An advanced energy management and charge control device, the MCP73832T-2DCI/OT series is a Microchip Technology-designed system specifically made for single-cell Li-Ion and Li-polymer battery charging. This extremely versatile and efficient content allows for charging devices up to four cells, designed for numerous applications, such as portable equipment, hand-helds, and digital cameras.

The device offers controlled current battery charging by precise control over the charge current, charge voltage and recharge cycles, long-term battery maintenance. It provides a full-featured system with fast charge programming capabilities and very precise charge control, allowing works better with fast-rate battery charging.

The core of the MCP73832T-2DCI/OT is a microcontroller in which the information temperature, voltage and current inputs are delivered to the system. It provides precise control of charge current, charge voltage, and recharge cycles to maximize the life of the battery. The main feature of this chip is the ability to detect a low-voltage battery and adjust for optimal charging, depending on the battery\'s condition.

The MCP73832T-2DCI/OT can accept input from a wide range of sources, such as wall adapters, USB ports, solar cells, and PC power supplies. Generally, the power source is regulated by the device\'s PowerPath control, or by user-defined input settings. In addition, the device includes short-circuit protection, overvoltage protection and timer-controlled charge cycles.

The actual charging process is based on three distinct stages: pre-charge, fast-charge and maintenance. The pre-charge stage drives a low amount of current into the battery, allowing it to adapt to a higher charging level and ensuring safety. The fast-charge stage, as its name suggests, rapidly increases the volume of current, continuing until the voltage reaches the set charge voltage. The maintenance stage consists of a trickle charge cycle, in which a very small current is applied to the battery.

The MCP73832T-2DCI/OT series is a reliable, low-cost battery charger, providing intelligent, safe and efficient charge control. It can achieve fast battery charging, while protecting the battery and optimizing its life. It is ideal for battery-powered applications such as portable equipment, hand-helds, and digital cameras.
