MCP73831-2ATI/OT规格书详情
Description
The MCP73831/2 devices are highly advanced linear
charge management controllers for use in spacelimited,
cost-sensitive applications. The MCP73831/2
are available in an 8-Lead, 2 mm x 3 mm DFN package
or a 5-Lead, SOT-23 package. Along with their small
physical size, the low number of external components
required make the MCP73831/2 ideally suited for
portable applications. For applications charging from a
USB port, the MCP73831/2 adhere to all the
specifications governing the USB power bus.
The MCP73831/2 employ a constant-current/constantvoltage
charge algorithm with selectable
preconditioning and charge termination. The constant
voltage regulation is fixed with four available options:
4.20V, 4.35V, 4.40V or 4.50V, to accommodate new,
emerging battery charging requirements. The constant
current value is set with one external resistor. The
MCP73831/2 devices limit the charge current based on
die temperature during high power or high ambient
conditions. This thermal regulation optimizes the
charge cycle time while maintaining device reliability.
Several options are available for the preconditioning
threshold, preconditioning current value, charge
termination value and automatic recharge threshold.
The preconditioning value and charge termination
value are set as a ratio or percentage of the
programmed constant current value. Preconditioning
can be disabled. Refer to Section 1.0 “Electrical
Characteristics” for available options and the
Product Identification System for standard options.
The MCP73831/2 devices are fully specified over the
ambient temperature range of -40°C to +85°C.
