What are the key features of MCP73864-I/SL?
- Dual-channel (2-channel) linear battery charger architecture enabling simultaneous independent Li-Ion or Li-Polymer cell charging in a single 16-pin SOIC IC
- Fixed threshold charge control with no external adjustment required, simplifying firmware and reducing external component count for portable device designs
- RoHS-compliant lead-free (Pbfree Code: Yes, JESD-609 e3) SOIC-16 package with plastic/epoxy body for compliance with environmental regulations
What is MCP73864-I/SL used for?
The MCP73864-I/SL is used in portable consumer electronics such as dual-cell wireless earbuds, handheld medical devices, and compact IoT nodes where two Li-Ion or Li-Polymer cells must be charged independently from a single IC. Its linear charger architecture minimizes switching noise, making it suitable for noise-sensitive audio and measurement equipment that cannot tolerate the RF emissions of switching chargers. The 16-pin SOIC package and simple fixed-threshold design also make it accessible for hobbyist and low-volume industrial prototypes requiring multi-cell battery management without complex firmware.

Frequently Asked Questions
How many battery cells can the MCP73864-I/SL charge simultaneously, and what cell chemistry does it support?
The MCP73864-I/SL features 2 independent charge channels, allowing it to charge 2 Li-Ion or Li-Polymer cells simultaneously within a single 16-pin SOIC package. This dual-channel capability eliminates the need for two separate single-channel charger ICs in designs such as true wireless stereo earbuds and dual-battery handheld instruments, reducing BOM cost and board space.
Why would a designer choose the MCP73864-I/SL linear charger over a switching charger for a medical device?
Linear chargers like the MCP73864-I/SL generate no high-frequency switching noise because they regulate charge current through a pass transistor rather than a PWM switch. In noise-sensitive medical devices such as portable ECG monitors or hearing aids, this eliminates the need for bulky EMI filters and shields that switching chargers require, keeping the BOM lean and the analog measurement front-end free from interference artifacts at frequencies above 1 kHz.
What does the fixed threshold design of the MCP73864-I/SL mean for firmware complexity in a charger application?
The MCP73864-I/SL uses fixed (non-adjustable) charge threshold voltages, meaning the termination voltage for Li-Ion cells — typically 4.2 V — is set internally without requiring external resistor dividers or DAC outputs. This eliminates firmware-driven threshold calibration, reduces the risk of over-voltage damage from software bugs, and shortens design-to-production time for standard single-chemistry battery packs.
What package does the MCP73864-I/SL use, and what board assembly process is compatible with it?
The MCP73864-I/SL is housed in a 16-pin SOIC (Small Outline IC) package with a 0.150-inch body width and 1.27 mm pin pitch. This wide-body SOIC-16 footprint is compatible with standard SMT reflow and wave soldering processes, and its larger pad size compared to TSSOP or MSOP packages makes it more forgiving during manual rework — a practical advantage for prototype and low-volume production runs.
