Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the specified range of 4.75V to 5.25V.
   • Connect VCC to a stable power source.

2. Watchdog Timer:

   • The watchdog timer period (tWDT) can be adjusted by changing the resistance of the external resistor (RWD).
   • For typical operation with RWD = 20 kΩ, the timer period is approximately 1.6 seconds.

3. Manual Reset:

   • A manual reset can be initiated by pulling the MR pin low.
   • The reset delay (tMRD) is typically 400 ms.

4. Power-Good Output:

   • The PG output indicates whether the supply voltage is within the specified range.
   • The rising threshold (VPG) is typically 4.75V, and the falling threshold is typically 4.25V.

5. Reset Timeout:

   • The reset timeout (tRTO) is the duration for which the reset signal is held active after a power-on or reset event.
   • It is typically 400 ms.

6. Output Drive Capability:

   • The device can sink up to 20 mA and source up to 20 mA on its output pins.

7. Quiescent Current:

   • The quiescent current (IQ) is the current drawn by the device when all outputs are low.
   • It is typically 20 μA.

8. Temperature Range:

   • The operating temperature range (TOPR) is from -40°C to 85°C.
   • The storage temperature range (TSTG) is from -65°C to 150°C.

9. Handling and Storage:

   • Store the device in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage the device.

10. Application Notes:

    • Refer to the datasheet for detailed application notes and circuit diagrams.
    • Ensure proper decoupling capacitors are used to stabilize the power supply and reduce noise.
