Overview of TPS3820-33DBVRG4

The TPS3820-33DBVRG4 is a highly reliable, low-power voltage supervisor device designed and manufactured by Texas Instruments (TI). This component is specifically engineered to provide circuit initialization and timing supervision, primarily for DSPs and processor-based systems.

Key Features

• Voltage Monitoring: This device offers precise monitoring of a 3.3V supply voltage, ensuring that the system operates within the acceptable voltage range.
• Power-On Reset Generator: The TPS3820-33DBVRG4 has an integrated power-on reset generator that provides a clean start for microprocessors/microcontrollers by asserting a reset signal upon power-up until the supply voltage reaches a stable level.
• Manual Reset Input: An additional feature of this device is its manual reset input, which allows for an external trigger to reset the system, providing an extra layer of control.
• Low Supply Current: With a low supply current of typically 15 µA, this supervisor IC is optimal for power-sensitive applications.
• Long Reset Time Delay: It includes a built-in delay before the output reset signal is deasserted, ensuring the system has ample time to stabilize.
• Temperature Range: The device operates over a wide temperature range, making it suitable for various industrial and commercial applications.
• Small Form Factor: The TPS3820-33DBVRG4 comes in a small 5-pin SOT-23 package, making it ideal for space-constrained applications.
