DEVICE OVERVIEW
The MCP19114/5 are highly integrated, mixed-signal low-side synchronous controllers that operate from 4.5V to 42V. The family features an analog PWM controller with an integrated microcontroller core used for LED lighting systems, battery chargers and other low-side switch PWM applications. The devices feature an analog internal PWM controller similar to the MCP1631, and a standard PIC® microcontroller similar to the PIC12F617.
Complete customization of device operating parameters, start-up or shutdown profiles, protection levels and fault handling procedures are accomplished by setting digital registers using Microchip’s MPLAB® X Integrated Development Environment software and one of Microchip’s many in-circuit debugger and device programmers.
