BQ2204ASN TI SRAM Nonvolatile Controller | 16-SOIC | 4.5V-5.5V, 3.0V-3.6V

Product Overview

The BQ2204ASN from Texas Instruments is a nonvolatile SRAM controller designed to provide battery backup and power-fail protection for standard CMOS SRAMs. It integrates a precision voltage reference, power-fail comparator, and battery switchover circuitry in a compact 16-SOIC package. The device ensures data retention during power loss by automatically switching to a backup battery when the primary supply drops below a threshold. It supports both 5V and 3.3V SRAMs, making it versatile for various applications requiring reliable data storage.
