TEXAS INSTRUMENTS
The TLC5917IDR is a 8-bit constant-current LED Sink Driver designed to works alone or cascaded. Since each output is independently controlled, they can be programmed to be on or off by the user. The high LED voltage (VLED) allows for the use of a single LED per output or multiple LEDs on a single string. With independently controlled outputs supplied with constant current, the LEDs can be combined in parallel to create higher currents on a single string. The constant sink current for all channels is set through a single external resistor. This allows different LED drivers in the same application to sink various currents which provides optional implementation of multi-colour LEDs. An additional advantage of the independent outputs is the ability to leave unused channels floating. The flexibility of the TLC591x LED driver is ideal for applications such as (but not limited to) 7-segment displays, scrolling single colour displays, gaming machines, video billboards and video panels. 8 Constant-current output channels Output current adjusted through single external resistor Constant output current invariant to load voltage change Open load, short load and over-temperature detection 256-Step programmable global current gain Fast response of output current Schmitt-trigger input Thermal shutdown for over-temperature protection 20V Maximum LED voltage Green product and no Sb/Br Device Topology: Constant Current No. of Outputs: 8Outputs Output Current: 120mA Output Voltage: 17V Driver Case Style: SOIC No. of Pins: 16Pins Input Voltage Min: 3V Input Voltage Max: 5.5V Switching Frequency: 30MHz Operating Temperature Min: -40°C Operating Temperature Max: 125°C Packaging: Tape & Reel Product Range: - Automotive Qualifications Standard: - Dimming Control Type: Analogue MSL: MSL 1 - Unlimited Input Voltage: 3V to 5.5V LED Driver Application: Display, Lighting SVHC: No SVHC (15-Jun-2015) Find similar products grouped by common attribute
