Human Body Model (Tested per JS-001-2014) 2 kV Charged Device Model (Tested per JS-002-2014) 1 kV Latch-Up (Tested per JESD78E; Class 2, Level A) 100 mA
CAUTION:
Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions can adversely impact product reliability and result in failures not covered by warranty.
2.2 Thermal Information Thermal Resistance (Typical) θJA (°C/W) θJC (°C/W) θJB (°C/W)
8 Bump WLCSP Package (Notes 1, 2) 110 - 28 8 Ld 2x3 DFN Package (Notes 1, 3) 72 21 -
Notes:
1. θJA is measured in free air with the component mounted on a high-effective thermal conductivity test board with direct attach features. See TB379 2. For θJB, the board temperature is taken on the board near the edge of the package, on a copper trace at the center of one side. 3. For θJC, the case temperature location is the center of the exposed metal pad on the package underside. See TB379.
