Part Number: BQ24130 Hi Team:
I have some question on BQ24130 with a super charging solution on customer side design spec: 4V-12V input&4.2V@480mAoutput charging spec, the circuit is as follows:
the question are:
1. About charge current waveform…
Part Number: BQ24130 Hi
I have and question to the datasheet.
Page 4 is using the definition V(ireg_chg) but it is not explained what this value describes (?) Where can I measure this signal?
Part Number: BQ24130 Customer is using the BQ24130 for an intrinsically safe application. The BAT sense line of the charger is connected to the battery pack. This is required to compensate for the forward drops of 3 series diodes which are present inside…
Part Number: BQ24130 Hi,
Our customer is using BQ24130 for charging super capacitor.
They have a issue.
Inrush current (2A) has happened for about 500ms when start up charger.
There is no Vin voltage spike at that time.
Only for issue when connect super…
Part Number: BQ24130 Hi Team, I would like to get your comment on this layout design of the customer using BQ24130 by placing it on the bottom layer and also connecting AGND and PGND (Named RTN in the image) using a 0 Ohm resistor. They use a 0 Ohm resi…
Part Number: BQ24130 Hi
the customer asked current regulation accuracy specification if there is no Schottky diode with SW node?
in our electrical characteristics, our current regulation is measured with Schottky diode.
And, what's the purpose of this…
Part Number: BQ24130 Hi
My customer designed BQ24130 for supercap application but they measured the charging current will jump during charging process.
See below B area the charging current is higher 18mA compared to A area.
Ch1: 5Vbus
Ch2: Vbus curr…
Part Number: BQ24130 Customer is using BQ24130 for an intrinsically safe application. The 2 cell battery pack will have 3 series diodes in the charging path and the return will be connected from the diode outputs back to the BAT sense line. The output…
Part Number: BQ24130 Other Parts Discussed in Thread: TPL0102-100 , , BQ24765 , BQ24640 Hi,
I would like to verify if BQ24130 can be digitally controlled using digital potentiometer like TPL0102-100.
Part Number: BQ24130 Dear all,
I met a problem when using BQ24130 in charging for a Super capacitor.The output charging current does not meet the current I set. For example,when CMOD is set to low,and Viset2=2V, the sense resistor is set to 100mΩ,the…
