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.
NOTES:
5. The ISL78420 is capable of derated operation at supply voltages exceeding 14V. Figure 17 shows the high-side voltage derating curve for this mode
of operation.
6. All voltages referenced to V_SS unless otherwise specified.
7. 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.
8. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications V_DD = V_HB = 12V, V_SS = V_HS = 0V, R_DT = 0_K, PWM = 0V, No Load on LO or HO, Unless Otherwise Specified.
Boldface limits apply over the operating temperature range, -40°C to +125°C.
