Summary

Torex Semiconductor has released the XC8115/XC8116 Series, multifunction load switch ICs designed for ultra-low power consumption. These new ICs achieve 0µA current consumption during both active operation and standby, making them ideal for battery-powered equipment and energy harvesting systems. They eliminate the need for input or output capacitors, enabling standalone operation and contributing to space-saving PCB designs. The series integrates power line ON/OFF control, typically requiring multiple discrete components, into a compact solution. Specific models offer distinct features: the XC8115 includes externally adjustable soft-start and CL discharge for power sequence control in FPGAs and MCUs, while the XC8116 features reverse current blocking for backup power circuits and supports compact power multiplexer designs. Both models operate up to 105°C, include short-circuit and thermal shutdown protection, and are available in DFN1515-6A (1.5 × 1.5 × 0.38 mm) and SOT-25 packages.

Key takeaway

For hardware engineers designing battery-powered or space-constrained devices, the Torex XC8115/XC8116 Series offers a compelling solution. You should consider these multifunction load switch ICs to achieve 0µA current consumption, significantly extending battery life and reducing PCB footprint by eliminating external capacitors. Evaluate the XC8115 for precise power sequence control in FPGA/MCU applications or the XC8116 for robust backup power and multiplexer designs, leveraging their integrated protection features for enhanced reliability.
