Power system design often involves making efficient use of scarce resources, such as battery power, available circuit board space, and power supply design. Many applications require the power system to be robust and able to handle high levels of power without failures. Hot swap controllers can help to ensure reliable operation in these challenging applications by providing power control and system protection for sensitive electronics such as LEDs, motors, and other ICs. The UCC2913N is a dual-channel hot swap controller from TI (Texas Instruments) that provides a comprehensive solution for hot-swap applications in a wide range of operating environments, from healthcare to industrial, automotive, and consumer markets.
UCC2913N Features
By providing a dual-channel, high performance hot-swap management system, the UCC2913N provides cost-effective solutions for a variety of power control applications. The UCC2913N features include:
- Two, independently-configurable hot swap channels
- Overcurrent protection and sensing with configurable trip current, typical peak current limit, and fault timing windows
- Wide supply voltage range (3 V to 40 V), overvoltage protection, and undervoltage protection
- Small footprint (5.5 mm x 5.0 mm SSOP-16 package)
The UCC2913N also includes a low on-resistance (155 mΩ typ) n-channel Movable Output FET, distributed gate driver, temperature-compensated current limit and protection circuit, and an integrated start up circuit for enabling the hot-swap channels.
UCC2913N Application Field and Working Principle
The UCC2913N is designed to provide a robust, reliable hot swap solution for applications that require high levels of power control and protection. Typical applications include fan-out power systems, Ethernet and other communications products, automotive and consumer applications. The UCC2913N has the capability to detect and respond to output faults quickly and accurately, making it an ideal solution for applications that must comply with safety regulations.
The UCC2913N works by sensing the power supply voltage and controlling the load by regulating the gate voltage of the MOSFET. When the output voltage exceeds a pre-set threshold, the UCC2913N automatically shuts off the MOSFET and protects the system. This can prevent overvoltage, reverse polarity, overcurrent, and overtemperature conditions from damaging sensitive parts of the power system. The UCC2913N also provides high noise immunity and extensive short-circuit protection.
In applications with multiple outputs, the UCC2913N can be used to control each channel. The UCC2913N uses an adjustable current limit and overvoltage detection to determine when to switch the MOSFET off and protect the system from damage. The device also has configurable low voltage thresholds for overvoltage protection. The channels can be individually programmed using digital input signals or jumpers.
The UCC2913N also includes a comprehensive Start-up Circuit. This circuit monitors the voltage and current of the output and ensures that the output is stable before enabling the MOSFET. If the output voltage is too high, the circuit will lower the output before enabling the MOSFET. This helps to ensure that the output voltage stays within the compliant range, avoiding component damage or system failure.
For applications requiring higher current capability, the UCC2913N can be combined with external FETs and other circuit components, allowing the user to customize the system to meet their specific power system requirements. The device features up to 20 V startup and shutdown, as well as an integrated off-board gate driver for parallel operation.
Conclusion
The UCC2913N is a dual-channel hot swap controller designed to provide a robust, reliable, and cost-effective power management solution for a variety of applications. The device features adjustable current limit and overvoltage protection, temperature-compensated current limit, and an integrated start up circuit for enabling the hot-swap channels. The device can be used with external FETs for applications requiring higher current capability, and can be programmed using digital input signals or jumpers.
