BQ2202SN

Overview

The BQ2202SN is a nonvolatile SRAM memory controller IC manufactured by Benchmarq. It operates within a supply voltage range of 4.5V to 5.5V and is housed in a 16-SOIC package with a width of 3.90mm. The component supports an operating temperature range from -40°C to 85°C. This integrated circuit is designed to manage nonvolatile static random-access memory functions, providing essential control signals for data retention and system integrity in electronic applications.

Feature Summary

• Nonvolatile SRAM memory controller functionality
• Compact 16-SOIC surface-mount package design
• Wide industrial operating temperature capability

Applications

• Industrial systems requiring reliable memory control
• Consumer electronics utilizing nonvolatile storage
• Digital systems needing low-power reset management

Procurement Notes

Verify the specific suffix (e.g., SN vs. SN-N) against official Benchmarq documentation to confirm exact electrical characteristics and pinout compatibility. Ensure the source provides valid datasheets confirming the 4.5V-5.5V supply range and SOIC package dimensions. Cross-reference manufacturer part numbers to avoid confusion with similar PMIC or battery charger variants that may share naming conventions.

Selection Notes

Select this component when a dedicated nonvolatile SRAM controller is required for systems operating between 4.5V and 5.5V. Consider the 16-SOIC footprint for PCB layout constraints. Verify thermal requirements against the -40°C to 85°C operating range. Confirm interface compatibility with the target memory devices before integration into the final design.

Part Context

Benchmarq specializes in power management and support circuits. The BQ2202SN falls under the memory controllers category, distinct from their battery charging products. It serves as a support circuit ensuring data integrity in nonvolatile memory applications, complementing broader system power architectures.

Replacement Considerations

Check for direct cross-references from Microchip or other distributors. Verify pin-to-pin compatibility and electrical specifications before substituting.
