BQ25173: Abrupt increase in Charging current when input power switched multiple time.

Part Number: BQ25173


Tool/software:

Hello Team,

We are Using BQ25173 for charging  2 series ADCR-T02R7SA505MB 2.7 V Supercapacitor with 30mA Iset. The input supply voltage to BQ25173 is 5V. It works fine during normal supply ON-OFF cycle. However, if input is switched ON-OFF 4-5 times with 1 sec duration (consider it as flickering of power supply), charging current suddenly increases to 800mA. 

Is this known limitation and is there any solution to this problem ? 

Find following circuit diagram for your reference (VCC_4VOUT = 5V).
