New design methods and components bring high
intelligence to battery charger and power-management
applications. When developing intelligent power
management systems, very complex and cumbersome
analog-only solutions are now old school. When com-
bining low-cost microcontroller’s with analog-attach,
high-speed Pulse Width Modulators (PWMs), the ben-
efits of a mixed signal design can be realized. In the
past, a complex power-management system was
developed using a high-speed analog PWM combined
with logic and specialty analog-only circuits. In some
cases, non-flexible, off-the-shelf solutions are available
for a price. For most applications, they have neither the
features, nor the capability, to meet any special
requirements. With the addition of a microcontroller, the
new design method can adapt to almost any system
command, environmental conditions or system-level
fault. AN960
