TPS259260DRCT Datasheet/PDFTPS259260DRCT is a power management integrated circuit (PMIC) – Hot Swap Controllers from Texas Instruments, operating from a supply voltage range of 2.5 V to 5.5 V. It enables a wide range of applications from consumer, computing and networking to industrial, communications and medical fields. The TPS259260DRCT Hot Swap Controller is particularly suitable for gigabit or larger computer applications where plenty of power is delivered over a limited amount of pin space.
Overview
The TPS259260DRCT Hot Swap Controller is a current-limited on-board power distribution device which provides maximum protection to the system during power-on, as well as controlling power to non-critical load devices while operating. It is designed to manage the power delivery to and from any source which is connected to the system, either directly or over a bus. It operates as a power management IC (PMIC) in the voltage-based hot-swapped system with relay or passive load switching.
Working Principle
The Hot Swap Controller provides inrush limiting and current limiting protection for any voltage supply. It regulates the power delivery from the power source to the downstream components. The power sourced from the system can be either direct or from an external supply, such as a wall plug or battery. The TPS259260DRCT DC/DC provides a controlled current to the downstream loads. The current is regulated by an advanced current-limited system that prevents the downstream loads from receiving an excessive current, thus protecting the system.
In applications that require a larger power delivery capability, the device can be used with relays or an external load switch circuit. This allows the ability to support current up to 8 A, providing protection during power-on and maintaining the current during normal operation.
Control Features
The TPS259260DRCT DC/DC Hot Swap Controller provides various control features that are beneficial in many electronic devices. The device supports two input voltage ranges of 2.5 V to 5.5 V and 5 V to 15 V, allowing the device to be connected directly to almost any source. Additionally, the Hot Swap Controller has a programmable current limit that allows the user to set the maximum current that can be drawn from the system. The current limit can be configured up to 8.5 A and is adjustable via an external resistor.
The TPS259260DRCT further includes protection features that are beneficial in any power system. The device has programmable over-current protection and over-temperature protection. Additionally, the Hot Swap Controller\'s MOSFET switch is protected from short circuit, overtemperature, and can be configured to be either synchronous or asynchronous.
Applications
The TPS259260DRCT Hot Swap Controller is suitable for any voltage source up to 8.5 A. It can be used in various applications such as consumer, computing and networking, industrial, communication and medical fields. The device can also be used in applications where the power delivery needs to be managed, such as AC adapters for laptops, pagers, PDAs, or any other similar device. The Hot Swap Controller is also suitable for systems that require multiple devices to be powered simultaneously, and for systems requiring reliable and cost-effective over-current protection.
Conclusion
The TPS259260DRCT Hot Swap Controller is an advanced power management integrated circuit (PMIC) designed to provide maximum protection to any electricity supply while controlling the power delivery to any connected load. It is suitable for applications needing reliable and cost-effective current limiting and over-current protection, as well as providing current up to 8 A. The Hot Swap Controller is suitable for applications in the consumer, computing, networking, industrial, communication and medical fields.
