A6812EEPTR

Overview

The A6812EEPTR is a bipolar latch driver manufactured by Allegro MicroSystems, designed for power switching applications. It features a 1:20 input-to-output ratio with 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. It utilizes non-inverting parallel and serial interfaces for control. The component is housed in a 28-PLCC surface-mount package measuring 11.51x11.51mm. It functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides twenty independent high-side bipolar output channels controlled via a single input signal through a 1:20 decoding mechanism.
• Supports both parallel and serial interface protocols for flexible system integration and control logic compatibility.

Applications

• High-side power distribution systems requiring multiple switched loads
• Automotive lighting arrays and lamp drivers
• Industrial load management circuits

Procurement Notes

Verify the specific suffix EEPT against manufacturer documentation to confirm tape-and-reel packaging configuration. Confirm RoHS compliance status as official records indicate this part may not meet current environmental standards. Validate that the 28-PLCC footprint matches the target PCB design before procurement.

Selection Notes

Select this component when a high channel count is required from a single control line. Ensure the application requires high-side switching capability and can accommodate the 60V load voltage limit. Verify that the 28-PLCC package size fits the available board space constraints.

Part Context

This device belongs to the A6812 series of latch drivers from Allegro MicroSystems. These components are engineered for efficient multi-channel power management.
