Overview of Texas Instruments TPS3306-33DR

The TPS3306-33DR is a sophisticated dual-voltage supervisor designed by Texas Instruments to provide circuit designers with an effective solution for monitoring two non-programmable voltage nodes. This integrated circuit (IC) is particularly well-suited for applications that require a high degree of reliability and accuracy in voltage supervision, making it a popular choice for use in systems such as microcontrollers, microprocessors, and FPGAs.

Key Features

• Dual Voltage Supervision: The TPS3306-33DR is capable of monitoring two voltages simultaneously, ensuring that both supply rails are within acceptable thresholds before enabling the system to operate.
• Fixed-Sense Threshold Voltages: This device comes with preset threshold voltages of 3.3V for the primary channel and a 1.5% accuracy rate, which simplifies the design process by eliminating the need for external resistors.
• Manual Reset Input: A manual reset input allows users to forcibly initiate a system reset, providing an additional layer of control over the system's operation.
• Low Supply Current: With its low supply current feature, the TPS3306-33DR is optimized for power-sensitive applications, ensuring minimal impact on the overall power consumption of the system.
• Built-in Delay: The device includes a built-in delay function that prevents false triggering due to transient voltage fluctuations, thereby enhancing system stability.
• Wide Operating Temperature Range: It operates effectively across a broad temperature range, making it suitable for various industrial and commercial environments.

Applications

The TPS3306-33DR is versatile and can be employed in multiple applications where precise voltage monitoring is crucial. It is commonly found in:
