LM158WDT Frequently Asked Questions (FAQs)

  • The LM158WDT can operate from -40°C to 125°C, but the watchdog timer functionality is only guaranteed to work correctly between -20°C to 85°C.
  • The timeout period can be calculated using the formula: T = (R1 x R2 x C) / 1.4, where R1 and R2 are the resistors connected to the WDI pin, and C is the capacitor connected to the WDI pin.
  • The minimum value of the external capacitor (C) is 10nF, and the maximum value is 100nF. Values outside this range may not provide accurate watchdog timer functionality.
  • No, the LM158WDT is not designed to be used as a voltage regulator. It is a watchdog timer IC that provides a reset signal to the microcontroller in case of a fault or timeout.
  • The watchdog timer can be reset by applying a high signal to the WDI pin for a minimum of 1.4ms. This can be done by the microcontroller or an external circuit.
