LC75809PTS-H

Display Drivers Overview

The LC75809PTS-H is a microprocessor-controlled LCD driver manufactured by onsemi, designed for general-purpose applications. It supports 1/4 duty and 1/3 duty drive schemes for segment LCDs. The component operates within a supply voltage range of 2.0 V to 6.0 V. It features an internal oscillator and requires minimal external components. The device is housed in a 28-pin SSOP package and is classified as End-of-Life with restricted availability.

Display Drivers Feature Summary

• Microprocessor interface for flexible control
• Supports 1/4 and 1/3 duty waveforms
• Internal oscillator reduces external component count
• Low voltage operation capability

Display Drivers Applications

• General-purpose segment LCD displays
• Consumer electronics instrumentation panels
• Industrial control interfaces

Display Drivers Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Distribution channels indicate restricted supply status, meaning standard inventory replenishment is not guaranteed. Procurement should focus on verifying current stock availability through authorized distributors or approved secondary sources. Designers must assess long-term supply chain risks before finalizing this part number for new production runs due to its discontinued status.

Display Drivers Selection Notes

Select this driver when a low-cost, microprocessor-compatible solution for simple segment LCDs is required. It is suitable for designs prioritizing minimal external circuitry and low power consumption. Engineers should verify that the target display matches the supported duty ratios and voltage levels. Given the EOL status, alternative parts with similar pinouts and functionality should be evaluated for future-proofing requirements.

Display Drivers Part Context

The LC75809 belongs to onsemi's legacy LCD driver portfolio, intended for basic display driving tasks. It sits alongside other discontinued drivers like the LC75839 series. These components were widely used in cost-sensitive consumer devices before being phased out in favor of more integrated or newer generation solutions. The 'H' suffix typically denotes specific environmental compliance or packaging variations within the series.

Display Drivers Replacement Considerations

As an End-of-Life product, direct substitutes are not officially listed by onsemi. Engineers should evaluate generic LCD drivers from other manufacturers that support 1/4 or 1/3 duty cycles and SSOP-28 packages. Key parameters to match include operating voltage range, interface type, and output current capabilities. Cross-referencing pinouts is essential to ensure mechanical compatibility.
