Introducing the TPS3702CX12DDCR from Texas Instruments

The TPS3702CX12DDCR is a high-precision, ultra-low-power, supply voltage supervisor designed by Texas Instruments (TI), a leader in semiconductor solutions. This device is engineered to monitor two system voltages, making it an ideal solution for a wide range of applications, including battery-powered devices, portable electronics, and industrial systems where power efficiency and reliability are paramount.

This supervisory circuit is characterized by its very low quiescent current, typically just 1.8 µA, which is crucial for power-sensitive applications. The TPS3702CX12DDCR operates over a wide supply voltage range, from 1.8 V to 6.5 V, providing the versatility needed to support various logic levels and to be compatible with a broad array of microcontrollers and digital systems.

One of the standout features of the TPS3702CX12DDCR is its high threshold accuracy (±0.5% at 25°C), ensuring precise voltage monitoring, which is essential for protecting sensitive electronic components. The device offers a fixed-sense threshold voltage of 1.2 V, and the second voltage threshold can be set using external resistors, allowing for customization to specific system requirements.

The TPS3702CX12DDCR comes in a small, space-saving 6-pin SOT-23 package, which is beneficial for designs where board space is at a premium. It is also characterized by its fast propagation delay of 20 µs (typical), which allows for quick system response to fault conditions.

Additional features include a manual reset input, which provides a hardware override of the reset output, and the open-drain output topology of the RESET and RESET-bar outputs, allowing for flexible interfacing with other logic components. The TPS3702CX12DDCR also includes built-in hysteresis to prevent false resets and to ensure stable operation under noisy conditions.

In summary, the TPS3702CX12DDCR from Texas Instruments is a reliable and efficient solution for system voltage supervision, combining ultra-low power consumption with high accuracy and versatility. It is a perfect choice for designers looking to enhance system reliability and extend battery life in their electronic products.
