Product Overview: TPS3808G12DBVR by Texas Instruments

The TPS3808G12DBVR is a high-precision programmable delay supervisory circuit designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This small-sized, low-power device is an essential component for monitoring voltage supply levels in microcontrollers, microprocessors, and other digital systems that require voltage supervision for reliable operation.

Encased in a compact 6-pin SOT-23 package, the TPS3808G12DBVR offers a fixed-sense threshold voltage of 1.193 V, which is meticulously designed to monitor a 1.2 V supply voltage. However, its flexibility is one of its key features, as it allows users to program the delay time before the reset is de-asserted, ensuring that the system has adequate time to stabilize.

One of the standout features of this supervisory circuit is its low quiescent current, typically 3.0 µA, making it an ideal choice for battery-operated and low-power applications. Moreover, the TPS3808G12DBVR boasts a wide supply voltage range from 1.7 V to 6.5 V, catering to a variety of power requirements and ensuring compatibility with numerous system architectures.

This device also includes a manual reset input, which provides a straightforward method for initiating a system reset. This feature is particularly useful for debugging and system maintenance, enhancing the overall utility of the circuit. Furthermore, the TPS3808G12DBVR has a built-in watchdog timer, which serves as an additional layer of system protection by monitoring the system's operation and initiating a reset if it detects any malfunction or abnormal activity.

TI's commitment to quality is evident in the TPS3808G12DBVR's performance, with its high accuracy of threshold voltage (±1.5%) over the entire temperature range of -40°C to 125°C. This precision ensures that the device can operate reliably in diverse environmental conditions, making it suitable for a wide range of industrial and consumer applications.

In summary, the TPS3808G12DBVR from Texas Instruments is a versatile, reliable, and energy-efficient voltage supervisor that is an indispensable component for any system requiring precise voltage monitoring and robust protection features.
