LTC3337 | Primary Battery SOH Monitor with Precision Coulomb Counter
Analog Devices Inc.
Demonstration circuit 2973A shows the LTC3337 Primary Battery State of Health (SOH) monitor with precision coulomb counter operating with a configurable peak current limit. The LTC3337 supports input voltages from 1.8V to 5.5V and a peak current up to 100mA with a quiescent current of 100nA. Coulomb count, battery voltage, and Battery Series Resistance (BSR) are measurable and can be used to quantify the charge state and health of a battery.
The DC2973A demonstrates a simple layout for the highest-power configuration of the LTC3337. The circuit can be reduced for lower IPEAK levels. The demo board can be connected directly to a PC using a micro USB cable in order to run a GUI and configure simple a Battery State of Charge (SOC) monitor. Source code for the GUI is available and can be used as a starting point for LTC3337 firmware development.

DC414B
Analog Devices Inc.
The LTC1871 is a wide input range, current mode, boost, flyback or SEPIC controller that drives an N-channel power MOSFET and requires very few external components. Intended for low to medium power applications, it eliminates the need for a current sense resistor by utilizing the power MOSFET?s on-resistance, thereby maximizing efficiency.The IC?s operating frequency can be set with an external resistor over a 50kHz to 1MHz range, and can be synchronized to an external clock using the MODE/SYNC pin. Burst Mode operation at light loads, a low minimum operating supply voltage of 2.5V and a low shutdown quiescent current of 10?A make the LTC1871 ideally suited for battery-operated systems.For applications requiring constant frequency operation, Burst Mode operation can be defeated using the MODE/ SYNC pin. Higher output voltage boost, SEPIC and flyback applications are possible with the LTC1871 by connecting the SENSE pin to a resistor in the source of the power MOSFET.The LTC1871 is available in the 10-lead MSOP package.
