com STP16CPS05 Low voltage 16-Bit constant current LED sink driver with auto power saving Preliminary Data Features ■ ■ ■ ■ ■ Low voltage power supply down to 3V 16 constant current output channels Adjustable output current through external resistor Serial Data IN/Parallel Data OUT Auto power-saving feature minimizes the quiescent current if no active data is detected on the latches Can be driven by a 3.
3V microcontroller Output current: 5-80mA 30MHz clock frequency TSSOP24 TSSOP24 (exposed pad) DIP-24 SO-24 ■ ■ ■ Description The STP16CPS05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays.
The STP16CPS05 contains 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 provide from 5mA to 80mA constant current to drive the LEDs.
The Auto Power Shut-Down and Auto Power-ON feature allows the device to save power without any external intervention.
The output current setup time is 40ns (typ), thus improving the system performance.
The LEDs' brightness can be controlled by using an external resistor to adjust the STP16CPS05 output current.
The STP16CPS05 guarantees a 20V output driving capability, allowing users to connect more LEDs in series.
The high clock frequency, 30MHz, makes the device suitable for high data rate transmission.
The 3.
3V voltage supply is useful in applications that interface with a 3.
3V microntroller.
