Charging regulator IC for secondary batteries is compatible with CV charging
Torex Semiconductor has launched the XC6242 series, a charging regulator IC specialising in CV (constant voltage) charging that is compatible with secondary batteries with an operating temperature range of 105 degrees C.
In recent years, a variety of battery types, such as semi-solid state batteries and all-solid state batteries, have been developed. The XC6242 series is a dedicated IC optimised for CV charging of 2.3V small lithium secondary batteries (LTO batteries). By supporting the operating temperature of +105 degrees C, it has become possible to charge CV to batteries used in high temperature environments such as industrial applications.
The charging regulator ICs have an output voltage compatible with the charging voltage of 2.3V-type lithium secondary batteries, and are capable of charging without exceeding the maximum charging voltage limit of secondary batteries in temperatures of up to +105 degrees C. While charging is not being performed, the sink current to charging ICs from secondary batteries can be kept to a low level, contributing to the extension of battery drive times.
The package uses ultra-compact and low-profile USPN-4 (0.9 x 1.2 x 0.4mm) which contributes to the miniaturisation of the entire device.
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 making up its core product offering.
