NXP NPIC shift
register based LED
drivers
High-voltage serial-in, parallel-out shift
register devices
Designed for I/O expansion, these shift register based LED drivers allow the use of lower
pin-count (and lower-cost) controllers. Serial outputs support cascading, so just three controller
I/Os can control the states of 16, 24 or more LEDs.

The NXP NPIC family of shift register based LED drivers
integrates the MOSFET drivers used in traditional low-power
shift register applications. This integration greatly reduces the
component count, layout complexity, and footprint of LED
driving applications.
Integrated voltage clamps in the outputs provide protection
against inductive transients. This protection makes the NPIC
devices suitable for power driver applications such as relay,
solenoids, and other low-current, medium-voltage loads.
8-bit and 12-bit shift registers are available in the NPIC family.
These are made available in the industry’s standard and
smallest packages.
INHERENT PROTECTION FEATURES
The open-drain outputs include circuitry that limits the maximum current each output can sink. As the drain voltage increases,
the drain source current decreases. This feature protects the outputs and the components they are driving. At 25 °C, the output
clamp is typically activated when the drain source current is 250 mA.
Thermal protection is also included in the open-drain outputs. As the temperature increases, so does the output resistance. This
limits drain source current and prevents damage to the output and the components it is driving. At 25°C, the output typically
limits the drain source current to 120 mA.

NPIC devices are available in industry standard SO and TSSOP
packages, as well as the innovative leadless DQFN packages.
The smaller footprint leadless DQFN provides a 76% footprint
reduction compared to TSSOP. This enables NPIC solutions to
