ST’s portfolio of battery management ICs includes:

  • Battery monitoring fuel gauge ICs combining a small footprint with outstanding measurement accuracy (voltage, current and temperature) and extremely low power consumption to increase battery runtime and lifespan in mobile phones, multimedia players, digital cameras, and other space-constrained portable devices.
  • Battery chargers that offer charge currents from as little as 200 mA up to 1.2 A and that can be used for any rechargeable chemistry lithium-ion battery.

STC3117 provides high accurate battery monitoring

The STC3117 is a gas gauge IC with battery charger control for handheld applications. It includes the ST’s Patented OptimGauge™ algorithm for accurate battery capacity calculation. 

Li-Ion linear charger with load switches and smart reset generator

The STBC02 and STBC03 battery-charger management chips improve integration without compromising performance and power consumption. They combine a linear battery charger, a 150 mA LDO, two SPDT switches and a Protection Circuit Module for the battery. Moreover, the STBC02 features a digital single wire interface and a smart reset/watchdog function.

In addition to a shipping mode that maximizes battery life during the end product’s shelf life, both devices feature a charger enable input to stop the charging process anytime and are automatically powered by the connected battery when the IN pin is not connected to a valid power source (battery mode).

The STBC02/03 offers the perfect solution for wearable and IoT markets, reducing the application cost, footprint and design time.
