The ISL6295 is a low‑voltage fuel‑gauge IC that measures, stores, and reports critical rechargeable‑battery parameters such as charge/discharge current, voltage, and temperature. It integrates a 16‑bit sigma‑delta A/D converter, on‑chip voltage regulator, non‑volatile EEPROM, and an SMBus/I²C‑compatible 2‑wire communication interface.
Typical applications include notebook PCs, PDAs, and other handheld devices that use single‑cell Li‑ion/Li‑Polymer packs. The device is supplied in an 8‑lead TSSOP package and operates from –20 °C to +85 °C with very low supply currents in various power‑saving modes.
