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.

(1)

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).
