Supervisors, or supervisor integrated circuits, are electronics components utilized in power management applications where it is necessary to realize power control and provide reset supervision functions. The TPS3620-33DGKR is a low-cost, ultra-low-power supervisor designed specifically for power management and performance enhancement in a range of industries.

The TPS3620-33DGKR is a Stand-Alone Unipolar Voltage Supervisor with adjustable threshold, push-pull reset output, low quiescent current, low minimum reset voltage, and a voltage reference accuracy of ±1.4% at +25°C. The device is specified for operation between -40°C to +85°C junction temperatures, and is available in the 5-pin SOT23 package.

The primary application field for the TPS3620-33DGKR is general purpose system power reset generation and power supply monitoring. The device is suitable for use in both commercial and industrial environments, such as embedded applications, personal computers, automation, security systems, and any other applications requiring reliable reset operation.

In its most basic function, the TPS3620-33DGKR monitors a regulated voltage VCC supply, and if the voltage drops below a predetermined voltage threshold, a reset signal is generated. When the voltage is restored to the normal level, the reset signal is then removed and the system resumes operation.

The device features a selectable reset output type (push pull or open drain) which eliminates the need for addition external components, an adjustable reset voltage threshold from 1.2V to 3.8V, a programmable reset time delay to prevent false triggering, and a reset status open-drain output.

The TPS3620-33DGKR also includes an active reset output, which is a feature unique to the TPS3620-33DGKR. This active reset output provides an early warning signal prior to triggering a system reset, allowing the system to be properly managed and/or react to an impending system reset event.

In addition to these detailed monitoring qualities, the TPS3620-33DGKR also has excellent power saving capabilities. Its ultra-low-power operation enables extended battery life, and its low quiescent current and low minimum reset voltage makes it well suited for a wide variety of applications.

In conclusion, the TPS3620-33DGKR is an ideal solution for applications requiring reliable reset operation while maximizing power savings and minimizing load on the system power supply. With its adjustable reset threshold, selectable reset output types, programmable reset time delay, and active reset output, the TPS3620-33DGKR provides a flexible and reliable solution for any power management system.
