Product details
Overview
TLC69602QPWPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive LED driver IC for LCD local dimming backlight systems, integrating 16 precision constant-current sinks (30mA/20V), 15-bit brightness resolution, adaptive headroom voltage control (AHVC), and daisy-chain UART/INT diagnostics - deployed in central infotainment displays requiring high-contrast, low-power, fault-aware dimming.
For engineers reviewing the TLC69602QPWPRQ1 datasheet, TLC69602QPWPRQ1 pinout, TLC69602QPWPRQ1 application, or TLC69602QPWPRQ1 equivalent, key selection criteria include its 28-pin HTSSOP package with PowerPAD™ thermal pad, ±2% channel-to-channel current matching, 20MHz daisy-chain interface, and integrated LED open/short/thermal shutdown detection for functional safety–capable automotive display subsystems.
Technical Context
The TLC69602QPWPRQ1 implements time-multiplexed local dimming control with 2× multiplexing capability, enabling up to 1024 devices in daisy chain for >32,000 zones. Its SRAM-based brightness storage supports black insertion and variable refresh rate (VRR) features to enhance display quality.
It operates from 3V to 5.5V VCC, uses adaptive headroom voltage control (AHVC) to regulate external DC/DC via a single FB pin from the last device in chain, and delivers ultra-low power consumption: ≤200μA in standby and ≤3.5mA in normal mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 3V to 5.5V - compatible with standard automotive 3.3V/5V supply rails without level-shifting. |
| Output Current / Voltage | 30mA per channel, 20V compliance - supports typical automotive LED strings up to 5–6 white LEDs in series. |
| Current Matching | ±2% (typ.) channel-to-channel error - ensures uniform luminance across local dimming zones without per-channel calibration. |
| Brightness Resolution | Up to 15-bit PWM/hybrid dimming - enables smooth grayscale transitions and eliminates visible contouring in HDR displays. |
| Daisy-Chain Speed | Up to 20MHz data transfer - allows full 16-channel update latency under 10μs for real-time video frame synchronization. |
| Diagnostic Outputs | UART + INT pin or CLK_O/SOUT two-wire readback - provides flexible integration into ASIL-B diagnostic architectures. |
| Thermal Protection | Integrated thermal shutdown detection - halts output and asserts flag before junction temperature exceeds safe operating limit. |

FAQ
What is the maximum LED string voltage supported by the TLC69602QPWPRQ1?
The TLC69602QPWPRQ1 supports up to 20V compliance voltage per output channel, enabling direct drive of typical automotive white LED strings containing 5–6 series-connected LEDs at 30mA. This rating is specified under worst-case thermal conditions and remains stable across the full –40°C to +125°C operating range.
Does the TLC69602QPWPRQ1 require external current-setting resistors?
No, the TLC69602QPWPRQ1 does not require external current-setting resistors. It integrates precision internal current references and 16 matched current sinks, delivering factory-trimmed 30mA output with ±2% channel-to-channel matching - eliminating calibration components and reducing BOM count.
How does the daisy-chain interface of the TLC69602QPWPRQ1 simplify large-scale local dimming systems?
The TLC69602QPWPRQ1 uses a two-wire daisy-chain interface (CLK_I/SIN → CLK_O/SOUT) supporting up to 1024 devices. This eliminates parallel bus routing, reduces host GPIO count, and enables synchronized updates across >32,000 dimming zones using a single master clock - critical for scalable automotive display architectures.
What diagnostic capabilities does the TLC69602QPWPRQ1 provide for functional safety compliance?
The TLC69602QPWPRQ1 provides three dedicated hardware diagnostics: LED open detection (LOD), LED short detection (LSD), and thermal shutdown detection (TSD). These flags are reported either via UART register reads or active-low INT pin assertion - supporting ASIL-B diagnostic coverage without external monitoring circuitry.
Is the TLC69602QPWPRQ1 pin-compatible with other members of the TLC696x2/4/8-Q1 family?
Yes, all HTSSOP-packaged variants - including TLC69602QPWPRQ1, TLC69604QPWPRQ1, TLC69608QPWPRQ1, TLC69612QPWPRQ1, etc. - share identical 28-pin PWP footprints and pin assignments. This enables drop-in replacement for different multiplexing ratios (2×/4×/8×) or current ratings (30mA/60mA) without PCB revision.
