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. KEY FEATURES ` 33 V, 100 mA open-drain outputs ` Simple control interface ` 5.0 and 3.3 V supply options ` Cascadable ` Overvoltage-tolerant inputs ` Inherent current limiting and thermal protection ` Integrated voltage clamps ` Fully specified (-40 to +125 °C) ` AEC-Q100 options ` Pb-free, RoHS-compliant and Dark Green KEY BENEFITS ` Reduced component count and footprint ` Self-protecting outputs (overcurrent) ` Suitable for driving inductive loads ` Low power consumption APPLICATIONS ` GPIO expansion ` LED drivers ` Displays ` Industrial ` Automotive 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.
