Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: BQ2004 Hello team,
Could you please help me to answer customer questions below?
The charging current is determined by the resistor RSNS between SNS pin and GND, correct?
The allowed RSNS power is calculated from IREG^2 * RSNS. When fast-charge…
Part Number: BQ2004 Hello,
To best of my knowledge switch-activated discharge-before charge allows bq2004-based chargers to support battery conditioning and capacity determination. However, I can't see in the datasheet how discharge voltage threshold…
Part Number: BQ2004 Hello TI Support team,
I'm using BQ2004 charger for my project to charge 12-cell NiMH battery block. I'm required to use discharge feature that discharges battery before recharge.
I'm studying Discharge-Before-Charge feature…
Part Number: BQ2004 Is there a limit to the input order of VIN and VCC of bq2004?
Normally it is VIN-->LDO (DCDC --> VCC this time). If batteries are present, I think the VCC will be powered first.
I attached block diagram. Could you please check…
Part Number: BQ2004 The thermistor to be set in BQ2004 is planned to be 103KAT-4/SEMIETC. The heat dissipation and heat time constants are different from the 103AT-2/SEMIETC described in DV2004L1, what values should be set for RT1 and RT2?
Best regards…
Part Number: BQ2004 I try to charge a two or three cell NIMH Akku using a BQ2004H.
Charging stops always after 23 minutes.
Can You give me a Hint what i am doing wrong?
Regards Fabian
Here is the configuration:
VCC 5V stabilized
DCMD VCC
DSEL VCC
VSEl…
Part Number: BQ34Z100-G1 Other Parts Discussed in Thread: BQ2004 , , BQ34Z100
Hello,
We have a design using a BQ2004 as battery charger. We use a sensing resistor to control the current in our battery pack.
Can we use a BQ34Z100-G1 as Battery Gas Gauge…
Part Number: BQ2004 Hello,
I have two questions about the termination condition of the BQ2004, we are using it with a 4x AA VH 1900 cell battery pack.
Is it possible to use the Delta T/ Delta t and the maximum voltage termination conditions at the same…
Part Number: BQ2004 Hello,
I have two questions about Delta T/ Delta t the termination condition of the BQ2004, we are using it with a 4x AA VH 1900 cell battery pack, with a NTC, reference 103AT-2 from Semitec.
By default, to how many C°/min correspond…
Part Number: BQ2004 Other Parts Discussed in Thread: BQ24725A , BQ24610 , BQ24170 Hi E2E support team,
Our customer request 4 cells 1520mAh NiMH pack(4S1P: 1.2Vx4 = 4.8V) with trickle charging supported. Please advise how to config BQ2004 with default trickle…
