Part Number: BQ24074 Other Parts Discussed in Thread: BQ27Z561-R2 , , BQ28Z610 Dear Team
The customer accord the battery spec and design the charge current, then they may expect the time of battery full charge.
And they use Pin 14 (TMR) to set an…
Part Number: BQ24074 In BQ24074 battery charger, we have some doubts:
1. When battery is present and input is connected, what will be charger output?
2. When battery is absent and input is connected, what will be charger output?

Part Number: BQ24074 Hi,
I would like the know what the on-resistance of the power path transistor Q2 is. Furthermore, what is the maximum continuous current the device can deliver when only Q2 is on, i.e. when the voltage at the IN-port is 0 ?
Thanks…
Part Number: BQ24074 Other Parts Discussed in Thread: BQ24075 , BQ24079 We are working on a 4G automotive GPS tracker where the peak power requirement would be 12W (4V @2A & 3.3 @1A).
The system will have one integrated Li-ion cell. We like to use BQ…
Part Number: BQ24074 Customers now use bq24074 to produce rechargeable products. The battery charged is 5000mAh. The customer found that some batteries will not be recharged from 3.0V to 3.8V. At this time, the output of CHG (pin9) keeps jumping (output…
Part Number: BQ24074 Hello Team,
We are use BQ24074 in our VTS project. Problem was after giving input supply to circuit the our device was restart after some time if battery was not connected. If we connect battery device was working fine. Please find…

Hello
I am planning on measuring the voltage on the ISET pin with an Arduino to get the charge current. Are there any special requirements on the ADC input impedance, so that it won't affect the charger when measuring that voltage…
Part Number: BQ24074 Dear TI,
In a close reading of the datasheet for part BQ24074, it is not obvious to me what the state of the chip is when the power IN is disconnected and the battery voltage is also below 3V (Vlowv), so I am unsure if I need an…
Part Number: BQ24074 Hi,
In bq2407x datasheet is mentioned that there is reverse current protection, but there isn't more information about this. This protection is only to prevent battery to be connected to Vin when VBAT>VIN?
In a situation where…
