BU9795ZKS2-E2

Display Drivers Overview

The BU9795ZKS2-E2 is an LCD driver manufactured by ROHM Semiconductor, designed for segment displays with a capacity of up to 140 segments. It operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 104 Hz. The device features a 3-wire interface and is housed in a reel package suitable for surface mount technology. It has a maximum power dissipation of 850 mW and functions reliably across an operating temperature range from -40°C to +85°C.

Display Drivers Feature Summary

• Supports driving up to 140 LCD segments via a 3-wire serial interface
• Operates on a low voltage supply ranging from 2.5 V to 5.5 V
• Designed for surface mount installation in compact electronic assemblies

Display Drivers Applications

• Segment LCD display modules
• Low duty cycle LCD drivers
• Consumer electronics requiring simple serial control interfaces

Display Drivers Procurement Notes

Verify the specific suffix E2 indicates reel packaging when sourcing this component. Confirm that the NRND status does not impact immediate project requirements. Ensure compatibility with existing PCB footprints and reflow profiles. Check for moisture sensitivity labeling prior to storage. Validate that the 140-segment capacity meets the target display specifications.

Display Drivers Selection Notes

Select this component for designs requiring a dedicated LCD driver with minimal pin count due to the 3-wire interface. Consider the 2.5 V to 5.5 V operating range for battery-powered or low-voltage systems. Evaluate the 140-segment limit against display complexity. The SMD format suits automated assembly processes. Verify thermal management capabilities given the 850 mW power dissipation rating.

Display Drivers Part Context

This part belongs to the BU9795 series of LCD drivers from ROHM Semiconductor. It is specifically the tape-and-reel variant (E2 suffix) of the BU9795ZKS2. The series focuses on low-duty LCD segment driving applications. It shares core electrical characteristics with other variants in the family but differs in packaging and handling specifications.

Display Drivers Replacement Considerations

BU9795ZKS2 is the tray-packaged equivalent of this component. Both share identical electrical specifications and functionality. The primary difference lies in the shipping packaging format. Designers may substitute one for the other if packaging constraints allow.
