STP04CM05 4-bit constant current power-LED sink driver Datasheet - production data Description The STP04CM05 is a high-power LED driver and 4-bit shift register designed for Power-LED applications. The STP04CM05 contains a 4-bit serial IN, parallel OUT shift register that feeds a 4-bit D- type storage register. In the output stage, four regulated current sources were designed to provide 80-400 mA constant current to drive high power LEDs. Features The STP04CM05 guarantees 20 V output driving 4 constant current output channels capability, allowing users to connect more LEDs Adjustable output current through one in series. The high clock frequency, 30 MHz, also external resistor satisfies the system requirements which include Can be driven by a 3.3 V microcontroller high volume data transmission. Serial data IN/parallel data OUT The STP04CM05 is well suited for very high Output current: 80-400 mA brightness displays and special lighting 20 V of output driving capability applications. 30 MHz clock frequency UVLO (under voltage lockout) and POR The STP04CM05 is offered in TSSOP16 (power ON reset) exposed pad packages. TSD, thermal shutdown, output off when junction temperature exceeds limit Operating free-air temperature range -40 to 125 C ESD protection 2.5 kV HBM, 200 V MM Available in high thermal TSSOP exposed pad Table 1: Device summary Order code Package Packing STP04CM05XTTR TSSOP16 exposed pad (tape and reel) 2500 parts per reel January 2016 DocID14191 Rev 6 1/22 www.st.com This is information on a product in full production.
