hv110 Supertex, Inc., hv110 Datasheet - Page 2

• Manufacturer Part Number: hv110
• Description: Power-over-ethernet Interface Pd Controller Meets Ieee802.3af Tm Standard
• Manufacturer: Supertex, Inc.

( 1 ): HV110 will work in both Positive and Negative voltage applications, the maximum differential voltage between the V
( 2 ): UVLO Threshold to be modified using external resistors, when a zener diode is connected to V
( 3 ): Shorted-circuit timer starts after POR timer. If V
( 4 ): Under-current timer starts when I
( 5 ): If the output current is in an overload or shorted load condition then the output immediately goes to current limit and starts the over-current timer. If I
( 6 ): Time for fast return to limit circuit to react.

* Absolute Maximum Ratings are those values beyond which damage to device
may occur. Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level my affect
