Part Number: BQ24195 Hello!
We are using the BQ24195 chip within a powerbank application.
With loads below 1.7A the chip works correctly, but if the load is higher, I meet with a voltage drop after a few minutes of work. The temperature of the chip…
Hi,
1. Referring to 8.3.1.2 Power Up from Battery without DC Source on the d/s, If only battery is present and the voltage is above depletion threshold (VBAT_DEPL), the BATFET turns on and connects battery to system.
The host may disable BATFET…
Hi Parker,
thanks for your reply . please refer follows for your information.
1. Is this on the bq24195 EVM?
R. No, it is base on our PCB.
2. What are the current register settings for your device? Specifically, I'm interested in the REG01. If…
Hi,
1. REGN is internal LDO regulator. PM100mV ID is the direct power input for the charger.
2. 100mV or 300mV is referenced to VREG (REG04[7:2]).
Thanks,
Ning.
Part Number: BQ24195 The volt of system require 5V 1.5A at least, so it seems that i ll use the boost mode and get the power from PMID pin all the time, my questions are as below

Hi Team,
Regarding the Absolute Maximum ratings of BQ24195 , the Max negative voltage of Vbus and SW pin is -2 V , while the others is -0.3V .
What is the reason for different negative…
Part Number: BQ24195 Hi,
As this Issue is already under discussion, i would like to open this issue again,
I have connected VIN to +5.5V and D+ and D- shorted together and I'm not using any Host Computer to detect the Current Limit.
Still I could…
Part Number: BQ24195 Hi,
I just know the BQ24195 will be working on PFM when the battery is below minimum system voltage setting or charging is disabled. beside of voltage, I also like to know if the output current or charge current is very small, does…
Part Number: BQ24195 Hi
we can't power charger up from shipping mode.
First, we discharge battery to 2.9 V and send ship command to charger by (REG05[5:4] = 00) and disable BATFET (REG07[5] = 1)
Then we plug a stable 12v DC source to Vbus but REGN…
Part Number: BQ24195 Other Parts Discussed in Thread: BQ24190 Dear TI,
we designing BMS based on Bq24195, for reference we following your EVM circuit ( http://www.ti.com/lit/ug/sluua18a/sluua18a.pdf ) ,from that we don't want USB charging mode only…
