The TDE1898RFPT is a power management integrated circuit (PMIC) that provides a complete integrated solution for providing power to and controlling circuitry on a system board or applications. It is a power distribution switch and load driver that is designed to provide voltage regulation, current sensing, and switching for up to three output channels of regulated power for driving loads.

The TDE1898RFPT incorporates an efficient architecture that enables closed-loop control of multiple voltage rails while also managing a low thermal profile. The power distribution switch has an input stage which requires an input voltage of 2.7V to 12V, and four outputs of 3.3V, 1.2V, 0.5A and 0.1A. It also features a current-limit output to provide additional protection for the loads it is driving.

The TDE1898RFPT also features an on-chip temperature sensor circuit that monitors the junction temperature while also providing additional features such as thermal depletion, over-current, over-voltage and under-voltage protection. The TDE1898RFPT is a low-cost, low-power solution that makes it ideal for use in applications such as low-power, low-voltage portable systems such as smartphones and tablets.

The TDE1898RFPT utilizes an adaptive voltage scaling (AVS) technique to provide superior power efficiency and thermal performance. The AVS system adjusts the operating frequency of each output in an effort to maintain optimal efficiency, thermal performance, and peak performance. It also tracks the supply voltage of its associated rails to allow for greater protection from voltage disruptions.

To further enhance its power management features, the TDE1898RFPT provides a number of different load control algorithms. These algorithms provide a number of benefits, including the ability to measure current, voltage and temperature to ensure proper load regulation. These algorithms further allow the TDE1898RFPT to perform more efficient power conversion and regulation, providing better performance than a traditional multivibrator-style voltage regulator.

In addition to its power distribution and load control features, the TDE1898RFPT also provides a number of configurable features. Its integrated digital interface is capable of interfacing with an external host or a control processor, allowing users to customize control settings, such as over-voltage, over-current, and temperature settings. The TDE1898RFPT also provides a wide range of interrupt signals for events such as over-current, over-voltage, under-voltage and temperature out of range, making it a great choice for protecting a system from unexpected power or voltage events.

The TDE1898RFPT is an ideal power management solution for a wide variety of applications, including portable systems and industrial equipment. Its comprehensive protection and power distribution features, combined with its flexible configurability, make it an excellent choice for designers looking to implement a reliable and robust power management solution.
