MCP73871T-2CAI/ML Datasheet/PDFMCP73871T-2CAI/ML Application Field and Working Principle
MCP73871T-2CAI/ML is a series of highly efficient, cost-effective linear-mode battery chargers, which are offered as either stand-alone devices for use with a single cell lithium-ion/lithium-polymer battery or as application specific solutions with multiple device integration. This charger is designed to charge and control single cell lithium-ion/lithium-polymer battery packs. The battery pack’s cells must use the two-wire configuration and must use any voltage of 3, 3.3 or 5V. The MCP73871T-2CAI/ML is suitable for use in applications such as medical equipment, portable electronics, and notebook/PC battery packs. It can be used in many other similar products where cost and space are critical.
Working Principle
The MCP73871T-2CAI/ML is a linear-mode lithium-ion/lithium-polymer battery charger. It is a highly efficient, cost-effective solution for use in applications that require charging a single cell lithium-ion/lithium-polymer battery. It is offered in a variety of package types for use with either a single cell or application specific solutions with multiple device integration. The basic design of the charger is based on a current controlling, constant voltage charging profile. The input voltage is regulated to a precise voltage level, which is then regulated and carefully monitored by the controller. During charging, the controller continuously monitors the charge current and adjusts the charge current to the set point. When the voltage reaches the set point, the charging will terminate.In addition to protecting the battery from overcharging, the controller also has a number of features including thermal protection and short circuit protection. The thermal protection monitors the temperature of the device and will suspend or terminate charging if the temperature exceeds the set point. The short circuit protection will prevent the charge current from exceeding a certain limit, thus preventing the device from damaging itself and the battery.
Applications
The MCP73871T-2CAI/ML can be used for a variety of applications including medical equipment, portable electronics, and notebook/PC battery packs. It can be used in many other similar products where cost and space are critical.The MCP73871T-2CAI/ML is suitable for use in applications where a reliable, cost-effective and space-efficient charging solution is required.
