A8603KESTR-R

Overview

The A8603KESTR-R is a specialized LCD converter regulator IC manufactured by Allegro MicroSystems. It features four adjustable outputs and operates within an input voltage range of 3V to 10V. The device is housed in a 24-QFN (4x4) package with exposed pad for surface mount installation. Designed for automotive applications, it meets AEC-Q100 standards and supports a wide operating temperature range from -40°C to 125°C.

Feature Summary

• Provides four independently adjustable output voltages suitable for complex LCD biasing requirements.
• Engineered specifically for LCD converter applications within automotive environments.
• Complies with AEC-Q100 qualification standards for automotive grade reliability.

Applications

• LCD converter circuits
• Automotive display systems

Procurement Notes

Verify the complete part number including suffixes such as REEL or CUT TAPE to ensure correct packaging configuration. Confirm RoHS3 compliance status and湿气敏感性等级 (MSL) ratings prior to PCB assembly planning. Ensure the supplier provides valid traceability documentation consistent with automotive quality requirements.

Selection Notes

Select this component when designing automotive LCD driver stages requiring multiple regulated rails from a single low-voltage source. The 24-QFN footprint necessitates careful thermal management design due to the exposed pad requirement. Verify that the required output voltage ranges fall within the adjustable limits supported by the internal regulation architecture.

Part Context

This device belongs to the A8603 series of power management integrated circuits focused on display driving solutions. It serves as a dedicated solution for generating stable bias voltages in liquid crystal displays used in automotive instrumentation and infotainment systems.

Replacement Considerations

Consult official Allegro MicroSystems documentation for verified substitute part numbers. Do not assume functional compatibility with other series without explicit manufacturer confirmation.
