Analog Devices Inc. LT8491 Buck-Boost Battery Charge Controller
Analog Devices Inc. LT8491 Buck-Boost Battery Charge Controller implements a constant-current constant voltage (CCCV) charging profile used for most battery types. This includes sealed lead-acid (SLA), flooded, gel, and lithium-ion. The device operates from input voltages above, below, or equal to the output voltage and is powered by a solar panel or DC power supply.
Features
- 6V to 80V input voltage range
- 1.3V to 80V voltage battery range
- Single inductor allows VIN above, below, or equal to VBAT
- Automatic MPPT for solar-powered charging
- Automatic temperature compensation
- I2C telemetry and configuration
- Internal EEPROM for configuration storage
- Operation from a solar panel or DC supply
- Four integrated feedback loops
- 100kHz to 400kHz synchronizable fixed frequency range
- 64-lead (7mm x 11mm x 0.75mm) QFN package
Applications
- Solar-powered battery chargers
- Multiple types of lead-acid battery charging
- Li-Ion battery chargers
- Battery-equipped industrial or portable military equipment
