A6812EEP-T

Overview

The A6812EEP-T is a discontinued power driver IC manufactured by Allegro MicroSystems. It functions as a bipolar latch driver with a 1:20 input-to-output ratio, providing twenty high-side outputs. The device operates on a supply voltage range of 3V to 5.5V and supports a maximum load voltage of 60V. Each output channel delivers a maximum current of 40mA. It utilizes parallel and serial interfaces for control and is housed in a 28-PLCC surface-mount package measuring 11.51x11.51mm. The component is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides twenty independent high-side bipolar outputs controlled via a single input signal through a 1:20 ratio architecture.
• Integrates a latch driver mechanism to maintain output states without continuous input signaling.
• Supports both parallel and serial interface protocols for flexible system integration.

Applications

• Vacuum fluorescent display drivers
• High-side load switching applications
• Bipolar power distribution systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required, though official documentation primarily lists the 'A6812EEP' variant. Confirm RoHS compliance status as the standard part is noted as non-compliant. Check for obsolescence notices from Allegro MicroSystems regarding this specific series before finalizing procurement plans.

Selection Notes

Select this component when a high-channel count bipolar driver is needed for vacuum fluorescent displays or similar loads. Ensure the system requires a 60V load rating and 40mA per channel capability. Verify that the 28-PLCC package dimensions fit the PCB layout constraints and that the 3V to 5.5V supply voltage aligns with the design specifications.

Part Context

This part belongs to the A6812 family of power drivers designed for high-density output applications. It is distinct from lower-channel variants like the A6801 and higher-channel models such as the A6818. The EEPROM designation typically implies internal configuration storage capabilities within the broader product line context.

Replacement Considerations

Public confirmed substitute part numbers include MAX6921AQI+ and MAX6921AQI+T from Analog Devices Inc./Maxim Integrated.
