Charging ICs are compatible with lithium batteries
Charging ICs in the XC6806 series from Torex Semiconductor, have current path functions for single‐cell lithium‐ion secondary batteries.
The ICs have the current path functions which can control battery charging and supply current to systems, so that they are kept at appropriate values. Their charge completion voltages can be set to values with a wider range than previous products, for compatibility with various types of lithium batteries (where the charging voltage range is 3.5 to 4.45V). They have the shutdown functions which can completely disable the supply of power from batteries to devices. This can suppress leakage current from batteries when devices are not in use to a level as low as 100nA, making it possible for equipment such as low current consumption devices operated by small batteries to be used for even longer periods of time.
The XC6806 ICs are housed in the compact USP‐10B (2.9 x 2.6 x 0.6mm) or LGA‐10B01 (2.5 x 1.6 x 0.4mm) packages with excellent heat dissipation properties, which can be selected to suit the application.
Torex Semiconductor provides CMOS power management ICs targeted at battery powered and energy efficient applications. Torex specialises in CMOS analogue technology, with LDO voltage regulators, voltage detectors and DC/DC converters as its core product offering.
