BQ25150: Bq25150

Part Number: BQ25150
Other Parts Discussed in Thread: BQ27426

Hello  Arelis Guerrero,

 
Hi Team

1. Here is the scope captured image at Battery (BAT) terminals.

a. Yellow waveform is IN voltage to BQ25150 IC.

b. Blue waveform is Output voltage at BAT terminals.

Yellow waveform (Vupper 1 =5.2550V , freq1 =11.355khz ,Vlower1 =4.2849V)

Blue waveform(Vlower 2 = 1.579V , Vupper2 = 2.6694V , freq2 = 1.3603khz)  
 
Plz find below image of bq25150_2.
2. Below is the schematic of BQ25150 and BQ27426 fuel gauge.

a. Checking Input voltage across C34 capacitor (IN) and the Output voltage across C39 capacitor (which is connected to BAT terminal through R39).
  Plz find below schematic of bq25150 and bq27426.
