolerance for actual application. The default state of power supply is in Standard Redundancy mode. Power supply need to be re-specified a state whenever initial power on or the operating module predicts failure. The SMART_ON_CONFIG command will reset to 00h (Standard Redundancy) when any fault happened. And when an active power supply asserts, all parallel power supplies in Smart Standby mode shall power on immediately.

5.6.1 SMART STANDBY POWER SUPPLY OPERATING STATE

A power supply is put into Smart Standby whenever PSON# is asserted, SMART_RED# is de-asserted, and SMART_ON_CONFIG value is set to 02h, 03h, or 04h. In the Smart Standby mode the power supply must. 1. Power ON when Smart_On bus is driven LOW. 2. Keep PWOK asserted. 3. No Power Management Bus fault conditions reported via STATUS commands, any fault happen will made PSU leave smart standby mode. 4. Keep all fans rolling 5. LED is green blinking under normal conditions, amber blinking if any warning conditions happen.

5.6.2 POWERING ON SMART STANDBY SUPPLIES TO MAINTAIN BEST EFFICIENCY

Power supplies in Smart Standby state shall monitor the shared voltage level of the load share signal to sense when it needs to power on. Depending upon which position (1, 2, or 3) the system defines that power supply to be in the Smart Standby configuration; will slightly change the load share threshold that the power supply shall power on at.

5.6.3 POWERING ON SMART STANDBY SUPPLIES DURING A FAULT OR OVER CURRENT CONDITION

Some warnings happen or 12V output shutdown due to any fault will cause SRED_OK# driven low.When an active power supply asserts its SRED_OK# signal, all parallel power supplies in Smart Standby mode shall power on immediately. The trigger condition: 1. 12V OC warning/ fault happens 2. 12V OVP fault 3. 12V Smart ON UVP (lower than 11.8V) 4. OTP fault 5. Fan speed fault 6. AC loss (Refer to section 3.1.3 table1, Power off voltage) 7. Send 00h to Power Management Bus D0h command 8. PSON# de-assertion happens

5.6.4 THE WAY TO ENABLE SMART ON FUNCTION

Here are the steps to put PSU into smart on mode. PSU which is assigned as smart on standby can operate in a power-off state and turn on main power if necessary.
