BQ21061: Single-Cell Charger IC BQ21061

Part Number: BQ21061


Hello E2E Team,

I am having problem using BQ21061 single-cell charger; usually, no problem with TI Parts.
This is my first-time in years!

Please share your experience if anyone has used this device before and seen similar problems.

List of problems:

1. When a single-cell Li-Ion cell, 3.7V is connected between BAT1/2 and GND, there is NO voltage at PMID1/2.
2. There is NO voltage at VDD.
3. While the battery is connected, the charger draws ~20mA from the cell

I look forward to hear for you.

Thanks,

Raymond
