APPLICATIONS

OPTIMIZED RELIABILITY WITH THE THERMAL

PROTECTION CIRCUIT

POWER SUPPLY SEQUENCING

As indicated in the Absolute Maximum Ratings section, the

voltage at any input pin cannot exceed its supply voltage by

more than 0.5 V. Power-on and power-off sequencing may be

required to comply with the Absolute Maximum Ratings.

The AD8386 is designed for enhanced reliability through

features that provide protection against accidental shorts that

may occur during PCB assembly repair, such as solder bridging,

or during system assembly, such as a misaligned flat panel cable

in the connector.

Failure to comply with the Absolute Maximum Ratings may

result in functional failure or damage to the internal ESD

diodes. Damaged ESD diodes may cause temporary parametric

failures, which may result in image artifacts. Damaged ESD

diodes cannot provide full ESD protection, reducing reliability.

While internal current limiters provide short-term protection

against temporary shorts at the outputs, the thermal shutdown

provides protection against persistent shorts lasting for several

seconds. To optimize reliability, the following sequence of

operations is recommended.

The following power supply sequencing ensures that the

Absolute Maximum Ratings are not violated.

Initial Power-Up after PCB Assembly or Repair

Power-on sequence is:

Disable grounded output mode and enable thermal protection.

• Turn ON AVCC and analog reference voltages.

• Turn ON DVCC and digital signals.

Power-off sequence is:

Ensure that the GCTL and GSW pins are LOW and the TSW

pin is HIGH upon initial power-up and remains unchanged

throughout this procedure.

• Execute the initial power-up.

• Turn OFF AVCC and analog reference voltages.

• Turn OFF DVCC and digital signals.

GROUNDED OUTPUT MODE DURING POWER-OFF

• Identify any shorts at the outputs.

• Power-down, repair shorts, and repeat the initial power-up

sequence until proper system functionality is verified.

Certain applications require that the video outputs be held near

AGND during power-down. The following power-off sequence

ensures that the outputs are near ground during power-off and

the Absolute Maximum Ratings are not violated.

Power-Up during Normal Operation

Disable grounded output mode and disable the thermal

protection circuit using either of the following two methods:

• GCTL = HIGH, TSW = HIGH and serial code

0XXXXXXXXXXX sent immediately following a power-up,

places all outputs into normal operating mode and disables

the thermal protection circuit.

• Enable grounded output mode in one of two ways:

GTCL = LOW and GSW = LOW, or GCTL = HIGH

and code 1XXXXXXXXXXX sent via the serial interface.

• Turn OFF AVCC and analog reference voltages.

• Turn OFF DVCC and digital signals.

• TSW = LOW disables the thermal protection circuit.

GCTL = LOW and GSW = HIGH puts all outputs into

normal operating mode.

OPERATION IN HIGH AMBIENT TEMPERATURE

To extend the maximum operating junction temperature of the

AD8386 to 150°C, keep the thermal protection circuit disabled

(TSW = LOW) during normal operation.
