The TPS3307-25DGN is a high performance and cost-effective supervisor and reset IC from Texas Instruments. This power management IC (PMIC) is designed to provide a reset signal to the microprocessor (CPU) to reinitialize the system conditions under power-on or power-off conditions. It also offers protection from brown-out and over-voltage conditions. Its features make it suitable for a variety of application fields.

The TPS3307-25DGN has on-chip precision voltage, temperature, and time references, all of which can be applied to various applications. It also includes an internal voltage regulator to stabilize the voltage supply. In addition, it contains an active latch and an open drain output. This enables the supervisor IC to monitor the stability of the system\'s operating environment while providing a reset signal to the microprocessor.

The TPS3307-25DGN is ideal for system reset in laptop computers, PC power supplies, digital TV set-top boxes, and CD-ROM drives. It also offers protection from brown-out and over-voltage conditions that can otherwise be fatal for sensitive electrical components. In addition, it has an internal temperature sensing capability to detect temperature drifts and can be used in a wide temperature range.

The working principle of the TPS3307-25DGN is based on its power management IC\'s ability to monitor the supply voltage and temperature of the system. It does this by comparing the supply voltage to its internal voltage reference, and then giving a reset signal to the microprocessor when the voltage falls below its set level. Additionally, its on-chip thermal sensor is able to detect any temperature drifts and alert the microprocessor accordingly.

The TPS3307-25DGN is capable of handling up to 32 devices in one system, providing a reset signal to all devices. The reset signal can be activated in one of three methods: manual reset, active low-level reset, or deactivated high-level reset. This allows the user to select the reset signal that is most suitable for the system.

In summary, the TPS3307-25DGN PMIC Supervisor is a versatile and cost-effective power management IC that is designed to provide a reset signal to the microprocessor and protect from brown-out and over-voltage conditions. Its features make it suitable for a variety of applications including laptops, PC power supplies, digital set top boxes, and CD-ROM drives. Its on-chip precision voltage and temperature references, coupled with its internal voltage regulator, make it an ideal choice for reliable reset and system protection.
