A8601KLPTR-T

Overview

The A8601KLPTR-T is a fixed-frequency, multiple-output LCD bias supply IC manufactured by Allegro MicroSystems. Designed for automotive applications, it provides five adjustable output voltages within a 4V to 5.5V input range. The device features a 28-TSSOP-EP package with exposed pad for enhanced thermal performance. It operates reliably across an extended temperature range from -40°C to +125°C and meets RoHS3 standards. This regulator integrates control and protection circuitry specifically optimized for next-generation car audio and infotainment display systems.

Feature Summary

• Integrates five independent adjustable output channels for comprehensive LCD bias generation
• Optimized for automotive infotainment and car audio display power requirements
• Includes integrated control and protection circuitry for system reliability
• Utilizes exposed pad TSSOP packaging to support efficient thermal dissipation

Applications

• Automotive LCD display bias supplies
• Car audio system power management
• Infotainment system voltage regulation
• TFT-LCD panel driver circuits

Procurement Notes

Verify the specific suffix KLPTR-T against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure the application environment remains within the specified -40°C to +125°C operating temperature range. Confirm that the input voltage stays between 4V and 5.5V to maintain proper regulation. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly processes.

Selection Notes

Select this component when designing power architectures for automotive displays requiring multiple regulated rails from a single low-voltage source. It is suitable for systems where space constraints favor a compact 28-pin solution over discrete regulator designs. Consider its fixed-frequency operation when evaluating electromagnetic interference (EMI) filtering needs. Verify that the five-channel output capability aligns with the specific voltage requirements of the target LCD panel.

Part Context

The A8601 belongs to Allegro's family of specialized power management ICs tailored for automotive electronics. It addresses the increasing complexity of modern vehicle interiors, which demand robust power delivery for high-resolution displays. As part of the A860x series, it complements other regulators designed for infotainment and instrument cluster applications, ensuring consistent performance under harsh automotive conditions.

Replacement Considerations

Public documentation identifies the A8600 as a related product in the same family. Designers should consult official substitution guides or contact Allegro MicroSystems directly to verify functional compatibility before replacing the A8601KLPTR-T with alternative components.
