TPS65197BRUYT - 8-Channel LCD Level Shifter | Texas Instruments
Référence : TPS65197BRUYT ✓ ActifTPS65197BRUYT Présentation
An LCD level shifter is a voltage-interface IC used between a display timing controller and the high-voltage gate-driver inputs of an LCD panel. Within the signal-chain hierarchy, it belongs to interface ICs and video ICs rather than a display driver or low-voltage digital logic device. Its principal purpose is to translate low-voltage timing signals while coordinating charge sharing and panel discharge, helping the display system reach a defined state during power transitions.
The TPS65197 provides eight level-shifting channels together with clock outputs that support normal operation, two-channel charge sharing, and three-channel charge sharing. The manufacturer describes it as an eight-channel device intended for notebook, monitor, and television LCD panels. Charge-sharing support reduces the number of high-voltage gate-driver components required in suitable panel architectures, while the panel-discharge function provides a controlled path to VGH during shutdown.
The 16.5 V minimum and 45 V maximum supply specification places the device in the high-voltage interface category used by LCD gate-driver systems. The exact channel-level voltage ranges, output-current limits, timing values, and enable or mode details were not present in the supplied verified excerpts and therefore must be checked against the complete manufacturer datasheet before layout or design release.
Typical uses include notebook LCD panels, desktop monitors, television panels, and other display systems that translate timing-controller outputs into GIP gate-drive signals. Designers should pay particular attention to charge-sharing mode selection, shutdown sequencing, VGH discharge behavior, exposed-pad thermal management, and the recommended input and output timing layout.
The 28-pin 4 mm by 4 mm WQFN package supports compact display-controller boards, but its fine pitch and exposed pad require disciplined PCB layout. Confirm the exact RUY land pattern, thermal-pad connection, voltage rails, and timing constraints using the current TI datasheet and application information before production.
This page consolidates verified manufacturer and distributor information with package details, procurement data, display-use guidance, and explicit identification of specifications that still require confirmation. It distinguishes verified facts from missing technical parameters so engineers can assess suitability without relying on unverified assumptions.

Applications typiques
TPS65197BRUYT convient pour 6 applications: Notebook LCD Panels, Desktop Monitor Panels, Television LCD Panels, Industrial LCD Displays, Portable Display Systems, External Display Adapters.
Notebook LCD Panels
The TPS65197BRUYT fits notebook LCD architectures that require timing-controller signals to be translated into high-level GIP gate-drive signals. Its eight channels and support for normal, 2-channel, and 3-channel charge sharing allow the panel interface to be adapted without using a separate generic level-shifting arrangement. The 16.5 V to 45 V operating range is suited to the high-voltage side of an LCD gate-driver system, while the -40 °C to 85 °C specification covers broad product environments. Designers must still match the RUY pinout, panel timing, CLKOUTx requirements, VGH shutdown behavior, and charge-sharing mode to the target notebook panel before release.
Recommandé
Desktop Monitor Panels
The TPS65197BRUYT is applicable to desktop monitor panels where a timing controller must drive GIP logic through a higher-voltage interface. Its support for 2-channel and 3-channel charge sharing can reduce the gate-driver component count in compatible panel topologies, while CLKOUTx outputs provide dedicated clock distribution. The 28-pin 4 mm by 4 mm WQFN package supports compact controller-board layouts but requires careful exposed-pad and high-voltage clearance. The 16.5 V minimum supply and -40 °C to 85 °C range must be checked against the complete monitor power architecture, panel VGH timing, and shutdown requirements.
Recommandé
Television LCD Panels
The TPS65197BRUYT can serve large television LCD panels that use GIP timing and benefit from selectable charge-sharing behavior. Eight level-shifting channels provide the interface between the timing controller and high-level panel signals, while two-channel and three-channel charge sharing can simplify suitable gate-driver configurations. Panel discharge to VGH during shutdown adds a controlled power-transition function to the display interface. Television designers must verify the absolute-maximum ratings, signal timing, thermal performance of the 28-pin WQFN package, and compatibility with the selected panel's gate-driver and VGH power sequence before incorporating the device.
Recommandé
Industrial LCD Displays
The TPS65197BRUYT is suitable for industrial LCD displays using high-voltage GIP signals when the operating environment falls within its specified -40 °C to 85 °C range. The eight-channel architecture and selectable charge-sharing modes support panel-interface optimization, while panel discharge to VGH during shutdown helps establish a controlled display state. Industrial designs may operate from noisy or wide-range power systems, so designers should verify input transients, supply sequencing, and the device's complete absolute-maximum limits. The compact RUY package also requires thermal analysis of the exposed pad under the enclosure's actual airflow and ambient-temperature conditions.
Recommandé
Portable Display Systems
TPS65197BRUYT can be used in portable display systems whose LCD panels require a dedicated high-voltage logic interface and charge-sharing capability. Its 4 mm by 4 mm WQFN footprint helps conserve board area, and the CLKOUTx outputs support clock distribution where required by the panel timing architecture. The 16.5 V to 45 V supply range is designed for the gate-drive side rather than direct battery-rail operation, so the preceding power-conversion stage must generate the required interface supply. Battery-driven designs should prioritize shutdown sequencing, VGH discharge behavior, board-space efficiency, and verified operating-temperature suitability over generic level-shifter simplicity.
Recommandé
External Display Adapters
The TPS65197BRUYT is appropriate for an external display adapter that translates timing-controller outputs into the high-level signals required by a compatible GIP LCD. Eight channels and multiple charge-sharing options give the adapter a path to support different panel architectures without substituting several unrelated interface functions. The 28-pin WQFN package enables a compact adapter board, although assembly must account for fine lead pitch, exposed-pad soldering, and high-voltage creepage around the 45 V maximum supply. Integration testing should verify level translation, CLKOUTx behavior, charge-sharing transitions, and shutdown discharge to VGH with the intended panel.

Notes de conception
Use the official TI RUY package drawing as the authority for land geometry, exposed-pad dimensions, and pin numbering. The verified excerpts confirm a 28-pin 4 mm by 4 mm WQFN package but do not provide a complete numbered pin table. Place the device near the display timing-controller and GIP interface, route high-voltage supply and VGH-related paths with suitable clearance, and avoid introducing long stubs into timing-critical channels.
Design the 16.5 V to 45 V interface supply with startup, shutdown, and transient behavior appropriate for the LCD gate-driver system. Confirm the complete datasheet's absolute-maximum voltage, current, and sequencing limits before adding surge protection or clamping. The panel-discharge-to-VGH function should be evaluated together with the panel and power-supply shutdown sequence so that stored gate voltage is discharged under controlled conditions.
The 28-pin WQFN relies on its exposed pad for heat spreading, but verified thermal-resistance figures were not supplied. Do not infer acceptable dissipation from package size alone. After obtaining the manufacturer thermal data, estimate worst-case junction temperature using the actual copper area, board construction, airflow, ambient temperature, and the dissipation associated with the selected LCD operating mode.
Do not treat a generic eight-channel logic level shifter as a functional equivalent without checking channel voltage ranges, CLKOUTx behavior, charge-sharing logic, panel discharge, and the RUY pin assignment. Charge-sharing modes must also be compatible with the panel's gate-driver topology. The supplied alternative searches did not verify a separate drop-in replacement, making careful manufacturer-datasheet review more important than relying on package similarity alone.
Informations de conformité
The supplied verified excerpts do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than assumed.
