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:
1. θ_JA 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, and Tech Brief TB389.
2. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Test Conditions: ISL4238E V_CC = 3.15V to 5.5V, C₁ to C₄ = 0.1µF; V_CC = 3V, C₁ to C₄ = 0.22µF;
ISL424xE V_CC = 3V to 5.5V, C₁ to C₄ = 0.1µF; Unless Otherwise Specified. Typicals are at T_A = +25°C
