TPS65197RUYR - 8-Channel LCD Level Shifter | Texas Instruments
N.º da peça: TPS65197RUYR ✓ AtivoTPS65197RUYR Visão geral
TPS65197RUYR belongs to the interface IC and display-driver ecosystem. A level shifter is an interface IC that translates voltage domains while preserving signal timing and logic function. In an LCD system, the timing controller operates at lower logic voltages, while GIP row and column driver circuits may require elevated panel voltages. The TPS65197 provides eight channels for this signal conversion and supports panel-specific charge-sharing sequences that help control panel charging and discharge behavior.
The principal feature set includes eight level-shifting channels, support for no-charge-sharing, 2-channel charge-sharing, and 3-channel charge-sharing operation, and a dedicated panel-discharge function. The manufacturer product page identifies the device as an 8-channel level-shifter supporting 2-channel and 3-channel charge-sharing and panel discharge in the WQFN (RUY) package with 28 pins.
Because GIP panels can accumulate charge and generate transient loads during startup, the charge-sharing architecture is important. The supported operating modes let a system select a charging strategy according to panel timing requirements rather than using a simple fixed level translation approach. The shutdown discharge path provides a defined mechanism for returning panel nodes toward VGH during power-down.
Typical uses include notebook computer LCD panels, desktop monitors, television panels, and other GIP-based display systems. The device is most appropriate when the source logic levels, panel gate-drive levels, supported charge-sharing sequence, and shutdown behavior must all be evaluated together. A replacement should not be selected solely by channel count; the timing of each output, panel discharge behavior, voltage ratings, and board footprint must be confirmed against the original design.
This page combines the verified manufacturer description, distributor package information, drop-in alternatives, and engineering-oriented design guidance. The 28-pin WQFN footprint, exposed thermal pad, high-speed panel signals, and power-sequencing requirements should be reviewed against the complete manufacturer datasheet before layout or replacement qualification.

Aplicações típicas
TPS65197RUYR é adequado para 6 aplicaçãos: Notebook LCD GIP Panel Interface, Desktop Monitor Panel Interface, Television GIP Display Interface, Industrial HMI Panel Interface, Automotive Display Interface, Small Display Controller Interface.
Notebook LCD GIP Panel Interface
The TPS65197RUYR fits notebook LCD designs that use a timing controller to generate GIP row and column signals at logic levels different from the panel gate-driver levels. Its eight channels provide a defined translation path for the display timing signals, while the 2-channel and 3-channel charge-sharing options support controlled panel charging. The 28-pin WQFN (RUY) package also supports compact display-board layouts. Designers should verify the timing-controller output levels, panel VGH behavior, output transition requirements, and exposed-pad layout against the manufacturer datasheet.
Recomendado
Desktop Monitor Panel Interface
TPS65197RUYR is applicable to desktop monitor electronics where a timing controller drives a GIP LCD panel through elevated gate voltages. The eight-channel architecture maps multiple timing signals while charge-sharing control helps manage panel charging conditions. Its shutdown discharge-to-VGH behavior is relevant when the display must return panel nodes to a defined condition during power-down. For monitors, the design team should confirm output timing, panel-specific charge-sharing sequence, signal integrity at the connector and panel traces, and thermal performance of the compact WQFN package.
Recomendado
Television GIP Display Interface
The TPS65197RUYR can support television panel interfaces that require multiple logic-to-gate-level translations and controlled charge sharing. Eight channels suit timing-controller signals distributed to GIP driver circuits, while the supported 2-channel and 3-channel methods provide flexibility for the panel charging strategy. The 4 mm by 4 mm WQFN (RUY) package helps maintain compactness in display electronics. Integration still requires verification of absolute maximum ratings, timing margins, VGH discharge behavior, and PCB return paths under the television power-supply environment.
Recomendado
Industrial HMI Panel Interface
Industrial human-machine-interface displays often use timing controllers and GIP panels with voltage-domain requirements that differ from the controller logic levels. TPS65197RUYR offers eight translated channels plus selectable charge-sharing behavior for panel integration, making it relevant to industrial HMIs with fixed timing and defined shutdown expectations. The panel-discharge-to-VGH function can simplify controlled shutdown sequencing when validated for the specific panel. Engineers should account for long operating periods, temperature range, display connector losses, and the manufacturer-specified operating limits before design freeze.
Recomendado
Automotive Display Interface
TPS65197RUYR may be evaluated for automotive display interfaces where a controller drives LCD or related panel circuitry through GIP timing signals. Its eight-channel level-shifting function and charge-sharing modes support panel-specific sequencing, while the shutdown discharge function addresses controlled panel power-down. The compact 28-pin WQFN RUY package is suitable for dense electronic-control-unit layouts. Automotive suitability, including any AEC-Q100 grade, temperature range, transient tolerance, and display-specific qualification, is not established by the supplied data and must be verified before production use.
Recomendado
Small Display Controller Interface
TPS65197RUYR is suitable for small embedded display systems where the controller outputs low-voltage timing signals and the panel requires higher gate-drive levels. Eight channels allow multiple display timing outputs to be translated, and the available charge-sharing methods provide a way to align charging behavior with the panel architecture. The 4 mm by 4 mm WQFN package preserves board area in compact control boards. The implementation must confirm channel direction, logic thresholds, output timing, power rails, and exposed-pad thermal design using the current manufacturer documentation.

Notas de projeto
Place the TPS65197RUYR close to the display timing-controller outputs and the target panel interface to minimize trace length on high-speed level-shifting signals. Route each channel with a continuous return path and avoid splitting ground or power planes beneath the package. Because the device uses a 28-pin WQFN package with an exposed pad, use the manufacturer land-pattern and exposed-pad guidance exactly rather than relying on a generic WQFN footprint.
Decouple the device supply rails directly at the package with the capacitance and voltage rating specified in the current TI datasheet. Keep the input, output, and panel-discharge loops compact, and verify that the timing controller and GIP panel rails remain within the device's absolute maximum and operating limits. The supplied verified data confirms the function and package but does not provide numeric voltage limits, so those values must not be guessed during schematic review.
Do not treat TPS65197RUYR as a generic bidirectional logic translator. Its intended role is an LCD level shifter with defined charge-sharing and shutdown-discharge behavior. Confirm channel direction, output levels, propagation timing, charge-sharing mode, and VGH discharge timing against the panel timing specification. The verified data does not include the complete pin table, so a footprint-only replacement can create panel malfunction even when the package appears identical.
The 4 mm by 4 mm WQFN package provides limited board area for heat removal, and the exposed pad is the principal thermal path. Provide uninterrupted ground-plane connection under the pad, follow the TI solder-mask and paste-land pattern, and use the package thermal data when available. Display systems can place substantial switching activity near the level shifter, so power and signal integrity should be checked together rather than treating the device as thermally isolated.
Evaluate rising and falling edges at the panel connector, not only at the timing-controller pins. Charge-sharing transitions can create timing and crosstalk effects that depend on panel capacitance and trace topology. Use the manufacturer-recommended external components and controlled impedance routing where specified, and compare the selected replacement against the original output timing and charge-sharing sequence before releasing a PCB revision.
