BQ24610QRGERQ1 Visão geral
A battery charge controller is a power management IC that regulates current and voltage delivered to rechargeable cells. The BQ24610 manages the full charge profile: preconditioning (trickle charge for deeply discharged cells), constant-current (CC) fast charge, constant-voltage (CV) regulation, and charge termination, with automatic recharge when the battery voltage falls below the recharge threshold.
Key features include a constant-frequency current-mode PWM controller with high-accuracy charge current and voltage regulation (0.5% charge voltage accuracy), an integrated system power selector (NVDC-style power path) that allows the system to boot from the adapter even with a deeply discharged or absent battery, adapter current regulation to prevent adapter overload, and low quiescent current for efficiency. Charge status outputs and safety timers provide monitoring and fault protection including thermal shutdown and battery temperature qualification via TS pin (JEITA-style NTC monitoring).
The controller architecture keeps power losses in external components, enabling charge currents of several amperes set by the external sense resistor, with programmable switching frequency for inductor and MOSFET optimization. Input voltage operating range supports common automotive and adapter rails up to 28 V.
Typical applications include automotive infotainment and telematics backup batteries, portable industrial instruments, medical handheld devices, and 1-6 cell battery-powered systems requiring power-path management. For a non-automotive equivalent, the BQ24610RGER shares the same die and footprint.
Design tip: size the sense resistor for the target fast-charge current (Rsense = 50 mV / Ichg typical), and follow the TI datasheet layout guidelines to place the bootstrap capacitor, gate-drive loops, and NTC network close to the IC for robust synchronous buck operation.

Aplicações típicas
BQ24610QRGERQ1 é adequado para 6 aplicaçãos: Automotive Telematics Backup Battery, Portable Industrial Instruments, Medical Handheld and Portable Devices, Industrial Battery-Powered Data Loggers, Multi-Cell Speaker and Audio Systems, Robotics and AGV Auxiliary Battery Charging.
Automotive Telematics Backup Battery
The BQ24610QRGERQ1 charges 1-2 cell Li-ion backup batteries that keep telematics and eCall modules alive during cranking transients and key-off conditions. Its AEC-Q100 qualification and up to 28 V input tolerance handle automotive 12 V rail excursions, while the system power selector lets the telematics ECU boot directly from the vehicle rail even if the backup cell is deeply discharged. The TS pin NTC monitoring prevents charging outside safe battery temperatures in cabin environments.
Recomendado
Portable Industrial Instruments
Handheld test and measurement instruments using 2-4S Li-ion packs benefit from the BQ24610QRGERQ1's high-accuracy CC/CV regulation (0.5% class charge voltage accuracy) and programmable fast-charge current via the external sense resistor. The synchronous buck topology with external MOSFETs achieves high efficiency at multi-amp charge rates, minimizing heat in sealed enclosures, and the STAT1/STAT2 outputs drive simple LED status indication for operators.
Recomendado
Medical Handheld and Portable Devices
Portable medical diagnostics require reliable, safe battery charging with termination and safety timers. The BQ24610QRGERQ1 provides preconditioning for over-discharged packs, NTC-based battery temperature qualification, and programmable charge termination, protecting patient-adjacent devices. Its low quiescent current extends standby runtime, and the power selector guarantees the device powers up on adapter insertion even with an absent battery - important for clinical uptime.
Recomendado
Industrial Battery-Powered Data Loggers
Field data loggers with 1-3S Li-ion packs charge from 12-24 V industrial adapters. The BQ24610QRGERQ1's wide input range and adapter current regulation prevent overloading shared supply rails, while charge status outputs interface to a host MCU for fleet monitoring. The automotive qualification margin also suits harsh factory floor temperature and vibration conditions beyond typical consumer charger ICs.
Recomendado
Multi-Cell Speaker and Audio Systems
Portable PA and premium Bluetooth speakers using 3-4S packs need several amps of charge current to shorten recharge time. Because the BQ24610QRGERQ1 drives external MOSFETs, designers scale the sense resistor and power stage to 5 A or more while the constant-frequency current-mode control keeps loop behavior predictable. Adapter current limiting lets the speaker run at full playback power while charging without tripping the external supply.
Recomendado
Robotics and AGV Auxiliary Battery Charging
Autonomous mobile robots and AGVs use 4-6S packs for onboard controllers. The BQ24610QRGERQ1 supports up to 6-cell charging with a synchronous buck power stage scaled for high current, plus a power selector that lets the robot's compute stack boot from docking power before the pack is connected. Thermal shutdown and safety timers protect packs charged in confined, thermally stressed enclosures.

Notas de projeto
Set fast-charge current with the SRP-SRN sense resistor using the datasheet equation; 10 mΩ to 20 mΩ values are typical for 2.5-5 A designs. Power dissipation is dominated by external high-side/low-side MOSFET Rds(on) and switching loss - select FETs with low Qg and Rds(on) and verify thermal rise at worst-case VIN and charge current. Ensure adapter detection divider on ACDET matches the adapter voltage window.
Follow TI datasheet PCB layout guidelines: keep the BTST bootstrap capacitor close to BTST and PH, minimize the gate-drive loop area, route SRP/SRN as Kelvin connections directly at the sense resistor pads, and use a solid PGND plane under the power stage. Place the TS resistor divider near the battery pack NTC connector with filtering to reject noise.
Do not omit the VREF output capacitor or exceed the ACDET absolute maximum rating during automotive load-dump events - add front-end TVS protection on the adapter input. Verify the safety timer setting matches the pack capacity so slow trickle charging of a deeply discharged battery is not terminated prematurely. Stat pins are open-drain style outputs; include pull-up resistors sized for LED or MCU input loading.
