Instructions for Using the MAX813LCSA

1. Supply Voltage (VCC):

   • Ensure the supply voltage is within the range of 2.5V to 5.5V.
   • The device operates optimally at 4.95V.

2. Supply Current:

   • The active supply current is typically 60μA at 5V.
   • The watchdog supply current is typically 20μA at 5V.

3. Watchdog Timer:

   • The watchdog timeout period can be adjusted using an external resistor (RWD).
   • For RWD = 10kΩ, the typical timeout period is 2.0 seconds.

4. Manual Reset Input (RESET):

   • The manual reset input is active low and should be kept above 0.8V to avoid triggering a reset.

5. Manual Reset Timeout:

   • After a manual reset, the device will hold the reset state for approximately 150ms.

6. Power-Good Output (PG):

   • The power-good threshold is set to detect when the supply voltage rises above 4.65V.
   • The hysteresis ensures stable operation, with a typical value of 200mV.

7. Output Drive Capability:

   • The device can sink up to 20mA and source up to 10mA at 5V.

Additional Notes:

• Ensure all connections are secure and free from short circuits.
• Use appropriate decoupling capacitors near the VCC pin to stabilize the power supply.
• Refer to the datasheet for detailed pin configurations and application notes.
