Product Overview
DS2488X+U is a 1-wire dual-port link. It is a simple bridge device that with a single dedicated contact on each side of the bridge enables upto 512kbps pass-through communication, power delivery for battery charging, small message exchange, and state reporting between two microcontroller-based subsystems. An example application is true wireless stereo (TWS) earbuds containing a Bluetooth® Audio SoC and the microcontroller-operated case that holds and charges the earbuds. In this scenario, the DS2488 would reside in earbuds alongside the SoC, and the charging case microcontroller would communicate with the DS2488 from a single dedicated pin. All of this is enabled with the flexibility of a 1-wire interface, which is used to operate each of the two independent I/O ports, IOA and IOB. It is used in applications such as true wireless stereo earbuds and charger boxes, communication and control bridging, wearable devices, and electronic locks.
- Small message exchange between a case and earbuds, earbud battery charger power delivery
- Three GPIO pins for optional feature control or state detection
- Earbud 64-bit identification number (ROM ID) readable upon insertion
- Operating power parasitically derived from the 1-wire IOA line
- Detect when in or out of a charging case, detect a dead charging case battery
- Single dedicated contact for communication and power
- Propagation delay is 600ns maximum at (TA = +25°C)
- 512kbps maximum data rate at (TA = +25°C)
- Supply capacitance is 2nF typical at (TA = +25°C)
- Operating temperature range from -40°C to +85°C, 8-pin WLP package
