Frequently Asked Questions
What type of IC is the STC3100IQT and what does it measure?
The STC3100IQT is a battery gas gauge (fuel gauge) IC from STMicroelectronics. It measures battery current (via coulomb counting), terminal voltage, and temperature to provide an accurate state-of-charge (SoC) estimate to the host system, enabling intelligent battery management and runtime prediction in portable devices.
What communication interface does the STC3100IQT use?
The STC3100IQT uses an I2C-compatible serial interface for communication with the host microcontroller or application processor. This industry-standard two-wire interface simplifies integration, requiring only SDA and SCL connections, and is supported natively by virtually all modern embedded processors and SoCs.
What package is the STC3100IQT available in and what are its dimensions?
The STC3100IQT is supplied in a DFN-8 (Dual Flat No-Lead, 8-pin) plastic package measuring 3x3 mm with a 0.5 mm pin pitch and 1 mm body height. This ultra-compact footprint, combined with the no-lead exposed pad design, minimizes PCB area usage and is well-suited for high-density layouts in portable consumer and industrial electronics.
Is the STC3100IQT RoHS compliant?
Yes, the STC3100IQT is RoHS compliant, carrying a JESD-609 code of e3 (Pb-free). The plastic DFN-8 package is manufactured without lead or other regulated hazardous substances, making it suitable for use in consumer electronics, medical devices, and other environmentally regulated end products across global markets.
What battery chemistries and applications is the STC3100IQT designed for?
The STC3100IQT is optimized for single-cell Li-ion and Li-polymer rechargeable batteries, which are the dominant chemistry in portable electronics. It is used in smartphones, tablets, portable medical monitors, handheld test instruments, wearable devices, and IoT nodes — any application requiring accurate battery state-of-charge reporting and low-power operation.
