A6833SEPTR-T

Overview

The A6833SEPTR-T is a bipolar latch driver manufactured by Allegro MicroSystems, designed for power switching and load driving applications. It features a 1:32 input-to-output ratio with 32 low-side outputs. The device supports both parallel and serial interfaces and operates within a supply voltage range of 3V to 5.5V. It delivers a maximum output current of 125mA per channel and withstands load voltages up to 30V. Packaged in a 44-PLCC (J-Lead) surface-mount format measuring 16.59x16.59mm, it functions reliably across an operating temperature range of -20°C to +85°C.

Feature Summary

• Integrates a 1:32 decoding architecture to manage thirty-two independent bipolar output channels from a single control signal.
• Supports flexible system integration through selectable parallel and serial interface modes for input control.
• Provides robust power handling capabilities with high current drive capacity and significant load voltage tolerance.

Applications

• Bipolar stepper motor control systems
• High-density LED matrix displays
• Relay bank switching circuits

Procurement Notes

Verify component authenticity through official Allegro MicroSystems channels or authorized distributors. Confirm the specific suffix 'SEPTR-T' matches the required 44-PLCC package and tape-and-reel configuration. Check for recent Product Change Notices regarding packaging updates. Ensure compliance with RoHS3 standards and MSL level 3 handling requirements during storage and assembly processes.

Selection Notes

Select this component when a high channel count is required within a compact footprint. The 1:32 ratio reduces microcontroller pin usage compared to direct drive solutions. Consider the 30V load limit and 125mA output current against specific load requirements. Evaluate the trade-off between serial/parallel interface complexity and board space savings offered by the 44-pin PLCC package.

Part Context

This part belongs to the A6833 series of bipolar latch drivers. It shares functional similarities with the A6832 but differs in maximum load voltage specifications. The device is categorized under PMIC load drivers and serves as a bridge between low-voltage logic controllers and higher-power bipolar loads.
