CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTE:
4.
θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5.
θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379 for details.
6. For
θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications
Test Conditions: VCC = 3.0V to 3.6V and 4.5V to 5.5V; VL = VCC (ISL32179E only); Typicals are at VCC = 3.3V
