DESCRIPTION (CONT.)
The TPS2480 and TPS2481 monitors shunts on buses that can vary from 9 V to 26 V and with a few external
components it is possible to monitor buses as high as 80 V.
The monitoring circuitry uses a single 3-V to 5.5-V supply, drawing a maximum of 1 mA of supply current.

Tested per JEDEC JESD51, natural convection. The definitions of high-k and low-k are per JESD 51-7and JESD 51-3.
(2)
Low-k (2 signal - no plane, 3 in. by 3 in. board, 0.062 in. thick, 1 oz. copper) test board with the pad soldered, and an additional 0.12
in.2 of top-side copper added to the pad.
(3)
High-k is a (2 signal – 2 plane) test board with the pad soldered.
(4)
The best case thermal resistance is obtained using the recommendations per SLMA002A (2 signal - 2 plane with the pad connected to
the plane).

Hotswap circuits may experience voltage surges during events such as hotplug and output shorts. The maximum Recommended
Operating Voltage is derated below the Absolute Maximum to allow for tolerance of protection devices (clamps). If the application does
not have input surges, the TPS2480 may be used up to its Absolute Maximum Rating with no degradation of performance or reliability.
