Frequently Asked Questions
What is the maximum charge current the MCP73834T-FCI/UN can deliver to a Li-Ion cell?
The MCP73834T-FCI/UN supports a programmable charge current of up to 1 A, set by a single external resistor connected to the PROG pin. This allows designers to target any charge rate from a few tens of milliamps up to 1 A to suit battery capacities ranging from 100 mAh to 1000 mAh.
Over what input voltage range does MCP73834T-FCI/UN operate reliably?
The device operates from a 4.5 V to 6 V input supply, making it compatible with USB 5 V bus power and typical 5 V wall adapters. Built-in input overvoltage protection guards the charger and battery against transients above 6 V during normal charging cycles.
How does the adjustable termination threshold help extend battery lifespan in wearable devices?
By lowering the termination threshold below the default 4.2 V full-charge voltage, designers can reduce per-cycle top-off stress on the cell, potentially doubling cycle life from roughly 500 cycles to over 1000 cycles in wearables that charge daily.
Is MCP73834T-FCI/UN suitable for use in automotive or industrial environments?
The MCP73834T-FCI/UN is specified over a -40°C to +85°C ambient temperature range and is RoHS-compliant with Pb-free MSOP-10 packaging, making it suitable for industrial handheld instruments and in-cabin automotive accessories where a regulated 5 V USB source is available.
