Overview of Texas Instruments TPS3128E12DBVR

The TPS3128E12DBVR is a compact, low-power supervisory circuit designed by Texas Instruments to monitor power supplies in digital systems. It provides essential functions such as power-on reset control, supply voltage supervision, and manual reset capability, ensuring reliable operation of microprocessors, microcontrollers, and other digital systems.

Key Features

• Supply Voltage Supervision: The TPS3128E12DBVR is designed to monitor a fixed supply voltage of 1.2V, providing a precision threshold to ensure proper system operation.
• Power-On Reset (POR) Generator: The device generates a reset signal when the supply voltage becomes higher than the threshold, ensuring the system starts in a known state.
• Manual Reset Input: An additional feature includes a manual reset input that allows for an external trigger of a reset event, offering increased system control.
• Low Supply Current: With its low supply current draw, the TPS3128E12DBVR is ideal for power-sensitive applications.
• Small Form Factor: Housed in a tiny SOT-23-6 package, it requires minimal board space, making it suitable for space-constrained applications.
