Low-Cost: Flexible Voltage Supervisor and Battery Tester Reference Design
Description
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.
Features
- 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 supervisionLow Cost to design for customized voltage supervisionFootprint can fit on the backside of a single AA battery voltage holderNo Firmware or Software Needed
