Pin Configuration

The MAX16047ETN+CC3 has a 16-pin Thin Quad Flat No-Lead (TQFN) package. The pin configuration is as follows:

1. VDD: Power supply input
2. GND: Ground reference
3. RESET#: Active-low reset output
4. MR#: Manual reset input
5. WDI: Watchdog input
6. NC: No connection
7. NC: No connection
8. NC: No connection
9. NC: No connection
10. NC: No connection
11. NC: No connection
12. NC: No connection
13. NC: No connection
14. NC: No connection
15. NC: No connection
16. NC: No connection

Functional Features

• Voltage monitoring: Monitors the supply voltage and asserts the reset signal when it falls below the specified threshold.
• Watchdog timer: Detects system malfunctions by periodically checking for a pulse on the watchdog input pin. If no pulse is detected within the timeout period, a reset signal is generated.
• Manual reset: Allows for an external reset signal to be applied to the MR# pin, overriding the voltage monitoring and watchdog timer functions.

Advantages and Disadvantages

Advantages: - Low-power operation - High accuracy in voltage monitoring - Flexible threshold voltage options - Integrated watchdog timer

Disadvantages: - Limited number of available pins for general-purpose use - Not suitable for applications requiring higher voltage thresholds

Working Principles

The MAX16047ETN+CC3 operates by continuously monitoring the supply voltage using an internal voltage reference and comparator. When the voltage falls below the programmed threshold, the reset output is asserted, indicating a power failure or low voltage condition. The watchdog timer ensures system integrity by periodically checking for a pulse on the WDI pin. If no pulse is received within the specified timeout period, the reset output is activated.

Application Field Plans

The MAX16047ETN+CC3 is commonly used in various electronic systems where reliable voltage monitoring and system reset functionality are required. Some application fields include:

1. Microcontrollers and microprocessors
2. Industrial control systems
3. Power management circuits
4. Battery-powered devices
5. Embedded systems
