CH101-00ABR selection and design context
CH101-00ABR is cataloged as a Ultrasonic Time-of-Flight Sensor in the CH101 family. Its recorded function is miniature ultrasonic time-of-flight range and presence sensor with an integrated processor. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Sensing Range: 4 cm to 1.2 m. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Measurement Rate: Up to 100 samples/s. Confirm system timing margin and the test conditions attached to the published limit.
- Interface: I²C Fast-mode up to 400 kbit/s. Confirm logic levels, signaling mode, host support and required external components.
- Supply Voltage: 1.8 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
Application and qualification considerations
When evaluating this sensor, confirm measurement range, sensitivity, noise, output data rate, interface voltage, calibration needs and mechanical orientation. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for CH101-00ABR
