Power Interface Module
The IQ65033QMA10 iQor™ Power Interface Module
integrates all features required by the AdvancedTCA
Base Specification into a Quarter-Brick footprint. The
iQor offers industry leading external hold-up capacitor
volumetric density for a compact overall solution. At
a 90V hold‑up capacitor voltage (trimmable 50-95 V),
only 564 µF is required to achieve 8.70ms hold‑up time
at 200Win. The -48 V output voltage is conditioned for
smooth operation through severe input transient events.
The iQor is designed thermally and electrically to drive
high power wide-range-input DC/DC converters such as
the 300 W SynQor PQ60120QEA25. RoHS Compliant see
last page.

If the 5.0 V load current exceeds 100 mA, up to 200 mV of additional voltage drop is possible on the 5.0 V output.
Maximum DC load at startup is 50 mA. Full load can be applied 700 ms after enable or 400 ms after the management power is up and running.
Hold-up operation with Vin < 43 V not required by ATCA specification.
48 V output does not recover after hold-up event unless input is above Arm Hold-up threshold.
Does not inhibit 48 V output and is non-latching.

FEATURE DESCRIPTIONS
Input ORing MOSFETs: ORing of dual -48V feeds is provided
by four MOSFETs, which are individually controlled so as to operate as an ideal diode (see Figure A). If there is an input feed short
of any kind, a control circuit will detect reverse current and turn
off the MOSFET in 250ns (typ.), to avoid disturbing the other feed
voltage. At zero current, the MOSFET is guaranteed to be off. In
the case of a fuse failure, this triggers the ALARM output, due to an
apparent input feed loss. Current hysteresis prevents limit cycling
around the transition point between body diode and MOSFET
conduction.
ALARM Output: The ALARM pin gives an external indication
of a fault condition. It is an isolated and buffered open-collector
output, which is normally pulled low. In the presence of an input
feed loss (which can be caused by a fuse failure), the ALARM output will be tri-stated.

Phone 1-888-567-9596
External Input Fuse Failure Detection: At zero current, the
input ORing MOSFETs are guaranteed to be off. In the case of a
fuse failure, an on-board bleed resistor pulls the input feed voltage
down. This triggers the ALARM output due to an apparent input
feed loss. There are two main down-sides to this approach. First,
there is no way to distinguish between a feed loss and a fuse failure. Second, an enable fuse loss is not detected, since the enables
are diode OR’d.
The full featured version of the iQor offers additional data reporting that makes full fuse detection possible. Among other data,
each feed voltage and each enable voltage is reported through
the I2C port. These voltages can be compared with the voltages
reported by the shelf manager to determine whether any board
fuse is blown.

Technical Specification
Input Enable: The ENABLE_A/B signals connect to VRTN_A/B
on the backplane via the shortest pins in the zone 1 connector.
They are the last pins to mate during board insertion, and the
first to disconnect during board extraction. The ENABLE_A and
ENABLE_B signals are diode-ORed together which lets either signal enable the module. Whenever both ENABLE pins are open,
the hot-swap switch is opened. This prevents -48V output power
from being drawn though the EARLY pre-charge resistors.
The ENABLE signals also control the management power. On
board insertion, the management power remains off until at least
one of ENABLE_A/B is connected. On board extraction, the
management power is disabled at the end of the 100ms hold-up
period, and remains off until ENABLE_A/B is reconnected. This
prevents the IPMI controller from reading an invalid hardware
address when a board is partially inserted. Management power
flows through the EARLY pre-charge resistors for a maximum of
100ms, which provides a margin similar to the pre-charge event
in terms of resistor safe-operating-area.
EARLY Precharge Resistors: The EARLY_A/B signals connect
to the longest pins in the zone 1 power connector, and therefore
first to mate during board insertion. External resistors connected
between these signals and VRTN_A/B allow the relatively small
EMI filter capacitance to be pre-charged before the main power
pins make contact. A 100W surge rated 2010 case size resistor
is recommended (KOA SG73 series or equivalent).
Hot Swap - Thermal Shutdown: To protect the unit from
damage in an abnormal thermal environment, the hot-swap switch
will be disabled when the thermal sensor temperature rises above
the turn-off threshold. The switch will be automatically enabled
again when the temperature goes below the turn-on threshold.
The management power remains on during an over-temperature
condition.
The full featured version of the iQor reports the actual temperature
through the I2C port.
Hot Swap - Over-Current Protection: If the -48V output
current rises above the current limit threshold, the hot-swap switch
will be disabled, and will immediately enter another soft-start
sequence. If an output short is detected, the hot-swap switch
will be disabled and will enter a hiccup mode of operation with
automatic restart.
The full featured version of the iQor reports actual output current
through the I2C port.

5.0 V/ 3.3 V

Quarter-brick
The iQor unit conditions the -48V output, providing for seamless ride-through of input voltage transients. If the positive dV/
dt of the input voltage is too high, the hot-swap switch will be
disabled and will immediately enter another soft-start sequence.
This limits the dV/dt seen on the -48V output, which prevents the
12V payload power converter from having such a large glitch
on its output that it shuts down. The -48V output hold-up function
remains active throughout, in case the hot-swap switch is forced
off for too long.
Passive Transient Suppression: Each input feed has a dedicated internal bidirectional TVS zener diode, rated for a minimum
clamp voltage of 77.8V at 1mA. A TVS diode short due to electrical overstress will not disable the iQor module: a fuse will open,
and the module can continue to run from the other feed.
External Hold-up Capacitor Charge: A current controlled
DC-DC converter charges the external hold-up capacitor to a voltage of 50V-95V, set by an external resistor. The charge voltage
can range either above or below the input feed voltage. Constant
current charging takes place whenever the hot-swap switch is
enabled.
Hold-up Capacitor Connect: When the hot-swap switch is
enabled, 2 seconds are allocated to charge the hold-up capacitor. After this time, a comparator is armed, which connects the
hold-up capacitor to the -48V output should the output ever drop
below the given connect threshold. A current limit circuit protects
against damage during a short circuit condition. A dV/dt limit circuit regulates the hold-up connect switch turn-on speed. When the
comparator is tripped, the hold-up connect switch remains closed
for 100ms, is off for 2 seconds to allow the hold-up capacitor to
recharge, and then is automatically rearmed (if the output voltage
is above the given arm threshold).
Hold-up Capacitor Discharge: Whenever the hot-swap
switch is disabled, an internal resistor bank is connected across
the hold-up capacitor. This is intended to reduce the voltage on
the hold-up capacitor below 60V within 1 second.
Management Power: An isolated management power
converter delivers both 3.3V and a low power 5.0V relative
to LOGIC_GND. Over-current protection operates in constant
current with a hiccup mode if the output voltage drops too far.
Output over-voltage circuitry is included with a redundant reference and optocoupler.
Hot Swap - Transient Suppression: Input transient events
can occur if there is a short on an adjacent board or backplane.
The short builds up a large current in the wiring inductance,
and when a fuse blows, the voltage behind the fuse spikes very
quickly. This can cause a loss of redundancy since many other
boards could be exposed to this spike.

Hot Swap – Shutdown Timing: In the event of a sudden loss
of input voltage (see Figure B), a hold-up event will be triggered.
When the output voltage (plus a diode drop for the hot-swap body
diode) decays to the management power under-voltage turn-off
threshold, the main -48V output and the 3.3V/5.0V outputs will
shut down simultaneously.

operation for input voltages below the Hold-up Arm Threshold.
Management power will continue to run until the input voltage

Typically a strong function of VH (see Figure D).
The ATCA specification requirement is 8.70ms (see Figure E).
Where:
VH = hold-up capacitor charge voltage.
VU = minimum operating voltage on the 48V output; the greater
of the under-voltage lockout threshold of the payload power
converter, and the under-voltage lockout threshold of the
management power converter.
tH = time from when the highest input feed voltage drops below
VF, to the time when the highest input feed voltage rises
above VU.
VF = voltage at which the hold-up capacitor is engaged.
PH = power drawn from the hold-up capacitor, the sum of the input
power of the payload power converter, and the input power
of the 3.3V mgmt power converter (see Figure 9):

Figure E: The PICMG 3.0 R2.0 AdvancedTCA Base Specification
requires continuous operation through a zero-volt transient, lasting 5ms
(Section 4.1.2.2). However, this is not a square wave: the voltage starts
at a minimum amplitude of -43V, falls at 50V/ms, remains at 0V for
5ms, and then rises at 12.5V/ms. At the worst case values of the hold-up
connect threshold and the management power under-voltage lockout
threshold, the required hold-up time is 8.70ms.
Operating electrolytic capacitors near their voltage rating does
not significantly affect their reliability, as it does with tantalum
or ceramic type capacitors. The operating life of electrolytic
capacitors is primarily determined by the capacitor internal
temperature. The capacitor lifetime roughly doubles for every
10ºC reduction in internal temperature. SynQor recommends
running 100V rated electrolytic capacitors at 90V, which
dramatically increases hold-up time for a given capacitor volume
(see Figure D). A built-in circuit automatically discharges the
hold‑up capacitor when the input voltage is removed.

I2C Protocol: Reading from any internal register of the iQor
monitor requires that an internal (pseudo) register, Data_Pointer,
be initialized prior to reading (see Figure H).
Data_Pointer is write-only. It is written from the second byte of
any I2C WRITE message (the first byte is the 7 bit I2C Address
and the R√W bit). Subsequent data bytes in a WRITE message
(3rd Byte and beyond) only increment Data_Pointer.
Any READ message will return the value of the internal register
referenced by Data_Pointer and increments Data_Pointer by
one. For instance, if the master acknowledges (AK), the next
internal register referenced by Data_Pointer will be returned
and Data_Pointer will be incremented by one. This process is
repeated until the master does not acknowledge (NACK) and
issues a STOP bit.
Data_Pointer is an 8bit value. It is initialized to 00h at reset, and
after reaching FFh, it will not overflow.
Writing to registers not defined in Table 1 has no effect. Reading
from these undefined registers will return 00h. In both cases
Data_Pointer is incremented.
Figure H: Typical I2C read transmission. Note: S = START, W =
WRITE, R = READ, AK = acknowledged, NACK = NOT acknowledged, P = STOP. Clear boxes originate in the I2C Master and
shaded boxes originate in the I2C Slave.
