HELP PLEASE! MCP73861 charge Controller

[Darkest_Elitez]

Hi Guys,

A charge controller controls the voltage and current from device like solar panel so that it will not damage the battery.

From what I know, there are 3 types of charge controllers. They are the linear charge controller, PWM charge controller and the MPPT.

ok here is the questions:

1. can you guys please help me identify what kind of charge controller MCP73861 is categorized under?

2. i am thinking maybe MCP 73861 is a linear charge controller but can you guys confirm with my whether is it a series type or a shunt type or non of those.

3. is buck converter and boost converter called the PWM charge controller?

Sorry to bother all of you, I am still new in this field, therefore need the help of professionals and experienced engineers, scientist or enthusiast like all of you.

Thank you so much for helping

2. i am thinking maybe MCP 73861 is a linear charge controller but can you guys confirm with my whether is it a series type or a shunt type or non of those.

I think the purpose of a shunt function, is when you have to divert power to a load after the battery reaches full charge. An unloaded turbine will spin freely and quickly, burning out its bearings. For this reason some controllers are designed to send incoming power to a water heater, etc., when the battery is not charging.

3. is buck converter and boost converter called the PWM charge controller?

These use pulsed DC in some way.

Plain PWM might be a switch turning on and off. This is an easy method to keep charging current within safe limits, or to taper current as the battery reaches full charge.

The switched coil converters are useful for obtaining maximum power transfer. Such controllers are called MPPT type.

MCP 73861 says [and looks] it is linear, sure look series to me
