THERMAL RESISTANCE, FOUR-LAYER BOARD:
For the latest package outline information and land patterns (footprints), go to
www.maximintegrated.com/packages.
Note that a “+”,
“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
For detailed information on package thermal considerations, refer to
www.maximintegrated.com/thermal-tutorial.
Note 1:
SETI is internally clamped. Forcing more than 5mA current into the bump can damage the device.
