UCC2913DTRG4 Application Field and Working PrincipleUCC2913DTRG4 is an integrated circuit, namely a hot swap controller that resides in the family of PMIC (Power Management Integrated Circuits). This particular hot swap controller unit is manufactured by Texas Instruments and is widely used in the field of telecommunication, industrial and automotive systems. Generally, hot swap controllers are used to regulate voltage and current in applications that have a varying load or require soft-startup for monitored power regulation.Due to its inherent flexibility and efficient power management, the UCC2913DTRG4 hot swap controller makes it a good option for applications needing reliable and cost-effective electronic power management. This integrated circuit has several distinct features which make it one of the most preferred hot swap controller ICs among the electronic engineers. It has an adjustable 1.2A overcurrent limit, 3.3 to 36V output range, logic-controlled overcurrent protection, fast response, and programmable bussed current monitoring.The UCC2913DTRG4 operates on a maximum current of 1.2 A and has a 2.8V to 7.2V typical on-chip supply voltage. This hot swap controller has a maximum on-chip control supply voltage range (VCC1) of 2.7 to 6.5V, making it suitable to operate in most systems. Additionally, its high efficiency operation, low quiescent current, and low dissipation makes it a power-efficient IC that can fulfill most power regulatory needs.The UCC2913DTRG4 hot swap controller has a typical operating temperature range of 0°C to +85°C. It has a +36V absolute maximum output voltage and a +36V absolute maximum guarantee maximum overcurrent protection trip level. The die-cast tin-lead-silver (Sn99.3Ag0.7) package used for this hot swap controller has a power dissipation of 0.75W and is RoHS-compliant.The working principle of the UCC2913DTRG4 hot swap controller is based on two main operational modes of operation, namely sense delay mode and sense-on mode. In the sense-delay mode, the controller monitors the voltage present on the VCC1_ROOT pin, waiting for it to reach its desired level. When the voltage reaches this level, the controller will enable the high-side FET to turn on, providing a path to the load. In the sense-on mode, the controller will monitor the voltage of VCC1_ROOT immediately, and if it reaches the desired level, then the high-side FET will turn on to provide the path to the load.The UCC2913DTRG4 hot swap controller is a versatile IC that is capable of performing many power regulatory duties like power good monitoring, power enable and control, programmable current limit, over-current protection, and low impedance discharge path. This integrated circuit provides superior performance than most other hot swap controller ICs while performing all these duties in highly reliable and cost-effective manner. Furthermore, its flexibility, durability, and reliability make it the perfect choice for many applications requiring reliable power regulation and monitoring.
