Microchip MCP19116/7 power analog controllers

Microchip Technology has launched two digitally enhanced power analog controllers for LED lighting applications. The MCP19116 and MCP19117 are designed to increase accuracy for LED lighting and allow users to carefully control LED light output levels for long-life applications.

The MCP19117 is functionally equivalent to the MCP19116 (both mid-voltage 4.5–42 V) but offers a debugging interface and 12 GPIO as opposed to 8 GPIO. By combining the power and performance of an analog-based controller with the flexibility of a digital interface, the products offer an intelligent pulse width modulation (PWM) controller with a fully integrated 8-bit PIC MCU core. The digital interface also allows for communication and configuration, allowing a subsystem to report status or be remotely controlled. This functionality is necessary for adding lighting to many applications, including automotive and remotely accessible Internet of Things (IoT) devices.

The devices can also be programmed to respond to measurements or events within the system, dynamically tailoring the operation to the environment or intelligently responding to faults for robust operation. They are similar to their predecessors but contain additional calibration features for improved accuracy and measurement, as well as a larger flash memory for storing additional code.
