STC3100IQT — Overview
STC3100IQT by STMicroelectronics is a component in the Battery Monitor IC (single-cell Li-Ion coulomb counter / gas gauge) category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The STC3100IQT is a battery monitor IC from STMicroelectronics that measures the voltage, temperature and current of a single-cell Li-Ion battery and implements a Coulomb-counter gas gauge using a programmable 12- to 14-bit ADC. With a typical 30 mΩ sense resistor it supports battery currents up to 2.5 A and accumulates up to ±7000 mAh of capacity at 0.2 mAh resolution. Housed in a 3 x 3 mm DFN-8 package, it communicates over an I²C interface and includes an internal temperature sensor, a 32768 Hz time base, 32 bytes of RAM and an 8-byte unique ID, targeting cellular phones, PDAs, MP3 players, digital cameras and other portable devices.
