(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) IC is designed to be operational up to TJ = 175°C. Internal overtemperature shutdown will be disabled by default on the DRV8305xEPHPQ1.
(3) Because lifetime degrades exponentially at higher temperatures, operation between TJ = 150°C to 175°C must be limited to transient and infrequent events. For transient events between TJ = 150°C to 175°C for a total of 10 hours over lifetime, no degradation in lifetime is expected. Contact TI for lifetime impact if the use case requires TJ = 150°C to 175°C greater than 10 hours.
