The LTC2959 is an ultra-low power battery gas gauge that accurately measures charge, voltage, current and temperature. Its wide input voltage range and its low operating current make the LTC2959 suitable for many applications, including duty-cycled systems that operate over long lifetime.A precision coulomb counter integrates current through an external sense resistor connected at any point in the battery current path. A 16-bit ADC can be configured to measure voltage, current, temperature and/or an auxiliary input in single-shot, duty-cycled (1S/52s) or continuous mode (2.5kS/s). The measurements are stored in internal registers accessible via the onboard I2C/SMBus interface.The LTC2959 features programmable high and low thresholds and min/max tracking registers. If a threshold is exceeded, the device sets a flag in the internal status register and communicates an alert using the SMBus alert protocol when configured as such.APPLICATIONS Remote Sensors Energy Harvesting Systems Low-Power Handheld Products Power Tools

The LTC3108 is a highly integrated DC/DC converter ideal for harvesting and managing surplus energy from extremely low input voltage sources such as TEGs (thermoelectric generators), thermopiles and small solar cells. The step-up topology operates from input voltages as low as 20mV.
