Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 1. 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. 2. For JC, the “case temp” location is the center of the exposed metal pad on the package underside. Electrical Specifications VIN = 12V, VBOOST = VSUP = 15V, VON = 25V, VOFF = -8V, over-temperature from -40°C to +105°C, unless otherwise stated. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested.
