Product Overview: Texas Instruments TPS3123J12DBVR

The Texas Instruments TPS3123J12DBVR is a highly reliable, low-power supervisor circuit designed to monitor voltage levels in digital systems and provide a reset signal whenever necessary. This device is particularly suitable for battery-powered applications due to its low energy consumption and small form factor. The TPS3123J12DBVR ensures that microprocessors, microcontrollers, and other digital systems reset properly during power-up, power-down, or brown-out conditions.

Key Features

• Supply Voltage Monitoring: The TPS3123J12DBVR monitors the supply voltage (V_DD) and keeps the system in reset until the V_DD voltage reaches the factory-programmed threshold, ensuring stable system operation.
• Programmed Delay: It features a programmable delay time provided by an external capacitor, which allows designers to set the reset timeout period according to their system requirements.
• Low Power Consumption: With a typical quiescent current of only 9 µA, this device is optimized for power-sensitive applications, helping to extend battery life in portable devices.
• High Accuracy: The TPS3123J12DBVR offers high threshold accuracy (±1.5% at 25°C), which is crucial for reliable operation in systems where precise voltage monitoring is necessary.
• Manual Reset Input: A manual reset input is provided, allowing the reset to be triggered with an external signal for added system control and diagnostics.
