Pinout
The functions of the pins are as follows:
1. VOUT: Output voltage; provides a stable reference voltage (2.9V).
2. GND: Ground; the common reference point for the circuit.
3. VDD: Supply voltage; typically connected to the input supply voltage for operation.
4. RESET: Output signal that indicates the status of the power supply; goes low when VDD falls below a specific threshold.
5. SENSE: Monitors the voltage; used for adjusting the reset threshold.
The MAX6443 provides a reliable voltage reference along with supervisory functions to ensure system stability.
