Pinout
The TPS3828-33QDBVRQ1 is a voltage supervisor IC manufactured by Texas Instruments. It comes in a 5-pin SOT-23 package. Here are the pin functions:
1. VDD (Pin 1): This is the supply voltage input pin where the monitored voltage is applied. It powers the device.
2. GND (Pin 2): This is the ground pin, serving as the reference point for the voltage levels within the device.
3. MR (Pin 3): This is the manual reset input pin. When taken low, it triggers a reset condition regardless of the VDD level.
4. RESET (Pin 4): This is the reset output pin, which goes low when the monitored voltage (VDD) drops below a specified threshold or when MR is activated.
5. WDI (Pin 5): This is the watchdog input pin. It requires a periodic signal to prevent the device from initiating a reset sequence, ensuring that the system is functioning correctly.
The TPS3828-33QDBVRQ1 is designed to monitor supply voltages and provide a reset signal to a microcontroller or processor during power-up, power-down, and brownout conditions.
