STP16CPS05 Low voltage 16-bit constant current LED sink driver with auto power saving Datasheet - production data 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 5 mA to 100 mA 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 40 ns (typ.), thus improving the system Features performance. The LEDs brightness can be controlled by using an external resistor to adjust Low voltage power supply down to 3 V the STP16CPS05 output current. The 16 constant current output channels STP16CPS05 guarantees a 20 V output driving Adjustable output current through external capability, allowing users to connect more LEDs resistor in series. The high clock frequency, 30 MHz, Serial data IN/parallel data OUT makes the device suitable for high data rate Auto power-saving feature minimizes the transmission. The 3.3 V voltage supply is useful quiescent current if no active data is in applications that interface with a 3.3 V detected on the latches microcontroller. Can be driven by a 3.3 V microcontroller Output current: 5-100 mA Max clock frequency 30 MHz ESD protection: 2 kV HBM, 200 V MM Table 1: Device summary Order code Package Packing STP16CPS05MTR SO-24 1000 parts per reel STP16CPS05TTR TSSOP24 2500 parts per reel STP16CPS05XTTR TSSOP24 exposed pad 2500 parts per reel STP16CPS05PTR QSOP-24 2500 parts per reel March 2017 DocID12569 Rev 8 1/31 www.st.com This is information on a product in full production.
