The TPS3306-18DGKR is a general purpose supervisor integrated circuit (IC) designed to monitor voltage levels in power supplies and other circuits and reset the system when the voltage level goes outside a predetermined range. It is a part of Texas Instruments (TI) power management integrated circuits (PMICs) series called Supervisors. The device is also known as a "master supervisor". The TPS3306-18DGKR can be used in a wide range of applications, such as voltage supervision in computers, game consoles, digital audio systems, and embedded applications.

The TPS3306-18DGKR consists of two devices integrated into the same package: a supervisor circuit and a reset output timer circuit. The supervisor circuit is used to monitor the system voltage, while the reset timer circuit is used to generate reset pulses when the voltage falls outside the acceptable range. The reset timer circuit can be externally triggered with a low-voltage input or it can be triggered by the supervisor circuit when the voltage falls outside of its acceptable range.

The TPS3306-18DGKR is designed to trigger a system reset when the voltage level falls below a predetermined minimum level, or when the voltage rises above a predetermined maximum level. The device is also designed to monitor voltage levels in several distinct power supply lines. It has two monitoring voltage lines: one for the main system power and one for a backup line. The supervisor can monitor both lines simultaneously and trigger a reset when either line falls outside of the predetermined range.

The TPS3306-18DGKR is a low-power device, consuming a maximum of 0.2mA. It has a wide input voltage range of 2.5V to 5.5V and an operating temperature range of -40°C to +125°C. The device also features a low-power/sleep mode, in which the reset timer is disabled, allowing the supervisor to monitor the input voltage levels while consuming a minimal amount of power.

The TPS3306-18DGKR provides a high level of reliability and safety, as the device is able to detect and reset the system in the event of a voltage threshold violation. Additionally, the device is designed with a power-on reset circuit, which ensures the system resets to a safe and known state upon power-up.

The TPS3306-18DGKR is an important part of any power supply system and is used to maintain its safe and reliable operation. With its wide input voltage range, high temperature operating range, and low-power/sleep mode, the device is suitable for a variety of applications. By monitoring the voltage levels in a power supply system and initiating a reset when necessary, the TPS3306-18DGKR ensures that the system is operating safely and performs as expected.
