8 channel led driver shift register


















8-channel constant current LED driver with output error detection 7. Functional description The PCA is an 8-channel constant current LED driver with built-in LED output error detection. The PCA contains an 8-bit shift register and data latches, which convert serial input data into parallel output data. voltage, low-current power 8-bit shift register designed for use in systems that require relatively moderate load power, such as LEDs. This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Separate clocks are provided for both the shift and storage register. Outputs are low-side, open-. The CAT is an 8 channel constant current driver for LED billboard and other general display applications. LED channel currents are programmed together via an external RSET resistor. Low output voltage operation on the LED channels as low as V (for 2 to mA LED current) allows for more power efficient www.doorway.ru: LED Driver, 8-channel, Constant Current.


8-channel constant current LED driver with output error detection 7. Functional description The PCA is an 8-channel constant current LED driver with built-in LED output error detection. The PCA contains an 8-bit shift register and data latches, which convert serial input data into parallel output data. The TLC is an LED driver incorporating a channel shift register, data latch, and constant current circuitry with current value control and 8-channel common driver into a single chip. The constant output current is capable of 30 mA for 16 bits simultaneously, and the current value can be set by one external register. Shift register clear, active-low: CLR is the signal used to clear all the registers. The storage register transfers data to the output buffer when shift register clear CLR is high. Driving CLR is low clears all the registers in the device. DRAIN0 3 O Open-drain output: DRAIN0 to DRAIN11 are the LED current-sink channels. These pins.


Best I came up with is a 8-channel Shift register driving p-mosfets on the high-side and an 8-channel LED driver on the low-side. Is this advisable or even. Driving CLR low clears all the registers in the device. DRAIN0. 3. O. Open-drain output, LED current-sink channel, connect to LED cathode. DRAIN1. LE. Latch-Enable Input. Data is loaded transparently from the internal shift register(s) to the output latch(es) while LE is high. Data is latched into.
