Pinout
The TLV1805DBVR is a high-voltage comparator from Texas Instruments. It comes in a SOT-23-5 package, which means it has 5 pins. Here is a brief description of each pin and its function:
1. Pin 1 (OUT): Output - This is the output pin of the comparator, which changes state based on the voltage comparison between the non-inverting and inverting inputs.
2. Pin 2 (V+ or VCC): Positive Supply Voltage - This pin powers the comparator. The TLV1805 can operate with a wide range of supply voltages.
3. Pin 3 (IN–): Inverting Input - This is one of the inputs to which the voltage is applied for comparison. The comparator outputs a low signal if this voltage is higher than the non-inverting input.
4. Pin 4 (IN+): Non-Inverting Input - This is the other input for voltage comparison. The comparator outputs a high signal if this voltage exceeds the inverting input.
5. Pin 5 (GND or V–): Ground - This pin is connected to ground or the lowest voltage in the supply range.
The TLV1805 is designed for low power consumption and can handle wide voltage ranges, making it suitable for various applications.
