TPS2557DRBR

The TPS2557DRBR is a high-side power distribution switch specifically designed for dual-core CPU applications. This particular PMIC, or power management integrated circuit, is designed to operate in a dual-core CPU environment and provides an efficient and cost-effective means of distributing power within the system. The TPS2557DRBR is capable of providing up to 4A of current on each output, supporting up to 25V on each of its four channels.

The TPS2557DRBR is designed to be used in a variety of applications including automotive, telecommunications, consumer electronics, battery-powered devices, and military/aerospace applications. It is well-suited for both in-system and board-level applications, allowing the user to optimize their system architecture and increase power efficiency. The power switch also features a low-power standby mode, allowing the user to enter a lower power state when the system is not in use.

The TPS2557DRBR is a true low-side power distribution switch; it is intended to be used in multi-phase power supply designs and switches the current between two or more voltage paths in a cost-effective manner. The integrated control logic and drivers allow the device to be easily configured for a wide range of power requirements, and the low-side driver makes it ideal for use in space-constrained applications.

The TPS2557DRBR utilizes a proprietary MOSFET-based driverless architecture to provide an accurate current load to support up to 4A of load on each output. The device includes two high-side N-channel MOSFETs and two low-side P-channel MOSFETs that can be operated independently or in parallel to provide a total current load of up to 8A. The output current is controlled by a voltage regulator and the load is sensed by an integrated current shunt regulator.

The TPS2557DRBR also includes an on-chip temperature monitoring circuit and gate driver for controlling the temperature of the device. The on-chip temperature monitoring maintains an accurate temperature profile when the device is operating and adjusts the gate voltage to ensure a reliable switching action. The on-chip gate driver allows for under-shoot/over-shoot protection, ensuring a safe and reliable power supply operation.
