Part Number: BQ25121 Tool/software: Could you please provide the capability specifications for the BQ25121 in Load Switch (LS) mode? The datasheet details the LDO mode extensively, but the LS mode's current capability is not mentioned explicitly.
Thank…

Hi,
this is my configuration:
// Reset all registers to default twi_tx_register_8(m_twi, BQ25121_ADDRESS, ILIM_B_UVLO_CR, 0x8A ); //reg 9 // Set Reisters twi_tx_register_8(m_twi, BQ25121_ADDRESS, TS_CFMR, 0x08 ); //reg 2 //…
Part Number: BQ25121 Other Parts Discussed in Thread: BQ25892 We currently use the BQ25121 and the BQ25892 in our designs. We now need a charge IC that can handle the following characteristics.
A battery charger to charge a LiPo battery of 630 mAh,…
Part Number: BQ25121 It looks like the BQ25121 handles a lot of the battery protection inherently. It has over voltage, over current, and under voltage (battery cutoff) protection that is usually provided by an external "protection IC." Is there a protection…
Part Number: BQ25121 Hi Sir
May we know if TS pin have no use, how to connect it?
Form DS, Figure 16. TS Circuit Vdr is connect to Vin. but EVB is connect to PMID. which one is correct?
for EVB, it is use 20K VR to be as NTC. May we know how many…
Part Number: BQ25121 Hi,
Working on the newer BQ25121A.
Can't mask some of the faults although PMIC was written to ignore them.
The faults i am referring are :
1. TS falut. - Have written 0x0F to register 2 of the PMIC.
2.BAT UVLO fault. Have…
Part Number: BQ25121 I'm having the issue that the SYS output is not regulating at cold start with a battery insertion. since I'm using the switcher to power the MCU this doesn't get me very far. what I've found is that if I short CD to BAT then it powers…
Part Number: BQ25121 Other Parts Discussed in Thread: BQ25120A , BQSTUDIO Pulling the LSCTRL Pin LOW does not turn off the LS/LDO out.
But when i also write to the PMIC register (MSB of register 0x07u, changed to 0x7C) it does shutdown the LS/LDO. …
Part Number: BQ25121 Hi ,
When working with no battery connected to device, only external 5V power.
On Boot, when PMIC is in default state.
If LSCTRL pin connected to PMIC is LOW then i can't configure the PMIC registers, get some I2C error.
if…
