TIDA-00394
概覽
Many systems require a backup battery to provide power in the event of a power outage. Switching between the main power and the backup battery power without incurring significant efficiency degradation or cost is a tricky challenge. This design provides a high accuracy, low current solution for systems using a 12 V rail with a backup battery at a lower cost than existing devices.
特點
- Low current consumption in battery backup mode: 28 uA
- High voltage threshold accuracy: 1.75% including resistors
- Independent voltage programming on primary and secondary rails
已開發完全組裝的電路板，僅供測試與性能驗證，且為非賣品。
