A6833SEP-T

Overview

The A6833SEP-T is a DABiC-5 series integrated circuit featuring 32-bit serial input latched sink drivers. It operates with a logic supply range of 3V to 5.5V and supports data input rates up to 10 MHz. The device utilizes Darlington current-sink outputs with a minimum output breakdown voltage of 30V and a maximum output current of 125mA. It is housed in a 44-PLCC package (16.59x16.59mm) designed for surface mount installation. The component functions within an operating temperature range of -20°C to 85°C.

Feature Summary

• Integrates Schmitt trigger inputs to enhance noise immunity during signal processing.
• Employs low-power CMOS logic and latches for efficient power management.
• Features non-inverting input types for straightforward interface integration.

Applications

• Vacuum fluorescent display driver systems
• Dot matrix display interfaces
• General purpose load driving applications

Procurement Notes

Verify the specific suffix configuration against official datasheets, as variations exist between tape-and-reel and tube packaging options. Confirm RoHS3 compliance status and moisture sensitivity level requirements prior to procurement. Check for obsolescence notices or product change notifications regarding package updates. Ensure compatibility with existing PCB footprints for the 44-LCC J-leads form factor.

Selection Notes

Select this component when a high-density serial interface is required for driving multiple loads simultaneously. The 1:32 input-to-output ratio simplifies control logic by reducing pin count compared to parallel solutions. Consider the bipolar output type and low-side configuration for appropriate load matching. Evaluate thermal performance within the specified ambient temperature range for the target enclosure.

Part Context

This part belongs to the Allegro MicroSystems DABiC-5 family of latch drivers. It shares architectural similarities with the A6832 series but differs in maximum load voltage ratings. The A6833 is specifically engineered for applications requiring robust sink capabilities with serial data handling. It complements other Allegro PMIC solutions for comprehensive power distribution management.

Replacement Considerations

The A6832SEPTR-T is a documented alternative within the same family, offering identical pinout and functionality with a higher 40V load voltage rating. Verify that the increased voltage tolerance does not impact system design constraints before substitution.
