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. For ΘJC, the “case temp” location is taken at the package top center. IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA. Electrical Specifications VDD = 5V, VBOOST = 11V, ILOAD = 200mA, VON = 15V, VOFF = -5V, VLOGIC = 2.5V, limits over -40°C to +105°C temperature range, unless otherwise specified. Boldface limits apply over the operating temperature range, -40°C to +105°C.
