STP04CM05
4-bit constant current power-LED sink driver
Features

4 constant current output channels Adjustable output current through one external resistor Can be driven by a 3.3 V microcontroller Serial data IN/parallel data OUT Output current: 80-400 mA 20 V of output driving capability 30 MHz clock frequency UVLO (under voltage lockout) and POR (power ON reset) 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. 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 DIP-14, SO-14 and TSSOP16 exposed pad packages.
TSSOP16 (Exposed pad) Dip-14 SO-14
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. Table 1. Device summary

Maximum rating
Stressing the device above the rating listed in the "absolute maximum ratings" table may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents. Table 3.

The latches circuit holds data when the LE terminal is low. When the LE terminal is at a high level, the latch circuit holds the data it passes from the input to the output. When the OE terminal is at a low level, the output terminals OUT0 to OUT3 respond to the data, either ON or OFF. When the OE terminal is at a high level, it switches off all the data on the output terminal.
