1 / 25 page TCA62746AFG/AFNG 2007-05-22 1 TOSHIBA CMOS Integrated Circuit Silicon Monolithic TCA62746AFG,TCA62746AFNG 16-Output Constant Current LED Driver with Output Open/Short Detection The TCA62746 series are LED drivers with sink type constant circuit output, making them ideal for controlling LED modules and displays. The current value of the 16-output is configurable using one external resistor. In addition, these drivers are equipped with a function for detecting the output voltage when the output load LEDs open or short, and which then outputs the result as serial data. These drivers consist of a 16-constant current output block, a 16-bit shift register, a 16-bit latch and a 16-bit AND-gate. The suffix (G) appended to the part number represents a Lead (Pb)-Free product. Features • 16-output built-in • Output open detection (OOD) function : When in detection mode, outputs the detection results via SOUT. • Output short detection (OSD) function : When in detection mode, outputs the detection results via SOUT. • Output current setting range : 2 to 50 mA × 16-constant current output • Current accuracy (@ REXT = 1.56 kΩ, VO = 1.0 V, VDD = 5.0 V) : Between outputs: ± 1% (typ.) Between devices: ± 3% (typ.) • Control data format: serial-in, parallel-out • I/O logic: TTL level (Schmitt trigger input) • Data transfer frequency: fMAX = 25 MHz (max) • Power supply voltage: VDD = 4.5 to 5.5 V • Operation temperature range: Topr = −40 to 85°C • Constant current output voltage: VO = 17V (max) • Output delay circuit built-in: Internal data reset circuit for power-on resetting (POR) • Backward compatible to TB62706B and TB62726A series drivers • Package: FG type: SSOP24-P-300-1.00B FNG type: SSOP24-P-300-0.65A Caution This device is sensitive to electrostatic discharge. Please handle with care. The terminals which are marginal to electro static discharge are shown in the following table. (Please refer to page 22 for details.) ESD test MM Model Marginal terminals (MM Model Internal Standard ±200V) 5,6,7,8,9,10,11,12,13,14,15,16,19,20 * ESD test HBM Model Internal Standard (±2000V) is OK TCA62746AFG TCA62746AFNG Weight SSOP24-P-300-1.00B : 0.32 g (typ.) SSOP24-P-300-0.65A : 0.14 g (typ.) |
