Charge-management Controllers

By Staff Author | December 27, 2006

Microchip Technology Inc. announces the MCP73833 and MCP73834 (MCP73833/4) single-cell, high current (1 A), Li-Ion/Li-Polymer linear charge-management controllers. These fully integrated charge-management controllers combine several key, standard charge-management and safety features in a single chip for reliable charging of high-capacity Li-Ion and Li-Polymer batteries. Available in small MSOP and thermally efficient 3 mm &#215 3 mm DFN packages, the MCP73833/4 chargers enable smarter, faster and safer battery &#151 charger designs. Because they combine a pass transistor, current-sense and reverse-discharge protection on a single chip, the MCP73833/4 charge-management controllers eliminate the need for external components and enable smaller, more integrated charging solutions. Multiple combinations of key charging parameters, including pre-conditioning current threshold and ratio, charge-termination threshold and recharge threshold ratio are available, meaning the devices provide standard product support for a variety of high-current Li-Ion/Li-Polymer battery charger applications. Additionally, with high charging currents of up to 1A and support for multiple regulated output voltages (4.2 V, 4.35 V, 4.4 V and 4.5 V), the devices can be used with early generation batteries where output voltages are lower, as well as newer batteries where output voltages are higher.
