Detailed Pin Configuration

LTC2903IS6-E1#TRPBF has six pins arranged as follows:

```

---

| | --| VCC |-- --| GND |-- --| TH |-- --| OUT |-- --| /RESET|-- |_______| ```

1. VCC: Power supply input pin.
2. GND: Ground reference pin.
3. TH: Threshold voltage setting pin.
4. OUT: Output pin indicating the status of the monitored voltage.
5. /RESET: Reset pin for clearing the output latch.

Functional Features

• Monitors power supply voltage and compares it with the threshold voltage.
• Provides an output signal indicating whether the voltage is above or below the threshold.
• Offers a reset function to clear the output latch.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems.
• High threshold accuracy ensures reliable monitoring.
• Low quiescent current minimizes power consumption.

Disadvantages

• Limited number of pins may restrict additional functionalities.
• SOT-23 package may require careful handling during assembly.

Working Principles

LTC2903IS6-E1#TRPBF operates by comparing the monitored power supply voltage with the threshold voltage set using the TH pin. If the voltage exceeds the threshold, the OUT pin is driven low, indicating an "under-voltage" condition. Conversely, if the voltage falls below the threshold, the OUT pin is driven high, indicating an "over-voltage" condition. The /RESET pin can be used to clear the latch and return the output to its default state.
