LED照明驱动器 TLC6C5912 12-Channel Shift-Register LED Driver 20-TSSOP -40 to 105
The TLC6C5912 is a monolithic, medium-voltage, low-current power 12-bit shift register designed for use in systems that require relatively moderate load power, such as LEDs.
This device contains a 12-bit serial-in, parallel-out shift register that feeds a 12-bit D-type storage register. Data transfers through both the shift and storage registers on the rising edge of the shift-register clock SRCK and the register clock RCK, respectively. The storage register transfers data to the output buffer when shift register clear CLR is high. A low on CLR clears all registers in the device. Holding the output enable G high holds all data in the output buffers low, and all drain outputs are off. Holding G low makes data from the storage register transparent to the output buffers.
This device contains a 12-bit serial-in, parallel-out shift register that feeds a 12-bit D-type storage register. Separate clocks are provided for both the shift and storage registers.
Outputs are low-side, open-drain DMOS transistors with output ratings of 40 V and 50-mA continuous sink-current OR 200-mA PWM current with single-pulse duration less than 1 ms and average current less than 50 mA capabilities when VCC = 5 V. The device contains built-in thermal shutdown protection and provides up to 2000 V of ESD protection when tested using the human-body model and the 200-V machine model.
The TLC6C5912 characterization is for operation over the ambient temperature range of −40°C to 105°C.
