STMicroelectronics N.V. (ST) releases the STC3105, a stand-alone battery-monitoring IC in a compact 2 x 3 x 0.8mm package targeted at increased battery runtime and lifespan in handheld applications such as mobile phones, multimedia players, digital cameras and other space-constrained portable devices.

ST's battery-monitor IC measures battery voltage and current using open-circuit voltage and coulomb-counter methods to estimate the battery capacity and to manage and track charge/discharge status. Accurate predictions of the battery state of charge and time-to-empty help avoid unnecessary recharging, extend operating time between charges and lengthen the battery lifespan, according to ST.


The STC3105 boasts low supply-current requirements—60µA typical.

The STC3105 flaunts low supply-current requirements—60µA typical. The power-saving mode reduces current consumption in the IC, as well as enabling low standby-power levels in the final application.

Integrating a programmable alarm output, the STC3105 can alert the system when the battery state of charge is below a certain level. Such embedded intelligence helps initiate appropriate power management actions when the battery is nearly empty without involving the system microcontroller, enabling the microcontroller to spend longer times in a sleep mode, decreasing the overall power consumption.

The STC3105 stand-alone battery-monitoring IC, with alarm output, is available in volumes, with unit pricing at Rs.51.02 ($1) in quantities of 1,000 pieces.
