Typical Applications
BQ7695202PFBR is suitable for 6 applications: E-Bike and Light Electric Vehicle Battery Packs, Power Tool Battery Packs, UPS and Energy Storage Modules, Robotics and Drone Battery Packs, Portable Instrumentation and Medical Devices, Industrial IoT and Smart Battery Systems.
E-Bike and Light Electric Vehicle Battery Packs
The BQ7695202PFBR fits 13S and 16S Li-ion packs typical of 36V-60V e-bike and scooter systems, where its 3S-16S range and high-accuracy cell monitoring enable precise state-of-charge estimation across the pack. Integrated high-side charge-pump NFET drivers directly drive the charge and discharge protection FETs, removing external driver stages and shrinking BMS board area. Autonomous overcharge, over-discharge, overcurrent, and short-circuit protection continues even if the host MCU link via I2C, SPI, or HDQ is lost, a key safety property for rider-facing packs. The dual programmable LDOs can power the vehicle's display or telemetry MCU from the pack directly, and integrated cell balancing preserves long-term capacity in packs subjected to deep daily cycling.

Power Tool Battery Packs
Professional power-tool packs in the 4S-10S Li-ion range benefit from the BQ7695202PFBR's autonomous protection state machine, which reacts to overcurrent and short-circuit events faster than any software loop running on a shared MCU. The high-accuracy cell voltage measurement supports fuel-gauging algorithms that avoid the sudden shutdowns users experience with poorly estimated packs. Because the device integrates charge-pump high-side NFET drivers, a compact trigger-side BMS can be realized with a single monitor IC and external FETs. Its -40C to +85C operating range covers packs stored in cold vehicles or exposed to job-site heat, and the 48-pin 7x7 mm TQFP fits the cylindrical cell arrangement of typical pack form factors with a single-layer cell-sensing bus.

UPS and Energy Storage Modules
Server-rack UPS and modular energy-storage units commonly use 15S-16S Li-ion or LiFePO4 strings, exactly at the top of the BQ7695202PFBR's 3S-16S range. The high-accuracy monitor reduces measurement guard bands, allowing fuller utilization of installed capacity - a direct cost saving per kWh. The dual programmable LDOs can bias isolation or communication circuitry, and the 400-kHz I2C or SPI host link feeds pack data to a system supervisor. For LiFePO4 chemistry, whose flat discharge curve makes voltage-based estimation demanding, the device's measurement accuracy directly improves state-of-charge fidelity. Integrated balancing keeps series strings matched over thousands of float-and-cycle operations typical of standby applications.
Recommended
Robotics and Drone Battery Packs
Autonomous mobile robots and industrial drones fly or roll on 6S-12S Li-ion and Li-polymer packs, squarely inside the BQ7695202PFBR's supported range. Fast discharge pulses demand robust short-circuit and overcurrent protection, which the integrated protector delivers autonomously with high-side FET control, independent of the flight or motor controller. High-accuracy per-cell monitoring feeds state-of-charge estimation that mission planners rely on to guarantee return-to-home margins. The SPI host interface supports the fast polling rates typical of robotic main controllers, while HDQ one-wire offers a minimal-pin option for telemetry sub-systems. The -40C to +85C range covers unheated airframes and cold-soak ground operations.
Recommended
Portable Instrumentation and Medical Devices
Battery-powered test instruments and portable medical devices use 3S-6S Li-ion packs where runtime predictability and safe fault behavior are critical. The BQ7695202PFBR's high-accuracy cell measurement supports the conservative, auditable state-of-charge reporting expected in medical and laboratory environments, and its autonomous protection provides a hardware-level safety layer independent of the application firmware, simplifying risk analyses. Low-count packs benefit from the integrated LDOs, which can power gauge or display electronics without a second regulator IC. The compact 48-pin 7x7 mm TQFP suits handheld enclosures, and I2C communication integrates cleanly with low-power microcontrollers commonly used in battery-operated instruments.
Recommended
Industrial IoT and Smart Battery Systems
Smart battery packs for industrial IoT gateways, sensors nodes, and backup modules require remote telemetry: the BQ7695202PFBR provides per-cell voltages, balancing status, and protection flags over 400-kHz I2C to a gateway MCU, enabling predictive maintenance based on cell health trends. Its HDQ one-wire interface allows integration into legacy single-wire battery buses, and SPI supports high-speed logging applications. Integrated cell balancing extends calendar life in packs that sit at float for long periods, and the autonomous protector guarantees safe behavior during communication outages or firmware faults. The dual programmable LDOs can power the IoT radio module from the pack, reducing external component count in sealed smart-battery assemblies.

Key Differentiators
- 16S cell-count ceiling in a single monitor IC (vs BQ76952PFBR (family base option))
- Integrated high-side charge-pump NFET drivers (vs Lower-cell-count TI devices such as BQ76942 (not drop-in))
- Dual programmable LDOs for system power (vs BQ7695201PFBR / BQ76952PFBR)
Design Notes
Cell voltage accuracy depends directly on sensing layout. Route cell-tap sense lines differentially from each cell junction to the VCx pins, and place a small RC filter (as specified in the TI datasheet typical application) near the IC to reject pack noise. Avoid routing sense lines parallel to FET switching paths; high dV/dt on the discharge FET drains couples into high-impedance sense inputs and degrades the high-accuracy measurement the BQ76952 family is chosen for. Follow the TI EVM (BQ76952EVM evaluation module) layout as a proven reference.
The integrated charge-pump high-side NFET drivers eliminate external driver ICs, but FET selection must respect gate-drive capability: verify each FET's total gate charge and threshold against the datasheet drive specifications for your FET count per path. Paralleling FETs increases total gate charge and slows switching; confirm the charge pump supports your configuration. Size the protection FETs RDS(on) so conduction loss at continuous rated pack current keeps FET junction temperatures within rating under your worst ambient.
The BQ76952 suffix (00/01/02) encodes feature-option differences within the family. Ordering the wrong suffix can mean firmware expecting a specific interface or feature set finds it absent, even though the package and pinout are identical. Before BOM freeze, cross-check the ordering-option table in the TI datasheet against every register/peripheral your firmware uses. Also confirm host-side pull-up and voltage-level compatibility for I2C, SPI, or HDQ against the datasheet logic levels.
