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:
4. _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.
5. For _JC, the “case temp” location is the center of the exposed metal pad on the package underside.
6. _JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
7. For J_C, the “case temp” location is taken at the package top center.
Electrical Specifications T_A = +25°C, V_CC = 3.3, VINP = V_BUS = 12V, V_SENSE = VINP-VINM = 32mV, unless otherwise specified. All
voltages with respect to GND pin.
