The LTC3337 integrates additional SoH variable monitoring which measures and reports via I2C: battery voltage, battery impedance, and temperature. To accommodate a wide range of primary battery inputs, the peak input current limit is pin selectable from 5mA to 100mA. This enables the IC to present the battery with a load profile which allows it to deliver its maximum capacity, independent of the actual load. This is “battery friendly” and prolongs the lifetime of the cell. The LTC3337 is ideal for primary cell applications that require only occasional power such as applications in remote locations, electronic door locks, or glass break detectors. The device may also be used in rechargeable battery cell applications.
LTC3337 Key Features:
- Battery Input Voltage Range: 1.8V to 5.5V
- 100nA Quiescent Current
- 8 Primary Battery Peak Input Current Limits:
- 5mA/10mA/15mA/20mA/25mA/50mA/75mA/100mA
- SoH Monitor for Primary Battery
- Integrated Coulomb Counter (Q) Additional Monitors for Battery Voltage (V), Battery Impedance (Z), and Temperature (T)
