Key Features
- Single-channel N-channel hot swap control up to 35V enabling safe board insertion and removal in live backplane systems without power disruption
- Adjustable threshold allows customization of overcurrent and overvoltage trip points for flexible protection in diverse power supply designs
- 18-pin SOIC surface-mount package in tape-and-reel packaging simplifies automated PCB assembly and reduces board space versus through-hole alternatives
Applications
The UC2914DWTR is designed for hot-swap and inrush current control in server backplanes, telecom shelves, and industrial rack-mount systems where circuit boards must be inserted or removed while the system remains powered. Its adjustable threshold makes it adaptable to a wide range of supply voltages and load configurations, supporting both 12V and 24V bus architectures. The device is also used in redundant power distribution systems and high-availability computing platforms requiring controlled power sequencing.
