BQ25173: STAT LED BLINKING

Part Number: BQ25173

STAT LED blinks with/without battery connection. My rechargeable battery is 8.4V.

Below steps are also followed to recover STAT Led blinking:

Fault Mode The fault conditions are categorized into recoverable and nonrecoverable as follows:

• Recoverable, from which the device should automatically recover once the fault condition is removed: – VIN OVP

• Nonrecoverable, requiring pin or input supply toggle to resume operation: – OUT OCP – ISET pin short detected

still STAT Led is blinking.

Circuit enclosed for your refernce.

  • Hi

    Couple of things to check:

    1.) Check the output voltage do you seen any voltage overshoot or oscillation?

    2.) If you reduce the output voltage does it change behavior?

    3.) ISET will indicate output current check the voltage at the pin for overshoot at turn on?
