General Description

BMS2662R-Q1 is an AEC-Q100 compliant 2.4GHz module targeted at wireless automotive appliaction. Such as Battery Management System (BMS) and cabel replacement.

BMS2662R-Q1 supports for TI wireless BMS protocol for robust, low latency and high throughput communication.

The module also supports functional Safety Quality-Managed classification including TI quality-managed development process and forthcoming functional safety FIT rate calculation, FMEDA and functional safety documentation.

The module is AEC-Q100 qualified at the Grade 2 temperature range (–40 °C to +105 °C).
