Description
The DA6102 is a highly integrated multi-channel PMIC designed for 2-cell Lithium-ion battery-powered systems. The wide input voltage range allows direct battery connection for each channel to maximize battery life. The PMIC also includes a highly accurate input current sense with circuit breaker control for battery current sensing and overcurrent shutdown.
The DA6102 integrates two buck regulators, a buck-boost regulator, a high current buck controller, and two always-on LDOs. This high level of integration combined with high-frequency operation (up to 3MHz) minimizes both PCB size and external component count for the smallest possible solution size. The DA6102 uses extremely low RDSON FETs to enable very high-efficiency buck and buck-boost regulation.
Benefits
- High efficiency
- Wide input voltage range
- Highly programmable start-up sequencing and protection features on each channel
- High accuracy ±1% input current sense monitoring
- High frequency operation – Low-profile components
