  • BQ24401: Ni-MH battery

    TI Thinks Resolved
    Part Number: BQ24401 Hi, I have been looking for 1~4 AA size Ni-MH charging IC. I have chosen for BQ24401 for my appliication. Max current capacity of the battery: 2500mAh Max voltage of the battery: 4.8V( 4 batteries connected in series) 1…

  • RE: BQ24401: Selection of battery charging IC-Ni-Mh

    Hi Shruti, BQ24401 is the dedicated NiMH battery charger with the termination approaches of temperature rise rate and maxim in the limited NiMH battery charger portfolios. Alternatively, there is an application note using BQ24105 or BQ24105-Q1and a…

  • RE: BQ24401: single cell NiMh charging from 5V USB

    Would you increase the input voltage to 7V or higher to see the EVM work or not?

  • BQ24401-NiMH charger

    Other Parts Discussed in Thread: BQ24401 Hi, we have quite old devices for NiMH battery chargers and without EVMs. Is there a way to use a LiIon switching charger and to adapt for example to a 2s NiMH configuration? About the BQ24401, we have 2V…

  • BQ24401 - Max charging Voltage Clarifications

    Other Parts Discussed in Thread: BQ24401 Hello, I use the BQ24401 (programmable NiCd/NiMH Fast-Charge Management IC) to recharge a single NiMH battery type that has a nominal voltage of 1.2 V. The VMCV value (Maximum cell voltage) is fixed (2 Volt)…

  • RE: BQ2002T and BQ24401 Operation Topology

    bq2002T and bq24401 doesn't have power path control. You have to add the extra power path control circuit to directly supply to the system load and the battery will start discharge when there’s no VCC supply to the ICs or other power path control.

  • RE: NiMH 3S2P System - Using bq34Z100-G1 with bq24401

    The bq34z100-G1 should work with the bq24401 charger. They do not communicate with one another, but the gauge should detect charge termination after the delta criteria have been met. You can still use the bq2014H device, although applications support…

  • bq24401 / Peak pulse current at Top-Off and Pulse-Trickle Maintenance Charge

    Resolved
    Hi, I understand that the pulse current is delivered to the battery during both Top-Off and Pulse-Trickle Maintenance Charge. But I can't find the description of which peak current will be delivered at this pulse current. Is it the same current level…

  • BQ24401 - low PWM frequency - no dT/dt-detection - input current regulation instead of output regulation - corresponding current regulation is sensitive to input impedance

    Resolved
    Other Parts Discussed in Thread: BQ24401 I have a serious problem with the BQ24401 1. low PWM frequency From 12 identically assembled prototypes only 1 reaches the 300 kHz PWM frequency, 2 have abt 130 kHz and the rest are below 60 kHz. The components…
