It is part of the TPS3809 series which is designed to monitor the supply voltage in a system and assert a reset signal when the voltage falls below a specified threshold. This particular model, the TPS3809I50, is set for a 5.0V threshold.
The TPS3809I50DBVR comes in a SOT-23-5 package, which has 5 pins. The pin functions are typically as follows:
1. GND (Ground): Connects to the ground of the circuit.
2. VDD (Supply Voltage): The pin where the input voltage to be monitored is applied.
3. RESET (Reset Output): An active-low output that goes low when VDD falls below the threshold voltage, and remains low for a specified delay after VDD rises above the threshold.
4. NC (No Connect): Not connected internally; used for mechanical stability.
5. MR (Manual Reset): Allows for an external reset input, which can manually trigger the reset function.
These functions enable the TPS3809I50DBVR to ensure that a microcontroller only operates when the power supply is stable, preventing malfunction due to low voltage.
