[About chapter 8.3.1.2]
About the following description,
>An external resistor divider attenuates the adapter voltage before it goes to ACDET. If the battery boost mode is >not used, the adapter detect threshold must be programmed…
Part Number: BQ24800 Hi
For turning on the ACFET and RBFET, ACDRV voltage is 6V above CMSRC
CMSRC as the input should be generated first.
Whether the CMSRC is AC coupled @ adapter connecting in?
Whether the current is passing through C1, C2…
Part Number: BQ24800 About PROCHOT of IDCHG, is this compare between IDCHG pin signal(8 or 16 * (VSRN-VSRP) and REG 0x3DH[15:10]?
Or is this compare between sensed current consumption of RSR and REG 0x3DH[15:10]?
Could you teach which is correct?

Hi
According to the user’ s guide of BQ24800 EVM
2
The IC should be placed close to the switching MOSFET’s gate pins and keep the gate drive signal traces short for a clean MOSFET drive.
The IC can be placed on the other…
Part Number: BQ24800 About buck charging of BQ24800,
(1) Please teach the max duty (%) of buck charging.
We will use 4cell battery 17.6V max. We would like to know that the minimum input chargerging voltage to the battery(17.6V).
We think that…
Part Number: BQ24800 Hi team,
Customer wan to konw some questions as below;
1) PMON Gain Accuracy is described as Adapter Only and Battery Only, but in the case of Hybrid boost mode, what percentage should be expected?
2) REG0x38: spec page35 has…
Part Number: BQ24800 Hi team,
my customer set the both sensing resistor to 7m ohm because the input power is too larger to use 10m ohm normal setting.
since the charging register is based on 10m ohm, does this mean the current will times 10/7…
Part Number: BQ24800 Hi
According to 8.3.8.3, BQ24800 has CHG_OCP built in.
Could you please help to show how to identify this feature?
How to generate the additional current passing through 10m ohm current sensing resistor @ battery charging…
Part Number: BQ24800 We are thinking that we will use 2.2uH coil because we can use it from our stock. And charging current is around 6A and switching frequency 800kHz.
Is above combination no problem?
Or, we must be use 3.3uH as table 20? is changing…
