Watchdog timing period calculation formula: tPWD [ms] = 0.466 * (REXT - 20) + 10 (REXT in kΩ) Table 3. Static Electrical Characteristics (continued) Characteristics noted under conditions 5.5V ≤ V SUP ≤ 18V, -40°C ≤ TA ≤ 125°C for the 33910 and -40°C ≤ TA ≤ 85°C for the 34910, unless otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal conditions, unless otherwise noted. Characteristic Symbol Min Typ Max Unit |
