Replacing multiple batteries can be a time consuming and costly issue, and thus lowering the average current consumption is often a key design consideration. This reference design from Texas Instruments tackles these problems.
Features
- Over five years battery life on 4x AA batteries in series.
- 24 lock or unlock events per day.
- BLE radio connection period.
- Motor Driver has integrated FET’s and a current sense comparator which enables easy design and small solution size with minimal discrete components.
- Voltage-based battery gas gauge, integrated DC-DC converter.
- BLE tested using third party BLE iOS and Android applications.
- Configurable advertisement interval up to four seconds.
