Texas Instruments TPS8802EVM Smoke/CO Alarm Evaluation Module (EVM)
Texas Instruments TPS8802EVM Smoke/CO Alarm Evaluation Module (EVM) is used to evaluate the TPS8802 smoke and CO detection analog front end and power management IC. The evaluation module allows easy connection from the TPS8802 to a user-supplied photoelectric chamber and carbon monoxide sensor. The Texas Instruments TPS8802EVM GUI interfaces with the evaluation module to quickly evaluate the photo amplifier, LED driver, CO amplifier performance, and static system power consumption. For a more thorough evaluation, an external microcontroller can be connected to the evaluation module to create a prototype smoke detection system.
