Thermal

Consideration

of

VTT

Active

Terminator

The VTT terminator is designed to handle large

transient output currents. If large currents are

required for very long duration, then care should

be taken to ensure the maximum junction

temperature is not exceeded. The 8-pin MSOP

with ExposedPAD has a thermal resistance of

In order to take full advantage of the thermal

capability of this package, the exposed pad

should be soldered directly onto the PCB ground

layer to allow good thermal contact. It is

recommended that the PCB should have 10 to 15

vias with 0.3mm drill size underneath the

exposed thermal pad connecting all the ground

layers

Supply Voltage Undervoltage Monitor

The IC continuously monitors VDRV. If VDRV is

set higher than its preset threshold and VTTEN is

high too, the IC will start up.

Thermal Shutdown

When the chip junction temperature exceeds

150

resumes normal operation only after the junction
