STP16CPS05
Product Page
ST’s recently introduced Power Logic family has now been enhanced
by the addition of the STP16CPS05 series. These 16-bit LED drivers
are the first on the market to include auto-power-saving features,
allowing manufacturers to meet the high power efficiency requirements
of industrial lighting, signage and transport applications with
an energy saving of around 80 % compared to the standard solution.

An evolutionary advantage over the previous STP16Cx596 Power Logic
series, the new constant current LED drivers allow individual ICs
to go into shutdown mode when no active inputs are detected.
As a result, STP16CPS05 can save power without any external intervention,
making it the ideal solution to support the numerous worldwide energy-saving
programs.

The STP16CPS05 Power Logic series features a clock and data re-synchronization
function, which is useful when the devices are connected in cascade.
STP16CPS05 can work with a power supply from 3.3 V up to 5 V; their
output current is programmable from 5 mA to 100 mA to suit applications
requiring mid-current range. This high-precision LED control guarantees
the industry’s best output precision of ±1.5 % Bit-to-Bit
and ±5 % Chip-to-Chip over the output current range from
20 mA to 100 mA, and covers the full wide temperature range of -40
°C to +125 °C.
The ICs also have the market’s highest Vout of 20 V. When
it comes to protection, these ICs are ESD protected at 2.5 kV(HBM)
and 200 V(MM), and in addition are thermally-protected by in-built
automatic thermal-shutdown circuitry.
The STP16CPS05 series are available in three package types, one
of which, the thermally efficient exposed-pad TSSOP, comes with
outstanding heat dissipation features of RthJC = 37.5 °C/W.
