SNVSBY3A November 2020 – April 2021 TLV840-Q1
PRODUCTION DATA
This design requires voltage supervision on two separate rails: 3.3-V and 1.2-V rails. The voltage rail needs to sequence upon power up with the 3.3-V rail coming up first followed by the 1.2-V rail at least 25 ms after.
PARAMETER | DESIGN REQUIREMENT | DESIGN RESULT |
---|---|---|
Two Rail Voltage Supervision | Monitor 3.3-V and 1.2-V rails | Two TLV840-Q1 devices provide voltage monitoring with 1% accuracy with device options available in 0.1 V variations |
Voltage Rail Sequencing | Power up the 3.3-V rail first followed by 1.2-V rail 25 ms after | The CT capacitor on TLV840MAPL29-Q1 is set to 0.047 µF for a reset time delay of 29 ms typical |
Maximum device current consumption | 1 µA | Each TLV840-Q1 requires 120 nA typical |
