Display Drivers Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm compliance with RoHS directives and REACH regulations. Ensure the ordering quantity aligns with the standard factory packaging of 2000 units or available cut tape options. Confirm that the SSOP-B40 package dimensions match the target PCB footprint requirements before finalizing procurement.

Display Drivers Selection Notes

Select this component when a 3-wire interface is required for space-constrained designs. It is appropriate for systems operating between 2.5 V and 5.5 V. Consider the 108-segment capacity and 700 mW power dissipation limits. Verify thermal management capabilities for the SSOP-B40 package if ambient temperatures approach the upper operational limit of 85°C.

Display Drivers Part Context

This part belongs to the BU9795 series of LCD drivers from ROHM Semiconductor. It shares the core architecture with variants like the BU9795BKV-E2 but differs in segment count and package type. The series is characterized by low standby current and compatibility with standard microcontroller interfaces for display control tasks.
