The TPS3823-33DBVT is a highly reliable, low-power supervisory circuit designed by Texas Instruments to monitor power supplies in digital systems. It provides a crucial function in ensuring system integrity by asserting a reset signal whenever the VCC supply voltage drops below a predefined threshold, keeping it asserted until VCC has stabilized above the minimum VCC threshold for a predetermined time period. This feature helps to prevent erroneous operation during power-up, power-down, and brown-out conditions.

Key Features

• Supply Voltage Supervision Range: The device is designed to monitor a fixed supply voltage of 3.3V, which is common in digital systems, ensuring compatibility and easy integration.
• Programmable Delay Time: The TPS3823-33DBVT offers a programmable time delay, providing designers with flexibility to set the reset time according to system requirements.
• Manual Reset Input: An additional feature includes a manual reset input that allows for a system reset to be initiated by an external source, providing an extra layer of system control.
• Low Supply Current: With its low supply current draw, this supervisory circuit is an excellent choice for battery-powered and low-power applications.
• Reset Output Options: The device comes with both active-low and open-drain reset outputs, accommodating various logic levels and interfacing needs.
• Temperature Range: The TPS3823-33DBVT operates over a wide temperature range, making it suitable for industrial and automotive applications.
• Small Form Factor: Housed in a SOT-23-5 package, the device has a compact footprint that is ideal for space-constrained applications.
