TPS3110E09DBVR - Texas Instruments

The TPS3110E09DBVR is a versatile supervisory circuit developed by Texas Instruments, designed to monitor power supplies in microprocessor and digital systems. It provides a significant level of protection by ensuring that the system voltage remains within acceptable thresholds, thereby enhancing system reliability.

This supervisory chip comes in a compact SOT-23-6 package, making it suitable for space-constrained applications. It is specifically engineered to monitor a single system supply voltage of 0.9V, which is common in low-voltage applications. The device features a precision voltage detector, which ensures that the system operates correctly by initiating a reset signal whenever the monitored voltage drops below a predefined threshold.

One of the standout features of the TPS3110E09DBVR is its programmable delay time. The device allows users to set the duration of the reset signal, which can be crucial for ensuring that the system has sufficient time to stabilize before normal operation resumes. This programmability is achieved through an external capacitor, providing flexibility to meet the requirements of various applications.

Key Features:

• Power-On Reset Generator with adjustable delay time via external capacitor
• Low supply current of 15 μA (typical), which is ideal for power-sensitive applications
• Manual reset input for triggering system resets as needed
• Watchdog timer for system fault detection
• Temperature range from -40°C to +85°C, suitable for industrial applications
• Supply voltage supervision range: 0.9V

The TPS3110E09DBVR also incorporates a manual reset input that allows for a system reset to be triggered manually, providing an additional layer of user control. Furthermore, the built-in watchdog timer serves as a system fault detection mechanism, ensuring that the system remains in a known state by regularly requiring a 'kick' from the processor.

Overall, the TPS3110E09DBVR by Texas Instruments is a robust solution for system voltage supervision, offering a mix of features that promote system stability, reliability, and a high degree of protection against voltage anomalies in digital and microprocessor systems.
