The HI-3588PCI and HI-3588PCT use a 44-pin plastic

chip-scale package. This package has a metal heat sink

pad on its bottom surface that is electrically connected to

the die. For the HI-3588, the primary advantage of this

package is its small size; heat sinking provides little benefit

because HI-3588 dissipation is low. If connected, the heat

bottom sink pad should be connected to VDD.

Do not connect heat sink pad to GND.
