Description

1 Features 3 Description
The TLC5940 is a 16-channel, constant-current sink 1• 16 Channels
LED driver. Each channel has an individually
• 12 bit (4096 Steps) Grayscale PWM Control adjustable 4096-step grayscale PWM brightness
• Dot Correction control and a 64-step, constant-current sink (dot
– 6 bit (64 Steps) correction). The dot correction adjusts the brightness
variations between LED channels and other LED – Storable in Integrated EEPROM drivers. The dot correction data is stored in an
• Drive Capability (Constant-Current Sink) integrated EEPROM. Both grayscale control and dot
– 0 mA to 60 mA (VCC < 3.6 V) correction are accessible through a serial interface. A
single external resistor sets the maximum current
– 0 mA to 120 mA (VCC > 3.6 V) value of all 16 channels.
• LED Power Supply Voltage up to 17 V
The TLC5940 features two error information circuits. • VCC = 3 V to 5.5 V
The LED open detection (LOD) indicates a broken or
• Serial Data Interface disconnected LED at an output terminal. The thermal
• Controlled In-Rush Current error flag (TEF) indicates an overtemperature
condition. • 30 MHz Data Transfer Rate
• CMOS Level I/O Device Information(1)
• Error Information PART NUMBER PACKAGE BODY SIZE (NOM)
