OB1203SD-C4R - Renesas Electronics

Description: The OB1203 is a fully integrated optical sensing module for Pulse Oximetry (PPG - photoplethysmography), multi-channel Color Sensing (CS), Ambient Light Sensing (LS) and Proximity Sensing (PS).With the appropriate algorithm, it can determine human heart rate, blood oxygen saturation (SpO2), respiration rate and heart rate variability (a measure of stress). The OB1203 integrates all light sources, drivers, and the sensor elements, in a single optically optimized package.A major application of the device is c

OB1203SD-C4R Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-AN-1203-001) which includes thermal vias, copper pours, and component placement guidelines to ensure optimal thermal performance.
  • The OB1203SD-C4R has a built-in overcurrent protection feature that can be enabled by setting the OCP pin high. Additionally, an external overcurrent protection circuit can be implemented using a sense resistor and a comparator to detect overcurrent conditions.
  • Renesas recommends using a 10uF to 22uF ceramic capacitor with an X5R or X7R dielectric as the input capacitor. The capacitor value and type may vary depending on the specific application and input voltage ripple requirements.
  • The output voltage of the OB1203SD-C4R can be adjusted by connecting a resistor divider network between the VOUT pin and the GND pin. The resistor values can be calculated using the formula provided in the datasheet.
  • The maximum ambient temperature for the OB1203SD-C4R is 85°C, but it can be derated to 70°C for high-reliability applications. It's essential to ensure proper thermal design and heat dissipation to maintain the device's reliability.
