Part Number: BQ24078
Hi Sir,
WOuld you pls help questions for bq24078, thanks.
a)What would be the maximum fast charge current allowed to be set under USB500 mode?
b)When the Riset of EVM is set to be 1800ohms, the max fast charge current is about 470mA…
Part Number: BQ24078 Hi Sir,
Would you pls help review schematic for bq24078?
And pls help to check if Iset and ILIM resistors need to modify.
Vin=0.9A @5V; battery capacity: 880mA, charge done:2~3hrs.
Thanks, Ian.
Part Number: BQ24078 Hi Sir,

Thanks, Ian.
Part Number: BQ24078 I am using a constant voltage sink with a programmable voltage to mimic the system battery that connects to BQ24078 BAT terminals, and monitor VOUT versus instantaneous VBAT voltages. This is a critical parameter in our system, the…
Part Number: BQ24078 We have observed that the BQ24078 in our charger can enter suspended charging mode when the battery's NTC exceeds resistance equivalent to 50C. Charging then resumes once the temperature drops below the limit plus a certain hysteresis…
Part Number: BQ24078 Other Parts Discussed in Thread: TPS3779 , BQ24075 Dear support team
I would like to build a battery charger incl. power path management with the BQ24078. As this chip does not feature an under-voltage protection (prevent discharging…
Part Number: BQ24078 Dear TI engineers~
There is a question about BA24078. On my own board, when the adapter is plugged in, both SYS and Vbat are normal, and the performance of each pin is normal. After unplugging the adapter, Vbat has no output. After…
Part Number: BQ24078 Hi,
I would like to learn what to expect from BQ24078 under these circumstances:
I have the charger up and running with IN at 5V and a battery charged to 3.8V, so that OUT is regulated to 3.8V + 210 mV. EN1=0 and EN2=1 so that ILIM…
Part Number: BQ24078 Hi, TI team
SYSOFF is internally pulled up to VBAT through a large resistor (approximately 5 MΩ).
But when I measured sysoff pin it is only 2.1V (battery voltage: 4.2V)
Is it correct value? Does It has divider internally?
Part Number: BQ24078 Hi,
I would like to check my understanding of BQ24078's output voltage regulation by the use of an example.
If I would charge/discharge my battery to 3.8V and then disable charging (CE high), would that make my OUT pin voltage…
