低成本彈性電壓監控器和電池測試器參考設計
TIDA-00670
概覽
This is a low-cost, flexible voltage supervisor that uses a voltage reference in order to test the voltage of a battery. This solution can also be used as a voltage rail monitor for many applications that require accurate power delivery with multiple rails. With TI's ultra-low power voltage references, the total system power consumption is reduced, while maintaining a low BOM cost. Testing and displaying the battery voltage provides an example of how easily this can be designed and implemented in comparable applications.
特點
- The ATL431 shunt regulator allows for voltage regulation with minimal current consumption (60 µA)
- TLV61225 boost converter enables the entire circuit to be powered from a AA battery (0.8 V to 3.3 V Input)
- User Configurable resistor ladder creates customizable number of voltage rails for supervision
- Low Cost to design for customized voltage supervision
- Footprint can fit on the backside of a single AA battery voltage holder
- No Firmware or Software Needed
