TPIC6B596N

Overview

The TPIC6B596N is an 8-bit shift register peripheral driver from the Texas Instruments TPIC series. It features open-drain outputs capable of driving high-voltage loads up to 50V with a maximum current of 1A per channel. The device operates on a single supply voltage ranging from 4.5V to 5.5V and includes integrated transient voltage suppression for robust protection. It utilizes standard serial data input, clock, and latch control signals to manage parallel output states.

Feature Summary

• High-current open-drain outputs designed for direct drive of inductive or resistive loads
• Integrated transient voltage suppression to protect against load dump and switching spikes
• Serial-to-parallel conversion with registered parallel outputs for stable data holding

Applications

• Solenoid and valve control systems
• Relay driver circuits
• LED matrix lighting arrays

Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-20 package variant when sourcing. Confirm RoHS compliance status as manufacturing processes may vary by production batch. Ensure the design accommodates the thermal requirements associated with 1A continuous output current per channel.

Selection Notes

Select this component for applications requiring high-side or low-side switching of heavy loads directly from a microcontroller. The integrated protection reduces external component count compared to discrete solutions. Consider the PDIP-20 package constraints if surface-mount space is limited.

Part Context

This part belongs to the TPIC6B59x family of high-current shift registers. It shares functional similarities with the TPIC6B595 but offers higher current handling capabilities suitable for automotive and industrial environments where robustness against electrical noise is critical.

Replacement Considerations

TPIC6B595N serves as a lower-current alternative within the same family. Verify pin compatibility and ensure the replacement meets the specific voltage and current requirements of the target application.
