Frequently Asked Questions
What charge current can the MCP73832T-2ATI/OT deliver, and how is it set?
The MCP73832T-2ATI/OT delivers a maximum charge current of 500 mA, programmed by a single external resistor connected to the PROG pin. Selecting a 2 kΩ resistor sets full 500 mA current, while higher values reduce the current proportionally, giving designers precise control over charge rate.
At what temperature does the MCP73832T-2ATI/OT activate its thermal shutdown, and why does that matter for compact PCBs?
Thermal shutdown activates at 150°C junction temperature, automatically pausing charging until the die cools, then resuming without host intervention. This protects both the IC and the battery when the 5-pin SOT-23 package is placed in confined enclosures with limited airflow, preventing damage at up to 500 mA continuous operation.
Which USB-powered portable products benefit most from the MCP73832T-2ATI/OT compared with a larger charger IC?
Products such as Bluetooth earbuds, fitness bands, and handheld medical probes benefit because the 5-pin SOT-23 footprint occupies under 10 mm² of PCB area while still providing 4.2 V regulation and 500 mA rate, eliminating the need for a larger 8-pin SOIC charger and cutting bill-of-materials cost for single-cell designs.
How does the MCP73832T-2ATI/OT STAT pin simplify charge status reporting in a 3.3 V system?
The open-drain STAT pin can be pulled up to 3.3 V through a resistor and drives a LED or an MCU GPIO low during active charging, turning high-impedance when charging is complete or no battery is present. This requires only 1 passive component and works across the 3.75 V to 6 V input range of the device.
