LM8500HVA9

Overview

The LM8500HVA9 is a four-wire resistive touchscreen controller manufactured by National Semiconductor, now part of Texas Instruments. This integrated circuit features an integrated brownout detector to ensure reliable operation during power supply fluctuations. It is designed for applications requiring precise touch input processing in portable electronic devices. The component operates within standard industrial temperature ranges and utilizes surface-mount packaging suitable for high-density circuit board layouts.

Feature Summary

Four-wire resistive touchscreen interface controller
Integrated brownout detection circuit
Designed for portable device touch input processing

Applications

Portable consumer electronics with resistive touchscreens
Industrial control panels using four-wire resistive interfaces
Embedded systems requiring touch input functionality

Part Context

The LM8500 series includes the LM8300 and LM8500 variants, both serving as four-wire resistive touchscreen controllers with brownout protection. The LM8500HVA9 is a specific package variant within this family, sharing core functional specifications with other members like the LM8500IMT9B/NOPB while differing in physical housing and pin configuration.

Replacement Considerations

The LM8500IMT9B/NOPB is listed as a similar part number from Texas Instruments. Verify pin compatibility and package dimensions before substitution. Alternative solutions from manufacturers such as Semtech (e.g., SX8651) offer multitouch capabilities but may require significant design changes due to different interface protocols.
