Product details
Overview
TPS65192RHDR from Texas Instruments is a 9-channel LCD gate driver level shifter with integrated gate voltage shaping and panel discharge functions. It converts T-CON logic-level signals to high-voltage gate drive levels (VGH1/VGH2 up to +38 V, VGL down to –13 V), supports 4- and 6-phase timing architectures, and delivers >500 mA peak output current per channel for Gate-in-Panel (GIP) LCD TV and monitor applications.
For engineers reviewing the TPS65192RHDR datasheet, TPS65192RHDR pinout, TPS65192RHDR application, or TPS65192RHDR equivalent, key selection considerations include dual-group 7+2 channel architecture, independent VGH1/VGH2 supplies, gate shaping on channels 1–6, DISCHARGE/VSENSE-controlled power-down sequencing, and QFN-28 thermal performance under capacitive panel loads.
Technical Context
The TPS65192RHDR implements two independent level-shifter groups: channels 1–7 powered by VGH1/VGL, and channels 8–9 powered by VGH2/VGL. Each group uses low-impedance MOSFET output stages enabling fast switching-rise/fall times as low as 3 ns (CL = 8 pF) for channels 1–7 and sub-5 ns for channels 8–9.
Gate voltage shaping is implemented via dedicated FLK1–FLK3 inputs controlling channels 1–6 using external RE resistor networks; the DISCHARGE function activates when VSENSE falls below 1.5 V (±0.225 V hysteresis), driving the panel to VGH1 during power-down. Propagation delay is 32 ns (rising/falling, CL = 8 pF) for channels 1–7 and 19–28 ns for channels 8–9.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VGH1/VGH2 Range | +12 V to +38 V - enables direct interface with high-voltage GIP panels requiring robust gate-on voltage swing |
| VGL Range | –13 V to –2 V - supports deep negative biasing needed for gate-off voltage in large-format LCDs |
| Output Current (Peak) | ±650 mA (channels 1–7), ±250 mA (channels 8–9) - sustains fast slew rates into typical 4.7 nF panel capacitances |
| Rise/Fall Time (CL = 4.7 nF) | 275–520 ns (rises), 220–370 ns (falls) for channels 1–7 - ensures sharp edge fidelity for high-resolution timing control |
| Propagation Delay | 60 ns (CL = 150 pF), 32 ns (CL = 8 pF) - guarantees tight skew control across multi-phase CLK/ODD/EVEN signal chains |
| VSENSE Threshold | 1.5 V (±0.225 V) - triggers DISCHARGE output at precise panel voltage decay point for reliable power-down sequencing |
| Package | 28-pin 5×5 mm QFN with exposed thermal pad - provides RθJA = 35°C/W and supports >3.5 W continuous dissipation at TA ≤ 25°C |
Pinout & Package
TPS65192RHDR is housed in a 28-pin VQFN (RHD) package with an exposed thermal die pad connected to VGL. The package features 0.5 mm pitch, wettable flanks, and JEDEC-compliant reflow profile (MSL Level-2, 260°C peak).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN9 | Logic-level input | Accepts 3.3 V CMOS/TTL signals from T-CON; unused inputs must be tied to GND |
| OUT1–OUT7 | High-side gate drive output | Drives LCD panel gates with VGH1/VGL rails; supports gate shaping via FLKx and RE |
| OUT8, OUT9 | Secondary gate drive output | Powered by VGH2/VGL; no gate shaping support; used for START/ODD/EVEN or auxiliary timing signals |
| DISCHARGE | Panel discharge output | Active-high open-drain output tracking VGH1 during power-down when VSENSE < 1.5 V |
| FLK1–FLK3 | Flicker clock input | Controls gate shaping timing for channel pairs (1/4, 2/5, 3/6); unused pins tied to GND |
| RE | Gate shaping discharge resistor node | Connects external resistor network to set decay rate and minimum gate voltage (VMIN) |
| VSENSE | Discharge enable sense input | Monitors panel supply decay; comparator disables gate shaping and triggers DISCHARGE when < 1.5 V |
| VGH1, VGH2, VGL, GND | Power supply terminals | VGH1 powers channels 1–7; VGH2 powers channels 8–9; VGL common negative rail; GND reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual-group 7+2 channel architecture | Enables independent biasing of main gate lines (CLK1–CLK6, VST) and auxiliary signals (START, ODD, EVEN) without cross-coupling |
| Programmable gate voltage shaping | Reduces image sticking in high-resolution LCDs by dynamically modulating gate-on voltage using FLKx and RE resistor network |
| Integrated panel discharge function | Eliminates need for external discharge circuitry by activating DISCHARGE output automatically when VSENSE falls below 1.5 V |
| Multi-flicker clock support | Accepts one, two, or three independent FLK inputs-enabling flexible timing configurations for 4-phase (FLK1/FLK2) and 6-phase (FLK1/FLK2/FLK3) systems |
| Low-impedance output stage | Delivers >500 mA peak current with <0.4 V output drop at 10 mA load-ensuring stable gate drive under heavy capacitive loading |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD gate driver level shifter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65193RHDR | Same 28-pin QFN package and pinout; adds internal VGL charge pump and supports higher VGH up to +42 V | Better suited for next-gen 8K panels requiring extended voltage headroom and reduced external component count | Select TPS65193RHDR when VGH > 38 V or VGL regulation without external DC/DC is required |
| BD8153FVM-CE2 | 8-channel device in 32-pin QFN; lacks DISCHARGE/VSENSE function but offers integrated LDOs and I²C configuration | Targeted at cost-sensitive consumer monitors where programmability outweighs panel discharge safety requirements | Choose BD8153FVM-CE2 only if system-level discharge is handled externally and I²C-based timing calibration is needed |
Compared with TPS65192RHDR, TPS65193RHDR extends voltage capability and simplifies power tree design, while BD8153FVM-CE2 trades panel safety features for configurability-neither is pin-compatible, and both require PCB layout revision and firmware adaptation.

FAQ
What is the maximum allowable VGH1 voltage for TPS65192RHDR?
The absolute maximum VGH1 rating for TPS65192RHDR is +45 V, but the recommended operating range is +12 V to +38 V. Operating above +38 V risks exceeding safe SOA limits under peak current conditions and may reduce long-term reliability. TI specifies +30 V typical operation for optimal gate shaping linearity and thermal margin.
How does the TPS65192RHDR implement gate voltage shaping on channels 1–6?
The TPS65192RHDR applies gate voltage shaping by turning off the high-side MOSFET (Q1) and activating the discharge path (Q3) on the falling edge of FLKx signals, allowing the external RE resistor network to control the decay rate and minimum voltage (VMIN). This occurs only when VSENSE ≥ 1.5 V and is synchronized to valid clock waveform segments (last 60° in 6-phase systems).
Can TPS65192RHDR drive both 4-phase and 6-phase LCD timing architectures?
Yes, TPS65192RHDR supports both 4-phase and 6-phase configurations. For 6-phase, FLK1–FLK3 connect to three independent flicker clocks; for 4-phase, FLK1 and FLK2 drive phases 1/3 and 2/4 respectively, with FLK3 grounded. Channel mapping (IN1–IN6 → CLK1–CLK6, IN7 → VST, IN8/IN9 → START/ODD/EVEN) remains consistent across both modes.
What is the role of the VSENSE pin in TPS65192RHDR operation?
The VSENSE pin in TPS65192RHDR monitors panel supply decay during power-down. When VSENSE falls below 1.5 V (with 40 mV hysteresis), it disables gate voltage shaping and triggers the DISCHARGE output to track VGH1, actively discharging the panel. During normal operation (VSENSE > 1.5 V), DISCHARGE remains at VGL and gate shaping remains enabled.
Is thermal management critical for TPS65192RHDR in high-current applications?
Yes-TPS65192RHDR can dissipate up to 3.57 W at TA = 25°C, requiring proper thermal vias under the exposed die pad connected to a VGL copper plane. TI recommends five 0.3 mm vias spaced at 1 mm intervals, with full circumferential plating and no solder mask coverage, to maintain junction temperature below 125°C under sustained 500 mA peak loads.
