The LP5523TM/NOPB device is a versatile, programmable light engine for use in standard systems in the PMIC - LED Drivers application field. The device provides a high degree of flexibility to lighting designers and can be used to control strings of LEDs, or multiplexed arrays of LEDs, with up to twelve total output channels. With its simple and intuitive programming interface, this device can easily be incorporated into existing products, speeding time to market and reducing development time and cost.

The LP5523TM/NOPB can be used to drive multicolor LED arrays, with individual LEDs operating as low as 20 mA per channel in setup mode. In operation, the LED output current can be programmed up to 60 mA per channel. When driving LED strings, the current per LED is limited to the maximum channel capacity.

The LP5523TM/NOPB device includes a full-featured logic circuit to control on/off of LED strings and color mixing. The preprogrammed logic gates can be used to control LED strings and groups based on a combination of control input and direct control. The device also includes an integrated serial data receiver and associated logic circuit, enabling logic control from any device with an 8-bit Microcontroller or PWM (pulse-width modulation) output.

In addition to driving LED strings, the LP5523TM/NOPB can be used to control switches and test points, providing a convenient and cost effective way to add more control capability to the board. The integrated logic circuit can be used to perform a wide variety of digital control functions, such as setting up dimming or drive resistance values. The LP5523TM/NOPB also offers a configurable internal delay system which allows the user to configure the device to switch on or off at predetermined intervals.

The LP5523TM/NOPB provides a variety of options for direct control of individual channels. The direct control feature provides efficient control of each channel independently, allowing the user to create complex lighting effects, such as color mixing, fading, blinking and flashing.

The LP5523TM/NOPB includes an internal oscillator, allowing the device to run independently from an external clock source. The internal oscillator provides clock synchronization to the logic circuit, allowing the user to create lighting sequences without the need for an external clock. Additionally, a programmable PWM waveform generator is included, providing a convenient way to create lighting effects.

The LP5523TM/NOPB is compatible with various analog and digital control interfaces such as I2C and SPI. Additionally, it can be connected to the board interconnect through a board controller, providing a simple and efficient way of connecting the device to the board. In addition, the device supports multiple levels of fault protection, helping to ensure that the device will always operate reliably.

The LP5523TM/NOPB is a flexible and easy-to-use LED driver designed to be used in a wide variety of applications. It is ideal for LED lighting designs that require maximum flexibility and is perfect for creating complex multi-color designs. With its broad range of features, the LP5523TM/NOPB is the ideal solution for a variety of LED applications.
