Winning Combinations to Design Faster

High accuracy distance detector for security applications

Measure distance via Time of Flight technology

Time of Flight (ToF) technology has gained popularity and has been widely adopted for various applications. This system incorporates the ISL29501 ToF IC to provide a high-performance solution that is easy to design and control, while delivering accurate wide range distance measurements.

Optimized for handheld applications, this design includes the RA2A1 MCU. The MCU’s analog support allows simple implementation of USB charging of a Li-ion battery. Voltage and current can also be monitored and controlled with real-time feedback, while charging mode can be adjusted as required.

System benefits:

  • ToF with long range measurement distance (more than 10m)
  • MCU-based lithium battery management. Includes pre-charging, constant current (CC), current voltage (CV) charging modes, overcurrent, overvoltage, overheating protection
