A6832SEPTR-T

Overview

The A6832SEPTR-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 capable of delivering up to 125mA each. The device operates on a supply voltage between 3V and 5.5V and supports a maximum load voltage of 40V. It utilizes both parallel and serial interfaces for control. The component is housed in a 44-PLCC package with J-leads, measuring 16.59x16.59mm, and functions within an ambient temperature range of -20°C to +85°C.

Feature Summary

• Integrates 32 independent low-side bipolar outputs for high-channel density control
• Supports flexible configuration through combined parallel and serial interface options
• Provides non-inverting input logic for straightforward signal processing

Applications

• Automotive lighting systems requiring multi-zone control
• Industrial load distribution networks
• High-density LED matrix drivers

Procurement Notes

Verify the specific suffix SEPTR-T against official datasheets to confirm the tape-and-reel packaging format and lead finish specifications. Ensure that the 44-PLCC footprint matches the target PCB design constraints. Confirm RoHS3 compliance status if required by local regulations. Check for any recent product change notices regarding package dimensions or material composition updates.

Selection Notes

Select this component when a high number of individually addressable low-side switches are required within a single integrated circuit. The 1:32 ratio reduces board space compared to discrete solutions. Consider the 40V load voltage rating and 125mA output current capability against the specific load requirements. Evaluate the thermal performance within the specified operating temperature range for the intended enclosure environment.
