TPS2300IPWG4 application field and working principle

The TPS2300IPWG4 is a high-performance hot swap controller used to control the power supply to circuit elements in various applications. It enables removal and replacement of powered boards without disruption of operation. It is a quasi-reset circuit used with externally powered devices. The TPS2300IPWG4 provides idle line switching, enable/disable control, and output voltage controlling with input voltage monitoring.

Application Fields

The TPS2300IPWG4 is used in various applications as it is suitable for a wide range of applications. For example, it can be used in industrial applications such as to generate hot swap inputs on DIN rails, or general consumer electronic equipment such as tablet computers. Other applications the TPS2300IPWG4 is suitable for include:

• White goods
• High performance computing
• LED lighting
• Power over Ethernet (PoE)
• Power management ICs
• Telecommunications

Working Principle

The TPS2300IPWG4 operates by turning on devices when a power source, such as a main supply, is present and providing a safe shut down of the device when it is no longer needed. When power is present, the TPS2300IPWG4 acts as a quasi-reset circuit. Quasi-reset circuits are used with externally powered devices to detect when input power has been removed or has dwindled below the factory preset threshold voltage, and then initiate the device reset routine.

The TPS2300IPWG4 monitors the input voltage from the main voltage supply and the output voltage from the device. Upon detecting the input voltage has dropped below the preset threshold voltage for a preset time duration, the TPS2300IPWG4 de-energizes the output, which signals to the device to reset. This prevents any permanent damage to the device.

In conclusion, the TPS2300IPWG4 is a hot swap controller used in a wide range of applications that provides idle line switching, enable/disable control, and output voltage controlling with input voltage monitoring. It operates by turning on device when a power source is present, and providing a safe shut down of the device when it is no longer needed.
