STP16CPPS05 Low voltage 16-bit constant current LED sink driver with auto power-saving Preliminary data Features Low voltage power supply down to 3 V 16 constant current output channels Adjustable output current through external resistor Serial data IN/parallel data OUT Auto power-saving 3.3 V MCU-driving capability Output current: 3 to 40 mA 30 MHz clock frequency Available in high thermal efficiency TSSOP exposed pad ESD protection: 2 kV HBM, 200 V MM SO-24 TSSOP24 TSSOP24 (exposed pad) The STP16CPPS05 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 pin. The auto power-shutdown and auto power-ON feature allows the device to save power with no external intervention. Description The STP16CPPS05 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. Table 1. QSOP-24 The STP16CPPS05 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 Device summary Order codes Package Packaging STP16CPPS05MTR SO-24 1000 parts per reel STP16CPPS05TTR TSSOP24 2500 parts per reel STP16CPPS05XTTR TSSOP24 exposed pad 2500 parts per reel STP16CPPS05PTR QSOP-24 2500 parts per reel October 2009 Doc ID 16536 Rev 1 This is preliminary information on a new product now in development or undergoing evaluation.
