TPS65197BRUYR - 8-Channel LCD Level Shifter | Texas Instruments
MPN: TPS65197BRUYR ✓ نشطTPS65197BRUYR نظرة عامة
An LCD level shifter is a specialized interface IC that translates gate-driver signals to the voltage domain required by an LCD panel. In the broader electronics hierarchy, this device is a display interface and voltage-level translator within interface ICs and semiconductor power-management-adjacent signal conditioning. The TPS65197 combines eight signal channels, configurable charge sharing, and shutdown panel discharge to support TFT-LCD panel timing and gate-drive architectures.
The verified feature set centers on 8 independently addressed level-shifter channels, support for no, 2-channel, and 3-channel charge-sharing modes, and discharge of the panel to VGH when the device enters shutdown. These functions address the practical need to control gate-line transitions, reduce transition-load demand, and establish a defined off state for TFT-LCD panels. The 28-pin WQFN (RUY) package also supports compact display-controller designs where connector count and routing area are constrained.
The RUY package is a 4 mm by 4 mm WQFN outline with 28 pins and a thermal pad, combining a small footprint with direct PCB heat-spreading capability. Its exposed pad provides a thermal path to the board copper rather than relying only on package leads. Although this is principally a signal-interface device rather than a power semiconductor, the exposed pad must still be connected according to the manufacturer land pattern and thermal guidance to preserve electrical performance, assembly yield, and temperature reliability.
TPS65197BRUYR is appropriate for TFT-LCD monitor panels, industrial HMIs, small-format embedded displays, test equipment, and other systems requiring coordinated level translation, charge sharing, and controlled panel shutdown. Designers should match the panel's gate-line count, allowable charge-sharing mode, VGH operating behavior, signal timing, and shutdown requirements before finalizing a system design. The use of supported charge-sharing modes can lower effective switching load, while panel discharge provides a defined shutdown sequence.
PCB layout should keep the level-shifter outputs and VGH-related connections short, preserve the manufacturer's recommended copper and thermal-pad geometry, and maintain clean return paths beneath the device. Designers must also validate output timing against the target panel because no, 2-channel, and 3-channel operation are not interchangeable for every controller. Power sequencing should be coordinated with the display controller so VGH is not removed before the required panel-discharge interval has completed.
This page consolidates the verified TI product information, distributor availability, package details, pricing snapshot, selection guidance, and design considerations for TPS65197BRUYR. It also separates confirmed technical facts from parameters that require confirmation in the manufacturer datasheet, helping engineers evaluate panel compatibility without relying on assumptions.

التطبيقات النموذجية
TPS65197BRUYR مناسب لـ 6 التطبيقs: TFT-LCD Monitor Gate Drive, Industrial HMI Display, Embedded Small-Format Display, LCD Panel Power-Down Sequencing, Test and Measurement Instrument Display, Multi-Channel LCD Timing Controller.
TFT-LCD Monitor Gate Drive
The TPS65197BRUYR fits TFT-LCD monitor gate-drive circuitry because it combines eight level-shifter channels with selectable no, 2-channel, and 3-channel charge-sharing modes. These functions allow the display controller to coordinate gate-line transitions without implementing every translation and sharing function as separate discrete circuitry. The 28-pin WQFN (RUY) package also keeps the device compact for monitor-controller boards. Before layout approval, verify the panel's gate count, permitted charge-sharing mode, VGH requirements, and timing against the manufacturer datasheet.

Industrial HMI Display
An industrial human-machine interface can use the TPS65197BRUYR to organize panel-level shifting and controlled shutdown in a compact controller design. The eight channels support LCD gate-line control, while no, 2-channel, and 3-channel charge sharing provides configuration flexibility for different panel transition schemes. Shutdown discharge to VGH establishes the device's defined off behavior. Actual industrial deployment still requires confirmation of the operating-temperature limits and voltage ranges, which are not present in the supplied web snippets.
موصى به
Embedded Small-Format Display
The TPS65197BRUYR is suitable for embedded LCD systems where panel-control functionality must be concentrated without adding a large discrete gate-driver network. Eight level-shifter channels, configurable charge sharing, and panel discharge to VGH provide the core functions needed for coordinated panel operation. Its 4 mm by 4 mm WQFN (RUY) package helps preserve PCB area in compact equipment. Designers should reserve the exposed-pad copper according to the TI layout guidance and verify that the target panel's timing sequence is compatible with the selected charge-sharing mode.
موصى به
LCD Panel Power-Down Sequencing
TPS65197BRUYR can be used where the display system needs a defined panel-discharge operation during shutdown rather than leaving panel state dependent only on external passive components. Its panel-discharge-to-VGH feature works alongside eight level-shifter channels and selectable charge sharing. This makes it relevant to instrument, control-panel, and test-equipment designs that require repeatable display power sequencing. The shutdown delay, usable VGH conditions, and any required external components must be confirmed directly from the TPS65197 datasheet before firmware and hardware timing are finalized.
موصى به
Test and Measurement Instrument Display
The TPS65197BRUYR can support the display subsystem of a bench instrument by consolidating eight LCD level-shifter channels, charge-sharing control, and shutdown discharge in a single package. That integration helps the instrument maintain controlled panel transitions and a defined shutdown state while preserving board area. The exact suitability depends on the panel module's channel count, timing, VGH behavior, and operating environment. Because the verified snippets do not provide full electrical timing data, engineers should compare those panel requirements with the complete manufacturer specification rather than relying on the family-level feature description alone.
موصى به
Multi-Channel LCD Timing Controller
For controllers that manage several display lines, the TPS65197BRUYR offers eight level-shifter channels plus configurable charge-sharing modes to support controlled gate-line transitions. No charge sharing preserves the basic operating arrangement, while 2-channel and 3-channel modes support panel architectures that permit transition load to be shared across lines. The device's 28-pin WQFN (RUY) footprint supports compact controller layouts. Mode selection must be based on the target panel's electrical and timing rules because sharing more lines does not automatically improve performance or provide a universal functional advantage.

ملاحظات التصميم
Follow the manufacturer WQFN (RUY) land pattern exactly, including the exposed-pad opening, solder-mask definition, and paste pattern. The supplied web data confirms a 28-pin, 4 mm by 4 mm package but does not provide the land-pattern dimensions. Do not infer them from another WQFN-28 footprint. Preserve the exposed-pad connection and use a reflow profile appropriate for the package, because an incorrect thermal-pad aperture can cause voiding, solder-ball formation, or inconsistent assembly behavior.
Coordinate VGH generation, level-shifter enablement, panel charge sharing, and shutdown discharge as one sequencing problem. The verified TPS65197 feature set confirms discharge to VGH during shutdown, but the actual delays and voltage conditions are not present in the supplied snippets. Review the timing diagrams in the manufacturer datasheet and ensure the display controller does not change gate-line states or remove required panel biasing before the device has completed its defined shutdown sequence.
Do not select a charge-sharing mode solely from a generic desire to reduce transition load. The TPS65197BRUYR supports no, 2-channel, and 3-channel configurations, but the safe choice depends on the panel's gate architecture and timing requirements. Confirm whether adjacent or grouped channels may share charge, whether every channel supports the selected mode, and whether gate-driver timing must be adjusted. An unsupported sharing configuration could distort panel operation even though the IC itself operates normally.
Keep level-shifter and VGH-related routing compact, and provide an uninterrupted ground return beneath the device where the reference layout permits. Avoid routing high-current panel-driver loops across or immediately beneath sensitive gate-control traces. The exposed pad should be tied according to the TI recommendation rather than treated as an optional thermal feature. Because detailed high-voltage and signal-integrity limits were not included in the verified snippets, use the complete datasheet for spacing, slew-rate, and routing requirements.
