This document is the datasheet for DS2792, which introduces the functions and features of the product and its application scenarios
The DS2792 is a programmable fuel‑gauge IC that integrates a 16‑bit MAXQ20 microcontroller, EEPROM, RAM, and analog measurement peripherals for Li‑ion and NiMH battery packs. It provides current, voltage, and temperature monitoring and communicates via a 19.2 kbps UART interface.
Key features include a supply voltage range of 2.5 V‑10 V, low‑power operation (CPU mode 1.5 mA, sleep mode ~25 µA), 4 k‑word EEPROM program memory, 64 words data EEPROM, and a 28‑pin TDFN package. The device supports JTAG debugging and offers extensive pin‑out and electrical specifications for designers.
