TPS3808G33MDBVR by Texas Instruments

The TPS3808G33MDBVR is a high-precision programmable delay supervisor from Texas Instruments, designed to provide reliable monitoring of voltage supplies in digital systems. This micro-sized, low-power integrated circuit is ideal for a variety of applications including portable and battery-powered electronics, microcontrollers, and digital systems that require precise voltage supervision to ensure proper operation and protection.

This voltage supervisor is part of the TPS3808 series and comes in a compact SOT-23-6 package, making it suitable for space-constrained applications. With a fixed-sense threshold voltage of 3.3V, the TPS3808G33MDBVR is tailored for systems that operate around this voltage level, ensuring that devices are not only powered on at the correct voltage but also protected from conditions such as brownouts.

One of the key features of this product is its programmable time delay, which allows users to set the delay period before the output is enabled after the input voltage exceeds the threshold. This is particularly useful in complex systems where a controlled power-up sequence is required. The delay can be programmed via an external capacitor, providing flexibility to meet different system requirements.

The TPS3808G33MDBVR also boasts a manual reset input, enabling the system to be reset manually without the need to cycle the power. This feature enhances the control and safety of the system, allowing for immediate intervention in case of system anomalies.

Additionally, the device offers a low quiescent current of only 2.5 µA (typical), which is critical for battery-powered applications where power conservation is a priority. It also provides an open-drain output, which supports both push-pull and open-drain configurations, giving designers the flexibility to integrate the supervisor into a variety of system architectures.

With its robust feature set, the TPS3808G33MDBVR by Texas Instruments stands out as a versatile and efficient solution for voltage supervision in digital systems, ensuring that devices operate reliably and are adequately protected from power-related issues.
