STP16DPP05:Low voltage 16-bit constant current LED sink driver with output error detection
The STP16DPP05 is a monolithic, low voltage, low current power 16-bit shift register
designed for LED panel displays. The device features a 16-bit serial-in, parallel-out
shift register that feeds a 16- bit D-type storage register. In the output stage,
sixteen regulated current sources are designed to provide 3 to 40 mA of constant current
to drive the LEDs. The STP16DPP05 features open and short LED detection on the outputs.
The detection circuit checks for 3 different conditions that can occur on the output
line: short to GND, short to VO or open line. The data detection results are
loaded in the shift registers and shifted out via the serial line output. The detection
functionality is implemented without increasing the pin count, through a secondary
function of the output enable and latch pin (DM1 and DM2 respectively). A dedicated
logic sequence allows the device to enter or exit from detection mode. The STP16DPP05
output current can be adjusted through an external resistor to control the light
intensity of the LEDs. LED brightness is adjustable from 0% to 100% via the
OE/DM2 pin. The STP16DPP05 guarantees a 20 V output driving
capability, allowing users to connect more LEDs in series. The high 30 MHz clock
frequency makes the device suitable for high data rate transmission. The 3.3 V supply is
well suited for applications which interface a 3.3 V MCU. Compared to a standard TSSOP
package, the TSSOP with exposed pad increases heat dissipation capability by a factor of
2.5.
