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.
