A6812EEP

Overview

The A6812EEP is a power driver IC manufactured by Allegro MicroSystems, designed for bipolar load switching applications. It features a 1:20 input-to-output ratio with twenty high-side outputs capable of delivering up to 40mA each. The device operates on a supply voltage between 3V and 5.5V and supports loads up to 60V. It utilizes parallel and serial interfaces for control. Packaged in a 28-PLCC (11.51x11.51) surface-mount housing, it functions within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Provides twenty independent high-side bipolar output channels for load driving
• Supports latch driver functionality for maintaining output states
• Enables control via both parallel and serial interface protocols

Applications

• Automotive lighting systems requiring high-side switching
• Industrial load distribution networks
• Bipolar motor or solenoid driver circuits

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance as the part does not meet current standards. Validate pin compatibility with existing PCB layouts before integration. Check for available alternatives from Analog Devices if new production is required.

Selection Notes

Select this component for designs requiring multiple high-side outputs controlled by minimal inputs. Ensure the system voltage aligns with the 3V to 5.5V operating range. Consider the 28-PLCC package constraints during thermal management planning. Verify that the 40mA per channel limit meets the specific load requirements.

Part Context

This integrated circuit belongs to the A6812 series of power drivers from Allegro MicroSystems. It is specifically engineered for applications needing efficient control of numerous bipolar loads. The device simplifies circuit design by integrating multiple driver channels into a single compact package.
