Texas Instruments BQ25898 | Demoboard TIDA-03042
Tiny I2C-Controlled Single-Cell Charger Reference Design for Wearable Applications
Overview
| Topology | Other Topology |
| IC revision | E1 |
Description
The TIDA-03042 TI Design is a single-cell charger reference design for wearable applications which have a 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 1.5A single-cell charger
- Charge efficiency of 92% at 0.5A and 1.5A
- Low-power PFM mode for light load operations
- High-input voltage operation range from 3.9V to 14V
Typical applications
- Augmented reality glasses, Headsets/headphones & earbuds, Smart trackers, Smartwatch, Virtual reality headset, weigh scale
- Automotive test, Dashboard camera, GPS personal navigation device
- Spectrometer
