To resolve this caterpillar issue caused by an open LED, the TLC59581/82 device has an enhanced circuit for caterpillar canceling, thermal shut down (TSD) and IREF resistor short protection (ISP), which ensures a higher system reliability. The TLC59581/82 device also has a power-save mode that sets the total current consumption to 0.8 mA (typical) when all outputs are off. The TLC59581/82 device is a good solution to improve display performance of a multiplexing panel for low-grayscale patterns. 6 Pin Configuration and Functions RTQ Package with Thermal Pad 56-Pin VQFN (Top View) Pin Functions PIN I/O DESCRIPTION NAME NO. Grayscale(GS) pulse width modulation (PWM) reference clock control for OUTXn. GCLK 29 I Each GCLK rising edge increase the GS counter by 1 for PWM control. GND ThermalPad – Power ground. The thermal pad must be soldered to GND on PCB. Maximum constant-current value setting. The OUTR0 to OUTB15 maximum constant output current are set to the desired values by connecting an external resistor between IREF and IREF 1 – IREFGND. See (1) for more detail. The external resistor should be placed close to the device. Analog ground. Dedicated ground pin for the external IREF resistor. This pin should be IREFGND 56 – connected to analog ground trace which is connected to power ground near the common GND point of board. (1) The deviation of each output in same color group (OUTR0~15 or OUTG0~15 or OUTB0~15) from the average of same color group constant current. The deviation is calculated by the formula. (X = R or G or B, n = 0~15) spacer Copyright © 2015, Texas Instruments Incorporated Submit Documentation Feedback 3 TLC59582 |
