BQ29412PWG4 Description

Short technical summary and product information.

The Texas Instruments BQ29412PWG4 is a secondary overvoltage protection IC designed for 2, 3, or 4-cell lithium-ion battery packs. It incorporates a high-accuracy precision overvoltage detection circuit with a fixed threshold of 4.45V. This device is suitable for applications requiring robust battery protection, such as in notebook computers, portable instrumentation, and other portable equipment.

 

The bq2941x series, including the bq29412, features low power consumption with ICC typically less than 2 µA. The IC begins a protection sequence when one cell reaches an overvoltage condition. It charges an external capacitor through the CD pin, and when the CD pin voltage reaches 1.2V, the OUT pin changes state.

 

This IC is available in an 8-TSSOP package, designed for surface mounting. It operates within a temperature range of -40°C to 110°C (TA), making it suitable for a wide variety of environmental conditions. The device provides essential protection for Li-Ion battery packs, contributing to safety and longevity.

 

Note: The datasheet associated with this part (BQ29414DCTR) may not be specific to the BQ29412PWG4. It is recommended to verify all specifications with the correct datasheet for the BQ29412PWG4.
