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 Dtype 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
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 TSSOP16
exposed pad packages.
