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
SO-14
Dip-14
■ 20 V of output driving capability
■ 30 MHz clock frequency
TSSOP16
(Exposed pad)
■ 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 ºC
■ 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.
Description
The STP04CM05 is a high-power LED driver and
4-bit shift register designed for Power-LED
applications.
The STP04CM05 is well suited for very high
brightness displays and special lighting
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.
The STP04CM05 is offered in DIP-14, SO-14 and
TSSOP16 exposed pad packages.

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.
