The LTC2971, LTC2971-1, LTC2971-2, and LTC2971-3 are 2-channel high voltage Power System Managers used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry and log faults.
Key Features and Benefits
● Natively sense and monitor negative voltage supplies, eliminating external level shift circuitry which saves cost, simplifies design, and improves accuracy.
● Internal EEPROM with ECC provides essential black box fault logging, allowing for faster failure analysis and system debug.
● ±0.25% TUE Differential ADC (sets trim, margin, and monitoring accuracy) improves the accuracy of 2 supplies, minimizing overdesign and cost, optimizing performance, and saving power.
Applications
● Communications/5G: -48V/+24V telecom power distribution
● High Reliability Systems
● Building and Infrastructure
● Automotive
Evaluation Board
The LTC2971 can be evaluated with the DC2875A.
