TPS65192RHDR - 9-Channel LCD Level Shifter | Texas Instruments
MPN: TPS65192RHDR ✓ نشطTPS65192RHDR نظرة عامة
An LCD level shifter is an interface IC that translates voltage-domain signals between a display timing controller and source and gate driver circuits. Within the broader semiconductor hierarchy, it belongs to the voltage-level translation and display-interface ecosystem rather than the power-management regulator or processor categories. Its purpose is to preserve signal timing and establish the voltage swing required by display electrodes while limiting electrical stress on the controller.
The TPS65192 provides nine independent level-shifting channels, gate voltage shaping, and discharge functions. These features support LCD panels used in televisions and monitors. The 28-pin VQFN package measures 5 x 5 mm, allowing a compact display-interface implementation while exposing separate display-signal, supply, ground, and control connections. The stated -40°C to +85°C range supports use across industrial and commercial temperature environments.
Architecturally, the device is divided into two channel groups to support the timing relationships of an LCD panel. The first seven channels use the VGH1 and VGL supply domain, as identified by Texas Instruments. The other two channels form the second group. Gate voltage shaping and active discharge functions help the display interface maintain defined output states during signal transitions and panel-specific drive sequences.
Typical applications include LCD television panels, computer monitors, timing-controller interfaces, large-format displays, and other TFT-LCD systems in which source or gate lines must be translated between logic and panel voltage domains. The device is particularly relevant when the timing controller cannot directly drive the voltage levels required by the LCD panel.
Designers should treat the LCD panel requirements as the controlling specification. Verify VGH1, VGL, the second channel-group supply, signal timing, and output levels against the manufacturer datasheet. Place bypass capacitors close to the relevant supply pins and route high-voltage display-drive traces to minimize coupling into adjacent logic channels. The 5 x 5 mm VQFN footprint also requires thermal-aware layout and exposed-pad soldering verification.
This page combines the verified Texas Instruments product description, package and temperature information, distributor availability references, honest pricing status, and a constrained drop-in comparison. It also identifies the electrical and pin-level data that must be confirmed in the manufacturer datasheet before layout or production release.

التطبيقات النموذجية
TPS65192RHDR مناسب لـ 6 التطبيقs: LCD Television Panel Interface, Computer Monitor Level Shifting, LCD Timing Controller Interface, Large-Format TFT-LCD Display, Display Panel Gate-Line Control, Industrial Display Control System.
LCD Television Panel Interface
The TPS65192RHDR fits the signal boundary between an LCD television timing controller and the panel's high-voltage drive circuitry. Its 9 level-shifting channels translate timing-controller logic signals into the higher voltage levels required by the display, while gate voltage shaping and discharge functions support defined panel drive states. The device is organized into two groups, with channels 1 through 7 assigned to the VGH1 and VGL supply domain. In a television design, that organization can simplify routing and reduce the number of separate interface devices. The 28-pin 5 x 5 mm VQFN also preserves board area in space-constrained display electronics. Before layout, engineers must verify the exact channel assignments, output voltage limits, timing, and supply requirements for the selected television panel against the manufacturer datasheet.

Computer Monitor Level Shifting
The TPS65192RHDR is appropriate for an LCD monitor when the timing controller cannot directly produce the panel gate-drive voltage levels. Its 9 channels provide a dedicated interface between low-voltage control logic and the display electrode drive domain, with channels 1 through 7 powered from VGH1 and VGL. Gate voltage shaping can help establish the intended waveform, while the discharge function assists in returning outputs to a defined state. The -40°C to +85°C operating range covers industrial and commercial monitor environments. In a compact monitor controller, the 28-pin 5 x 5 mm VQFN package limits board footprint but requires careful exposed-pad layout and thermal verification. The engineer should confirm channel direction, signal timing, and all voltage domains in the TI datasheet before releasing the PCB.

LCD Timing Controller Interface
The TPS65192RHDR can serve as the dedicated level-translation stage between an LCD timing controller and panel drive signals. Its 9 channels separate the low-level logic interface from the panel's higher operating voltages, and the two-group organization maps channels 1 through 7 to VGH1 and VGL while providing a second group for channels 8 and 9. This arrangement is useful when timing-controller I/O voltage, panel gate voltage, and source-level requirements differ. Gate voltage shaping and discharge functions make the IC more than a simple bidirectional translator for LCD timing applications. The 5 x 5 mm VQFN supports compact controller boards, although high-voltage and low-voltage routing must remain separated. Use the manufacturer pinout and timing diagrams to validate signal mapping, output transitions, and bypass-capacitor placement.

Large-Format TFT-LCD Display
The TPS65192RHDR is suited to TFT-LCD systems in which a controller board must translate multiple logic signals into panel-level drive voltages. Nine channels allow the interface to cover a defined group of source or gate lines, while the separated supply groups support the different voltage domains commonly required by LCD electrodes. Gate voltage shaping and discharge functions are particularly relevant when the panel expects controlled gate transitions or defined inactive states. The -40°C to +85°C specification makes the device appropriate for controlled industrial display environments, but temperature and power conditions must still be verified at the system level. Its compact 28-pin VQFN package reduces connector and routing congestion beside the timing controller. Final implementation should validate propagation delay, channel direction, panel timing, and all high-voltage clearances from the TI datasheet.

Display Panel Gate-Line Control
The TPS65192RHDR can support the gate-line portion of an LCD panel interface because it provides nine level-shifting channels together with dedicated gate voltage shaping and discharge behavior. Channels 1 through 7 are explicitly associated with the VGH1 and VGL domain, allowing the timing-controller signals to be converted for compatible panel drive circuits. The second group provides two additional channels for the remaining interface functions. This structure allows panel designers to consolidate level translation and output-state management in one device instead of using separate translators where the requirements align. The 5 x 5 mm 28-pin VQFN is useful in display boards with limited routing space, but its exposed thermal pad must be connected according to the manufacturer land pattern. Verify gate timing, discharge behavior, voltage limits, and channel assignments against the selected panel's requirements.

Industrial Display Control System
The TPS65192RHDR can be used in an industrial display controller when low-voltage control logic must drive an LCD panel across a larger voltage domain. Its specified -40°C to +85°C range supports controlled industrial equipment, and the 9-channel level shifter reduces the number of discrete translation stages needed when all required channels fit the device architecture. Gate voltage shaping and discharge functions support predictable panel states, while the 28-pin 5 x 5 mm VQFN keeps the interface compact. Industrial designs still require careful review of temperature rise, power-supply headroom, signal integrity, and high-voltage creepage around the controller. Because the verified snippets do not expose all voltage and timing limits, engineers should use the official TI datasheet for channel direction, supply-domain values, output behavior, and recommended application circuitry before qualifying the design.

ملاحظات التصميم
Place the bypass capacitors associated with VGH1, VGL, and the second channel-group supply as close as practical to their TPS65192RHDR pins. Keep the high-voltage display-drive traces away from low-level timing-controller nets to reduce capacitive coupling. Route and place the device using the official TI land pattern rather than a generic 28-pin VQFN footprint, because exposed-pad, mask, and paste details can affect assembly performance.
Validate every source and gate line for propagation delay, transition time, and voltage limits using the manufacturer timing information. The verified excerpts identify the channel grouping but do not provide delay figures, so engineers must not infer timing equivalence from the package alone. Keep connectors and panel routes away from the logic-side nets, provide a continuous return path, and test the assembled board with the intended LCD panel rather than a simplified load alone.
Confirm the voltage and current requirements for VGH1, VGL, and the remaining channel-group supply before enabling the display. The TPS65192RHDR translates logic signals into panel-level domains, so sufficient supply headroom and sequencing are essential. Check discharge currents, bypass-capacitor selection, and startup behavior in the manufacturer datasheet, especially when the panel can be disconnected or partially powered during service.
The 28-pin RHD VQFN uses a compact 5 x 5 mm body and includes a package thermal path that must be implemented on the PCB. Use the datasheet's exposed-pad soldering and thermal-land instructions, and evaluate temperature rise using the actual copper area and enclosure. The verified -40°C to +85°C range describes environmental capability; it does not guarantee that every board layout will maintain the required junction temperature at maximum display-drive activity.
