Part Number: BQ25155 Other Parts Discussed in Thread: BQ25190 , BQ25120A Hi, I'm currently looking for an alternative to my charger/regulator with double output voltage and shipping mode functionnality.
My product needs a 1.8V to power up sensors/MCU…
Part Number: BQ25155 Tool/software: I am using I2C to read out the Vbat value on register 0x42. I can get 2 bytes out of the read MSB followed by LSB. When reading the register 0x43 that suppose to contain LSB it does not match the first reading LSB.…
Part Number: BQ25155 Just a question for furture clarification on a previous posting: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1477919/bq25155-ls-ldo-unused
When the LS/LDO is unused on the BQ25155…
Part Number: BQ25155 Hello,
We are looking for a battery charging and protection IC where the losses during active charging can be minimized. The current range only needs to work up to ~500mA and our input can provide some voltage/current limiting if…
Part Number: BQ25155 For the PBat power dissipation. If the load current is 1.5 A and the max Battery FET RdsOn = 135 mOhm. Is the power dissipation 303750 mW?
Part Number: BQ25155 Hello,
I have some questions about the BQ25155 interface:
Can you confirm that there is reverse voltage protection built into the device? (for example if the battery has been turned over during the assembly or replacement) …
Part Number: BQ25155 Tool/software: Hello, I'm going to use BQ25155 part in my new design.
1) If input voltage is 3.3V and desired PMID output voltage is 5V. whether it will work?
2) If BAT voltage is 4.2V and PMID voltage is <4.2V, whether it will…
Part Number: BQ25155 Tool/software:
Hello,
We are designing a space constrained device that uses a BLE MCU and an AFE for taking measurements. The BLE MCU can operate from 1.7 - 3.6 V, while the AFE requires 3.3 V.
We want to use the integrated…
Part Number: BQ25155 With BATT connected, VIN (5V) was turned OFF. ADC_IIN_Current shows approximately 330mA. Why is it flowing even though there is no input from VIN?
When VIN is in the ON state, the current value is approximately normal.
