The TPS3307-18DR is a voltage supervisor with a wide range of application fields and working principles. In terms of application fields, the device is widely used in medical and industrial systems, automotive, and communications equipment due to its precision voltage regulation and reset delay features. As for working principle, the supervisor maintains a regulated VCC output and monitors system power. When the input power supply voltage level drops below a predetermined threshold (as defined by the SET pin), the output is reset, allowing the system to re-power itself.

In terms of actual architecture, the regulation voltage of TPS3307-18DR supers is provided by an internal band gap reference. Additionally, the device has an internal comparator that drives the RESET signal output, which can have active low or active high operation. The reset signal can be kept active until a minimum width has elapsed, as defined by the RESET width pin. Additionally, the TPS3307-18DR features a power-on reset signal, as well as the ability to perform manual reset.

The device can operate over a wide input supply range, from 3.75 V to 28 V, and can handle output loads of up to 1 A. The device also features pin and component options to fine-tune the regulation voltage, such as a SET pin for setting the reset threshold and an ADJ pin for setting the regulated voltage. Furthermore, the device includes thermal protection, which will shut down the output if a certain temperature is reached.

In short, the TPS3307-18DR is a voltage supervisor with accurate voltage regulation and reset delay features. The device is well-suited for use in a variety of systems, from medical and industrial to automotive and communications. The device is equipped with a band gap reference for the regulation voltage, as well as a comparator for the RESET signal. It can operate over a wide input supply range, and features pin and component options for fine-tuning the output. Additionally, the TPS3307-18DR features thermal protection.
