Hello,
The 20ms delay from PMID should be good for giving the extra time for the LDO to fully power-up. Another alternative is to look into the BQ25155 which is a pin-2-pin and firmware compatible device, and is a newer device which has a faster startup…
Part Number: BQ25150 Hi Team,
in the DS on page 24 it says
The host may change the reset behavior at any time after MR going low and prior to the MR_HW_RESET timer expiring. It may not change it however from another behavior to a HW reset (Power Cycle…
Part Number: BQ25150 Other Parts Discussed in Thread: BQ25155EVM , BQ25155 , TEST We are using BQ25150 in one of our boards
We are facing issue with the values of two registers in the IC
Content on reset as per the Datasheet ICHG_CTRL (Address = 0x13) [reset…
Sorry to ask a related question on the resolved thread. I'm just exploring possible future modifications to support multiple chips.
Currently, my C4 (ADCIN) in BQ25155 is connected to GND directly. What if I route C3 (IMAX for BQ25150) through C4 and…
Part Number: BQ25150 Other Parts Discussed in Thread: BQ25157 , BQ25155 Hi Team, Is the difference between BQ25155 and BQ25157 only default setting of registers? Best Regards, Yaita
Part Number: BQ25150 Hi,
i am powering BQ25150 from battery (own standalone pcb without I2C connections).
1) When pressing /MR line down for a period battery voltage is seen on PMID. However, LS/LDO output is showing 0V.
2) When powering same pcb from…
Hi Garrett, Thank you for taking a look at our waveforms. With the /MR pin floating (not connected to the MCU) we are indeed able to enter ship mode upon battery insertion with a current consumption in the low uA range, as expected. After investigating…
Part Number: BQ25150 Hello,
We are using the BQ25150 to charge a lithium battery. All is working well. The only issue we are observing is when we want to use the PG and INT pin in interrupt mode (with pull up from the MCU). When we want to put the 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…
