TPS3707-33DGNRG4 by Texas Instruments

The TPS3707-33DGNRG4 is a state-of-the-art supervisory circuit designed by Texas Instruments to provide precision voltage monitoring and microprocessor supervisory functions. This device is tailored to ensure reliable operation and system integrity by monitoring the supply voltage of digital systems. It is particularly suitable for applications that require a high degree of stability and accuracy, such as industrial control systems, portable devices, and smart electronics.

Housed in a compact 8-pin MSOP (DGN) package, the TPS3707-33DGNRG4 offers a fixed-sense threshold voltage of 3.3V, which is ideal for monitoring 3.3V power supply rails. The device features a low supply current, which makes it an excellent choice for power-sensitive applications. With a wide supply voltage range from 1.8V to 6.0V, it provides versatile usage across various platforms and applications.

One of the key features of the TPS3707-33DGNRG4 is its integrated watchdog timer, which can be used to reset a microprocessor if it fails to strobe within a preset time frame. This function is crucial for systems that cannot afford to have a processor hang or operate unpredictably. The device also offers a manual reset input, which allows for an external trigger to initiate a system reset.

The output of the TPS3707-33DGNRG4 is an active-low reset signal, which remains asserted for a minimum of 200ms after the supply voltage returns above the threshold level. This ensures that the system has sufficient time to stabilize before resuming operation. Additionally, the device is characterized for operation over the free-air temperature range of -40°C to 85°C, which means it can withstand harsh environmental conditions.

For designers and engineers looking for a reliable supervisory circuit that can maintain system integrity through precise voltage monitoring and reset functions, the TPS3707-33DGNRG4 from Texas Instruments is an excellent choice. Its robust feature set and compact form factor make it a versatile component for a wide array of electronic products.
