  • TPS8802: TPS8802 VMCU Issue – Unable to Generate 3.3 V VMCU Despite MCUSEL 3.3 V Configuration

    Part Number: TPS8802 TPS8802 Not Generating 3.3 V VMCU Despite MCUSEL Configuration We have observed this issue multiple times with the TPS8802, where the device is unable to generate the expected 3.3 V at VMCU even though the MCUSEL configuration is…

  • TPS8802: Power Management and Stability Issue under Low Battery Voltage ($2.2\text{V} - 3.6\text{V}$) in TPS8802 and TPS63900 Integration

    Part Number: TPS8802 Other Parts Discussed in Thread: TPS63900 Hello, I am designing an optical smoke detector using the TPS8802 AFE (Analog Front-End) and smoke sensor driver. In my design, I want to use both IR and Blue LEDs, as well as perform buzzer…

  • TPS8802: TPS8802 – VBST is not reaching/getting as Programmed 15 V and VBST Error we are getting due to that

    Part Number: TPS8802 Dear TI Support Team, We are facing an issue with the **TPS8802 IC**, where the **VBST boost voltage is not being generated as expected**. Our measured voltages are: * **VBAT = 3.2 V** * **VINT = 2.3 V** * **VBST = approximately…

  • TPS8802: TPS8802 Interrupt

    Part Number: TPS8802 Hi, I was wonder if you can set up the TPS8802 to interrupt my processor when smoke is detected. It seems like using the Interconnect bus alarms from other TPS8802 can cause an interrupt but it also seems as if the MCU needs to…

  • TPS8802: TPS8802

    Part Number: TPS8802 Tool/software: Hi There, I was researching about the smoke detector technologies available out there and I came across the detection based on SMD(Sauter Mean Diameter) of aerosol. Can anyone please confirm if TPS8802 support this…

  • TPS8802: Schematic Review

    Part Number: TPS8802 Hi! I'm designing in the TPS8802 and would like to have my schematic reviewed. I do also have one question. For the IR LED and operating at 100mA, you would need a 10W 1K resistor??? TPS8802.docx Thanks so much! John

  • TPS8802: Application issues.

    Part Number: TPS8802 Other Parts Discussed in Thread: MSPM0L1306 Tool/software: Hi Team, The customer is using MSPM0L1306+TPS8802 for smoke sensor products and would like to know what algorithm is being used? What algorithm resources can be made public…

  • TPS8802EVM: TPS8802

    Part Number: TPS8802EVM Other Parts Discussed in Thread: TPS8802 Tool/software: In the TPS8802, TI is using 1 photodiode and 2 LEDs but there are different configuration with 2 photodiodes and 2 LEDs. Why is TI using 1 photodiodes only? and how does both…

  • TLV9061: TPS8802

    TI Thinks Resolved
    Part Number: TLV9061 Other Parts Discussed in Thread: TPS8802 , TLV906X Tool/software: HI all. We are trying to do the POC of Dual-Ray Smoke Detector with the TPS8802 and MSPM0 MCUs and we are referring to the document provided on TI site. there is one…

  • TPS8802: How do I connect VBST and VLX pins

    Part Number: TPS8802 Tool/software: Hello Everyone, I was using TPS8802DCPR in one my designs. I was wondering how do I connect VBST and VLX pins if the boost converter is not used. In data sheet's pin description it says "Boost converter feedback…
