Product Description

description
The TLC5921 is a current-sink constant current driver incorporating shift register and data latch. The current value at constant current output can be set by one external register. The device also incorporates thermal shutdown (TSD) circuitry which turns constant current output off when the junction temperature exceeds the limit, and LED open detection (LOD) circuitry to report the LED was disconnected.
Drive Capability and Output Counts
– 80 mA (Current Sink) x 16 Bits
Constant Current Output Range
– 1 to 80 mA (Current Value Setting for All Output Terminals Using External Resistor)
Constant Current Accuracy
– ±1% (Typ)
– ±4% (Max) (Maximum Error Between Bits, All Bits On)
Voltage Applied to Constant Current Output Terminal
– Minimum 0.6 V (Output Current 40 mA)
– Minimum 1 V (Output Current 80 mA)
Data Input
– Clock Synchronized 1 Bit Serial Input
Data Output
– Clock Synchronized 1 bit Serial Output (With Timing Selection)
