BQ76200PWR Description

The BQ76200PWR is a high-voltage battery pack front-end charge/discharge high-side NFET driver. High-side protection avoids ground disconnection in the system and also allows continuous communication between the battery pack and the host system. The BQ76200PWR driver has additional P-Channel FET control to allow low-current pre-charge to a deeply depleted battery, and a PACK+ voltage monitor control for the host to sense the PACK+ voltage. Because of the distinct enable inputs, CHG and DSG FETs can be turned on and off independently, providing tremendous implementation flexibility in battery systems.

BQ76200PWR Features

• CHG and DSG high-side NMOS FET drivers for battery protection and fast FET turn-on and turn-off times

• Pre-charge PFET driver (for current-limited precharge of significantly depleted cell pack)

• Independent digital enables control for charging and discharging

• Minimal external components needed

• High-voltage tolerant (100-V absolute maximum)

BQ76200PWR Applications

• Portable medical systems

• eBikes, eScooters, and motorcycles

• 12-V to 48-V battery packs

• Energy storage systems and uninterruptible power supplies (UPS)

• Lead-acid (PbA) replacement batteries

• Wireless base-station battery systems
