Part Number: BQ25155 Other Parts Discussed in Thread: BQ25190 , BQ25619 , BQ25628
Hello TI team,
We are evaluating a miniature TWS earbud charging architecture using rechargeable Li-ion coin/button cells. BQ25155 and the two-pin…
Part Number: BQ25155 We are using the BQ25155 in a sealed wearable device with no external pushbutton. Our host MCU is powered from the BQ25155, so when MR is asserted the MCU immediately loses power. We need a robust way to initiate a full hardware reset…
Part Number: BQ25155 Hi Experts,
I am supporting a design for TWS earbud using BQ25155. I am trying to calculate the minimum headroom at these charge current 300 mA, 425 mA and up to 500 mA but I cannot find the dropout voltage. Can you help?
Also…
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 Other Parts Discussed in Thread: BQSTUDIO Hi Teams,
We are currently seeing an issue where, during TS function transitions from warm → cool or cold → cool, the charging current remains at fast charge even though the cool flag has…
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?
