BQ24610RGER Présentation
A battery charge controller is a power management IC that regulates charging of rechargeable batteries, managing charge current, voltage regulation, preconditioning, and termination for safety and battery longevity. The BQ24610 belongs to the switched-mode charger family within the broader power management IC hierarchy, using a constant-frequency synchronous PWM controller to achieve far higher efficiency than linear chargers, which reduces heat dissipation in space-constrained designs.
Key features include a constant-frequency synchronous buck PWM controller with external MOSFETs for charge currents up to 10 A, high-accuracy regulation (0.5% charge voltage accuracy), adapter current regulation (input DPM), and charge status monitoring. Three-phase charging - preconditioning, constant current, and constant voltage - maximizes battery life. A system power selector allows the system load to run from the adapter or battery, while low quiescent current conserves battery energy during storage.
Technically, the BQ24610RGER implements a proprietary voltage regulated loop with programmable termination, safety timers, thermal regulation, and fault protection. Synchronous rectification reduces conduction losses; the controller architecture keeps external FETs off-package, allowing charge current to be scaled to the application needs. Stand-alone operation requires no host microcontroller for basic charging functions, simplifying system design.
Typical applications include notebook and tablet power banks, portable instruments, power tools, ePOS terminals, and medical devices requiring continuous system operation during charging (power path management).
Design tip: ensure proper PCB layout with thermal vias under the exposed pad, place the charge current sense resistor near the IC to reduce noise, and set the input DPM threshold to match the adapter rating to prevent adapter overload. Pricing shown reflects estimates as of 2026-08-29.

Applications typiques
BQ24610RGER convient pour 6 applications: Notebook and Tablet Power Banks, Portable Instruments and Test Equipment, Power Tools, ePOS Terminals and Retail Devices, Medical and Healthcare Devices, Lead-Acid Backup Power Systems.
Notebook and Tablet Power Banks
The BQ24610RGER suits notebook and tablet power-bank designs that require fast multi-cell charging from a DC adapter. Its synchronous buck controller with external MOSFETs scales charge current up to 10 A, cutting charge time versus linear chargers, while 0.5% charge voltage accuracy protects cell longevity. The integrated system power selector lets the system run from the adapter while the battery charges, and programmable input DPM prevents adapter overload. Typical implementations use a 2S-4S pack with 10-20 mOhm sense resistors for accurate current regulation.
Recommandé
Portable Instruments and Test Equipment
Portable test and measurement instruments benefit from the BQ24610RGER's stand-alone operation - no firmware or MCU code is needed to guarantee correct three-phase charging (precondition, CC, CV) with safety timers and fault protection. The power selector ensures the instrument stays operational from adapter power even with a deeply discharged pack. Low quiescent current minimizes battery drain in storage, and the 24-VQFN package integrates the analog control loop into compact handheld enclosures while external FETs handle the power stage.
Recommandé
Power Tools
Cordless power tools use 3S-6S Li-ion packs charged at high current; the BQ24610RGER's external-MOSFET synchronous buck topology supports charge currents up to 10 A with high efficiency, minimizing heat in the tool dock. Charge voltage accuracy of 0.5% and programmable termination protect high-drain cells from overcharge, while thermal regulation reduces charge current when the junction heats. Input DPM ensures the dock's AC adapter is not overloaded when both charger and motor controller draw current simultaneously during in-tool operation.
Recommandé
ePOS Terminals and Retail Devices
Electronic point-of-sale terminals need the display, printer, and compute platform alive during charging - exactly what the BQ24610RGER's system power selector provides. The controller routes adapter power to the system while independently regulating battery charge current, guaranteeing no brown-out during heavy thermal-printer current spikes. Programmable input DPM matches the adapter rating, and stand-alone termination frees the main MCU for transaction processing. Compact 4x4 mm VQFN packaging fits dense terminal PCBs with multiple buck regulators nearby.
Recommandé
Medical and Healthcare Devices
Portable medical devices such as patient monitors and infusion pumps require uninterrupted operation during charging; the BQ24610RGER's power path management guarantees the system never loses power when the battery is removed or deeply discharged. Stand-alone three-phase charging with safety timers provides deterministic, verifiable charge behavior useful for regulatory documentation. The synchronous architecture keeps efficiency high to limit internal heat rise in enclosed bedside equipment, and the 0.5% voltage regulation accuracy supports safe Li-ion cell operation over the pack lifetime.
Recommandé
Lead-Acid Backup Power Systems
The BQ24610RGER also charges lead-acid batteries used in UPS and backup-power nodes, leveraging its configurable voltage regulation loop and safety timers. The synchronous buck controller handles wide adapter inputs while the programmable regulation point matches 6V/12V lead-acid float or cycle profiles set by resistor dividers. Input DPM protects limited generator or adapter sources, and the system power selector lets the load run on adapter while the battery is topped up - a key requirement for alarm panels and gateway devices that must never power down.

Notes de conception
Solder the exposed thermal pad to a continuous ground pour with an array of thermal vias (8-12 vias, filled or capped) to conduct heat from the controller and anchor the thermal reference. Keep the synchronous buck power loop (input caps, high-side FET, inductor, low-side FET, PGND) as small as possible to limit switching-node ringing and EMI. Place sense resistors within 10-15 mm of the SRP/SRN and ACP/ACN pins with Kelvin routing per TI datasheet layout section.
Size the input DPM resistor divider so the ACSET threshold matches the adapter's continuous rating minus margin; if the adapter sags, the BQ24610 automatically reduces charge current to keep the system rail alive. Choose power MOSFETs with Rds(on) and gate charge optimized for the switching frequency - low Rds(on) at the cost of high Qg increases driver loss. Verify the bootstrap capacitor (typically 0.1 uF) is placed directly at BTST-PH.
Do not omit the NTC on the TS pin - without valid temperature feedback the charger will fault or charge outside the safe window; program the divider for the cell vendor's specified charge/terminate temperatures. Ensure the charge voltage VREG divider tolerance is 0.1-1% since regulation accuracy is 0.5% only with precision dividers. Note that some parameters such as exact input voltage range should be confirmed against the latest TI datasheet revision.
