Modern MCUs are intentionally low power and low current. Use one of these tiny devices to gain high power open drain outputs using only a few pins. Cascading multiple stage shift register with storage permits expansion to many outputs.
Each open drain output is capable of 33V@100mA drive, with 250mA total device capability.
Short Demo Description
* The NPIC is a serial-in, parallel-out shift register with onboard power FETs. The serial interface is so simple that no microcontroller is required: this demo uses only a 555 timer to create the LED sequencing.
* Two rotary knobs are provided to allow the user to select the speed of the LED scan and the delay between scans
* Typical LED drive requires a microcontroller, many IO pins and external power FETs. The NPIC6C596 integrates a serial input, latches and Power FETS capable of up to 100mA@30V on each of the 8 output channels. It also includes onboard overcurrent protection and thermal shutdown to protect itself from overload.
* The NPIC6C596 provides the lowest-cost-per-channel solution for driving LEDs for a wide variety of consumer, industrial and automotive applications.
* Multiple NPIC6C596 can be cascaded together to drive thousands of LEDs from a single set of 3 control wires, greatly reducing wiring and connector costs in a system
* This device is available in Q100 Automotive Grade for high-temperature, high reliability applications
* The design of this demo can be used directly for customer applications such as sequencing road signs, emergency vehicle light bars, etc.
* With the addition of a microcontroller, the NPIC can create an infinite number of LED patterns, including 7-segment LED drive, graphical displays and PWM dimming
