BM1Z002FJ-E2

Overview

The BM1Z002FJ-E2 is an AC voltage zero-cross detection IC designed for household appliances. It operates within a supply voltage range of 10 V to 28 V and consumes a typical operating current of 160 uA. The device features a variable output waveform and supports a maximum switching frequency of 0.065 kHz. It includes thermal shutdown and under-voltage lockout protections, functioning reliably between -40°C and +105°C in a SOP-J7S package.

Feature Summary

• Eliminates the need for photocouplers and external components to reduce part count
• Provides modifiable zero-cross delay timing for flexible control
• Features open-drain output with VCC under-voltage lockout protection

Applications

• Household appliances
• Non-isolated AC voltage detection systems
• Isolated AC voltage detection systems

Procurement Notes

Verify the specific suffix E2 against official ROHM documentation to confirm pinout and electrical characteristics. Ensure the SOP-J7S package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing procurement.

Selection Notes

Select this component when designing power supplies that require precise zero-crossing detection without using optocouplers. It is suitable for applications demanding reduced standby power consumption and simplified circuit topology compared to traditional isolation methods.

Part Context

This part belongs to ROHM's specialized PMIC line focused on AC voltage detection. It replaces conventional optocoupler-based solutions, offering a compact alternative for detecting AC mains zero-cross points in residential electronics while maintaining high reliability.

Replacement Considerations

BM1Z012FJ-E2 and BM1Z001FJ-E2 are related zero-cross detection ICs from the same manufacturer. Verify functional compatibility and pin assignments before substituting these parts in existing designs.
