Each channel can be turned on or off by – Channel-to-Channel = ±1% (typ) writing data to an internal register. The constant – Device-to-Device = ±2% (typ) current value of all 16 channels is set by a single • Data Transfer Rate: 33 MHz external resistor with 128 steps for the global brightness control (BC). • BLANK Pulse Width: 40 ns (min) • LED Open Detection (LOD)/LED Short The TLC5929 has six error flags: LED open detection Detection (LSD) with Invisible Detection Mode (LOD), LED short detection (LSD), output leakage (IDM) detection (OLD), reference current terminal short detection (ISF), pre-thermal warning (PTW) and • Output Leakage Detection (OLD) Detects 3 µA thermal error flag (TEF). In addition, the LOD and Leak LSD functions have invisible detection mode (IDM) • Pre-Thermal Warning (PTW) that can detect those errors even when the output is off. The error detection results can be read via a • Thermal Shutdown (TSD) serial interface port. • Current Reference Terminal Short Flag (ISF) The TLC5929 also has a power-save mode that sets • Power-Save Mode with 10- µA Consumption the total current consumption to 10 µA (typ) when all • Undervoltage Lockout Sets the Default Data outputs are off.
