LM393WDT Frequently Asked Questions (FAQ)
-
The LM393WDT can operate from -40°C to 125°C, but the watchdog timer functionality is only guaranteed to work correctly up to 105°C.
-
To disable the watchdog timer during power-up and reset, connect the WDI pin to VCC through a resistor (typically 1 kΩ). This will prevent the watchdog timer from triggering during power-up and reset.
-
The minimum timeout period for the watchdog timer is 3.4 ms, and the maximum timeout period is 2.7 seconds. The timeout period can be adjusted by selecting the appropriate resistor and capacitor values for the oscillator circuit.
-
Yes, the LM393WDT can be used as a voltage supervisor. The device has a built-in voltage detector that can be used to monitor the supply voltage and generate a reset signal if the voltage falls below a certain threshold.
-
The oscillator frequency for the watchdog timer can be calculated using the following formula: f = 1 / (1.38 * R * C), where R is the resistance value in kΩ and C is the capacitance value in nF.
