6.1 Absolute Maximum Ratings

Over operating free-air temperature range, unless otherwise noted (1)
MIN MAX UNIT
Voltage VDD, SENSE, RESET (TPS3899DL) –0.3 6.5 V
CTR, CTS, RESET (TPS3899PL), RESET (TPS3899PH) –0.3 VDD+0.3 (3) V
Current RESET pin and RESET pin ±20 mA
Temperature (2) Operating ambient temperature, TA –40 125 °C
Temperature (2) Storage, Tstg –65 150
(1) Stresses beyond those listed under Absolute Maximum Rating (AMR) 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 Condition. Exposure to absolute maximum rated conditions for long periods may affect device reliability.
(2) As a result of the low dissipated power in this device, it is assumed that TJ = TA.
(3) The absolute maximum rating is (VDD + 0.3) V or 6.5 V, whichever is smaller.
