Microchip Technology MCP73832T-2DCI/MC Battery Charger IC

The MCP73832T-2DCI/MC from Microchip Technology is a highly efficient, single-cell, fully integrated lithium-ion/lithium-polymer charge management controller. Designed to operate with a limited number of external components, this miniature IC offers a compact charging solution for portable electronics where space and simplicity are of the essence.

Key Features:

• Charge Management: The device provides a constant current/constant voltage charge algorithm with selectable preconditioning and charge termination. The preconditioning feature revives deeply depleted cells, while the charge termination ensures a full charge without overcharging the battery.
• Programmable Charge Current: Users can set the desired charge rate with a single external resistor, providing design flexibility to accommodate various battery sizes and desired charge times.
• High Accuracy: The MCP73832T-2DCI/MC maintains tight regulation on the final float voltage, with a precision of ±0.5%, which is crucial for maximizing battery capacity and life.
• Thermal Regulation: To protect against overheating, the IC features an internal thermal regulation mechanism that reduces the charge current under high temperature conditions.
• Status Indication: An on-chip status indicator outputs a signal that can be used to drive an external LED, providing visual feedback for power good, charging, and charge completion.
• Low Dropout Voltage: The device operates with a low dropout voltage, which enhances efficiency and allows for longer run times.
• Small Form Factor: Housed in a tiny 5-pin SOT-23 package, the MCP73832T-2DCI/MC is ideal for space-constrained applications.
