BD7694FJ-E2

Overview

The BD7694FJ-E2 is a Power Factor Correction (PFC) controller IC manufactured by ROHM Semiconductor. It operates within a supply voltage range of 10V to 38V and supports an operating temperature range from -40°C to +105°C. The device is housed in an 8-SOP-J surface-mount package, specifically an 8-SOIC with a width of 3.90mm. It features critical mode control for PFC applications and includes integrated brown-out detection functionality.

Feature Summary

• Integrates critical mode control architecture for power factor correction
• Includes built-in brown-out detection function for system protection

Applications

• Power factor correction systems requiring improved power quality
• Electronic devices needing brown-out protection during voltage dips

Procurement Notes

Verify the specific suffix E2 against official ROHM documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the SOP-J-8 footprint aligns with your PCB layout guidelines. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement.

Selection Notes

Select this component when a compact PFC solution with integrated brown-out protection is required. The wide operating temperature range suits industrial or automotive environments. Verify that the 10V to 38V supply range matches your system's available rail voltages.

Part Context

This part belongs to ROHM's Power Factor Correction IC family. It complements other controllers like the BD7695FJ-E2 by offering specific brown-out features. It is designed for efficient power management in consumer and industrial electronics where space and reliability are critical constraints.

Replacement Considerations

Check ROHM's official substitution guide for direct replacements. The BD7695FJ-E2 is a related PFC controller but may lack the specific brown-out integration. Verify pin compatibility and electrical parameters before substituting.
