Tiny I2C-Controlled Single-Cell Charger Reference Design for Wearable Applications
Texas Instruments
This is a single-cell charger reference design for wearable applications which have very limited design space. TIDA-03042 works with a host controller through I2C control: supports 5-V: 9-V: or 12-V input adaptors and can charge up to 1.5 A. The actual charger design only requires a space of 1.7 cm²: allowing for high-charging efficiency while minimizing the total count of components and board size.
Features
- Up to 1.5 A single-cell chargerCharge efficiency of 92% at 0.5 A and 1.5 ALow-power PFM mode for light-load operationsHigh-input voltage operation range from 3.9 V to 14 V
