BQ76200PW

Battery Management Overview

The BQ76200PW is a high-voltage, high-side N-channel FET driver designed for battery pack protection. It supports 3 to 16 series cells with an operating supply voltage range of 8 V to 75 V and withstands up to 100 V absolute maximum. Packaged in a 16-TSSOP (4.40 mm wide) surface-mount format, it operates between -40°C and +85°C. The device draws 40 µA in normal mode and less than 10 µA in shutdown. It integrates charge/discharge drivers, a pre-charge PFET controller, and PACK+ voltage sensing.

Battery Management Feature Summary

• High-side NMOS FET drivers enable fast turn-on and turn-off times for battery protection applications.
• Integrated P-channel FET control allows low-current pre-charging of significantly depleted cell packs.
• Independent digital enable inputs provide separate control over charging and discharging paths.
• Scalable external capacitor-based charge pump accommodates various parallel FET configurations.

Battery Management Applications

• Electric bicycles, scooters, and motorcycles
• Energy storage systems and uninterruptible power supplies
• Lead-acid battery management

Battery Management Procurement Notes

Verify the package type matches the required 16-TSSOP form factor. Confirm the suffix 'PW' indicates tube packaging if specific handling is needed. Ensure compatibility with companion analog front ends like the bq76920/30/40 series. Check moisture sensitivity level requirements for assembly processes. Validate that the 100 V rating meets the system's peak voltage demands.

Battery Management Selection Notes

Select this component when high-side drive is required to prevent ground pin disconnection issues. It is suitable for systems needing independent charge and discharge control. Consider its low shutdown current for battery-powered applications. Ensure the host microcontroller can interface with the digital enable inputs. Verify support for the specific battery chemistry, such as lead-acid or lithium-ion.

Battery Management Part Context

The BQ76200 belongs to Texas Instruments' high-voltage battery protection family. It complements analog front-end monitors like the bq76920, bq76930, and bq76940. Designed for scalable battery packs, it simplifies design by integrating necessary drivers and controls. The PW variant specifically denotes the TSSOP package option within this product line.

Battery Management Replacement Considerations

Direct substitutes include other BQ76200 variants with different packages, such as BQ76200PWR. Cross-reference with bq769xx series combinations for complete protection solutions. Verify functional equivalence regarding voltage ratings and drive capabilities before substitution.
