TPS65193RGER

Overview

The TPS65193RGER is a dual high-voltage scan driver designed for TFT-LCD applications. It integrates two independent scan drivers capable of generating gate drive voltages up to 24V and negative gate off voltages down to -8V. The device operates from a single low-voltage supply input ranging from 2.7V to 5.5V, eliminating the need for external charge pumps or bootstrap circuits. It features adjustable output voltage levels via external resistors and includes protection mechanisms such as thermal shutdown and under-voltage lockout.

Feature Summary

• Dual integrated high-voltage scan drivers for TFT-LCD panel gate driving
• Single-supply operation compatible with standard logic levels
• Adjustable positive and negative gate voltage outputs
• Integrated thermal shutdown and under-voltage lockout protection

Applications

• TFT-LCD panel gate driver circuits
• Mobile phone display modules
• Portable media player screens
• Industrial LCD control boards

Procurement Notes

Verify the specific suffix RGER against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference the RoHS status and lead-free designation with the latest environmental compliance documentation provided by Texas Instruments before finalizing procurement orders.

Selection Notes

Select this component when designing TFT-LCD systems requiring dual independent gate drive channels without external inductors. It is suitable for applications needing adjustable VGH and VGL levels derived from a single low-voltage rail. Consider its thermal performance and operating temperature range relative to your enclosure constraints. Verify that the required gate drive frequency and load capacitance fall within the device's specified operational limits.

Part Context

This part belongs to the TPS6519x family of LCD bias controllers from Texas Instruments. It complements other components like level shifters and source drivers to form a complete display driving solution. The series is optimized for portable electronics where space and power efficiency are critical design parameters.

Replacement Considerations

Check for direct pin-to-pin replacements within the TPS6519x family, such as the TPS65190 or TPS65191, depending on channel count requirements. Verify functional equivalence regarding voltage ranges and drive capabilities before substitution.
