It features a 16-bit (65,536 levels) PWM grayscale control for each channel, enabling smooth and accurate brightness adjustments. The device operates from a supply voltage of 3.0V to 5.5V and provides a constant current range of 0.5mA to 35mA per channel, set via an external resistor. The TLC5971RGER is housed in a compact 24-pin VQFN (4x4mm) package, making it suitable for space-constrained designs. It supports a serial interface (SDI, SCLK) for data input and can be cascaded for multiple device control. The device also includes thermal shutdown and error detection features for reliable operation.\u003c\/p\u003e\u003ch2\u003eDetailed Technical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePWM Resolution\u003c\/td\u003e\n\u003ctd\u003e16-bit (65,536 steps)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstant Current per Channel\u003c\/td\u003e\n\u003ctd\u003e0.5 mA to 35 mA (set by external resistor)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage (VCC)\u003c\/td\u003e\n\u003ctd\u003e3.0 V to 5.5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage (VOUT)\u003c\/td\u003e\n\u003ctd\u003eUp to 17 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Interface\u003c\/td\u003e\n\u003ctd\u003eSerial (SDI, SCLK)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e24-VQFN (4x4 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40°C to +85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermal Shutdown\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eError Detection\u003c\/td\u003e\n\u003ctd\u003eOpen\/Short LED detection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e12 constant-current sink channels with 16-bit PWM grayscale control\u003c\/li\u003e\n\u003cli\u003eAdjustable constant current from 0.5 mA to 35 mA per channel\u003c\/li\u003e\n\u003cli\u003eWide supply voltage range: 3.0 V to 5.5 V\u003c\/li\u003e\n\u003cli\u003eSerial interface with daisy-chain capability for multiple devices\u003c\/li\u003e\n\u003cli\u003eBuilt-in thermal shutdown and LED error detection (open\/short)\u003c\/li\u003e\n\u003cli\u003eCompact 24-VQFN (4x4 mm) package for space-saving designs\u003c\/li\u003e\n\u003cli\u003eLow power consumption and high efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTarget Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e5G base station status indicators and backlighting\u003c\/li\u003e\n\u003cli\u003eAutomotive dashboard and infotainment display backlighting\u003c\/li\u003e\n\u003cli\u003eIndustrial control panel LED indicators\u003c\/li\u003e\n\u003cli\u003eSmart home lighting systems (e.g., RGB LED strips)\u003c\/li\u003e\n\u003cli\u003ePortable electronics (e.g., smartphone notification LEDs)\u003c\/li\u003e\n\u003cli\u003eLED signage and video walls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 style=\"border-bottom:2px solid #eee; padding-bottom:10px; margin-top:40px;\"\u003e\n  Global Supply Chain \u0026amp; Wholesale Solutions\n\u003c\/h2\u003e\n\u003cp\u003eAt Jasin Chip, we provide professional supply chain and wholesale solutions for\n\u003cstrong\u003eTLC5971RGER\u003c\/strong\u003e.
