Tutorial: How to use DS1232LPSN Voltage Supervisor

The DS1232LPSN voltage supervisor is an essential component for protecting electronic circuits from low or high voltage conditions. It is ideal for projects that require safe current management, such as Arduino prototypes or solar power systems.

What you need

• Arduino Uno
• JST Connectors
• Solderable Wires
• LiPo Battery

Steps

1. Check the DS1232LPSN’s minimum and maximum power supply voltage on the datasheet.
2. Connect the VCC pin to the positive terminal of the power supply.
3. Connect the GND pin to the common ground (GND) of the circuit.
4. Read the RESET and PGOOD pins from the datasheet to understand the current state of the IC.
5. If necessary, connect a capacitor between VCC and GND near the IC to filter out interference.
6. Connect the RESET pin to a digital input pin of the Arduino if you want to monitor the reset interruption.
7. Write a simple Arduino sketch that reads the state of the RESET and PGOOD pins.
8. Test the configuration with different power supply voltages.

Example code

// Verifica lo stato del supervisore DS1232LPSN
int resetPin = 2;
int pgoodPin = 3;
void setup() {
pinMode(resetPin, INPUT);
pinMode(pgoodPin, INPUT);
Serial.begin(9600);
}
void loop() {
digitalWrite(LED_BUILTIN, digitalRead(resetPin));
Serial.print("RESET:"); Serial.println(digitalRead(resetPin));
Serial.print("PGOOD:"); Serial.println(digitalRead(pgoodPin));
deLAY(1000);}

Mini project

Create a protection system for an Arduino prototype that automatically shuts off when the battery voltage drops below the set minimum value.

Common mistakes

• Connect VCC and GND to the circuit incorrectly.
• Ignore the bypass capacitors near the IC.
• Do not check the status of the RESET and PGOOD pins in the Arduino code.

Recommended accessories

• JST Connection
• 10uF Capacitor
• 3.7V LiPo Battery
