STP04CM05 4-bit constant current power-LED sink driver Features 4 constant current output channels Adjustable output current through one external resistor TSSOP16 Can be driven by a 3.3 V microcontroller SO-14 (Exposed pad) Serial data IN/parallel data OUT Output current: 80-400 mA Description 20 V of output driving capability 30 MHz clock frequency The STP04CM05 is a high-power LED driver and 4-bit shift register designed for Power-LED UVLO (under voltage lockout) and applications. POR (power ON reset) TSD, thermal shutdown, output off when The STP04CM05 contains a 4-bit serial IN, junction temperature exceeds limit parallel OUT shift register that feeds a 4-bit D-type storage register. In the output stage, four Operating free-air temperature range -40 to regulated current sources were designed to 125 C provide 80-400 mA constant current to drive high ESD protection 2.5 kV HBM, 200 V MM power LEDs. Available in high thermal TSSOP exposed pad. The STP04CM05 guarantees 20 V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30 MHz, also satisfies the system requirements which include high volume data transmission. The STP04CM05 is well suited for very high brightness displays and special lighting applications. The STP04CM05 is offered in SO-14 and TSSOP16 exposed pad packages. Table 1.
