BQ27542DRZR-G1 Sensor Chip Supplier
The BQ27542DRZR-G1 from Texas Instruments is a high-accuracy single-cell lithium-ion/lithium-polymer battery fuel gauge IC designed to monitor and report a battery’s state of charge (SoC) with precision and reliability in compact portable systems.
Built on Texas Instruments’ Impedance Track™ technology, the device continuously models the battery discharge characteristics to deliver accurate remaining capacity, runtime predictions, and voltage monitoring—even as the battery ages or operates under varying load and temperature conditions.
Housed in a small 12-pin SON (2.5 × 4 mm) package, the BQ27542DRZR-G1 is ideal for space-constrained designs. It communicates via I²C or HDQ interface, allowing easy integration with host microcontrollers without complex firmware requirements.
Key features
- Accurate state-of-charge (SoC) estimation for single-cell Li-ion batteries
- Impedance Track™ algorithm for long-term accuracy and battery aging compensation
- Supports battery capacity reporting, voltage, temperature, and runtime-to-empty prediction
- Low-power operation for battery-powered applications
- I²C / HDQ communication interfaces for simple system integration
- Designed for compact embedded battery monitoring applications
Typical applications
- Portable consumer electronics (phones, media players, cameras)
- Handheld industrial and medical devices
- Battery-powered IoT and embedded systems
- Embedded single-cell Li-ion battery packs
Overall, the BQ27542DRZR-G1 is used when a system needs reliable “fuel gauge” intelligence—turning raw battery behavior into usable runtime and charge information for the device and user.
