Microchip Technology MCP73833T-FCI/MF Charge Management Controller

The MCP73833T-FCI/MF is an advanced linear charge management controller for highly integrated and space-constrained applications. Manufactured by Microchip Technology, a leader in microcontroller, mixed-signal, analog, and Flash-IP solutions, this device is designed to provide reliable charging for single-cell Lithium-Ion (Li-Ion) or Lithium-Polymer (Li-Poly) batteries.

Featuring an input voltage range of 4.5V to 6.0V, the MCP73833T-FCI/MF allows for flexible power sourcing from USB ports and AC-DC wall adapters. Its compact design is encapsulated in a 10-DFN (3x3) package, making it ideal for portable applications where space is at a premium.

Key Features:

• Integrated pass transistor, current sense, and reverse discharge protection.
• Programmable charge current from 15mA to 500mA.
• Preconditioning of deeply depleted cells at reduced current.
• Automatic recharge feature.
• Charge status outputs that can directly drive LEDs.
• Thermal regulation to maximize charge rate without risk of overheating.
• Under-voltage lockout (UVLO).
• Automatic power-down when input voltage is removed.

The MCP73833T-FCI/MF integrates a host of safety features that ensure the battery is charged efficiently and safely. The device provides constant current/constant voltage operation with thermal regulation to safely charge the battery to its full capacity. Its preconditioning feature revives overly discharged cells, and an automatic recharge function keeps the battery topped up when necessary.

This charge management controller is well-suited for a variety of applications, including but not limited to personal data assistants (PDAs), cellular phones, digital cameras, MP3 players, Bluetooth headsets, and USB chargers. With its comprehensive feature set and compact form factor, the MCP73833T-FCI/MF is an excellent choice for designers looking to incorporate a reliable and efficient charging solution into their battery-powered devices.
