The LTC2977CUP#PBF from LT is an 8-channel PMBus Power System Manager designed for sequencing, trimming, margining, and supervising power supplies. It features an I2C/SMBus serial interface and can operate from 3.3V or 4.5V to 15V.
This device includes a 16-bit ADC for monitoring eight output voltages, one input voltage, and die temperature. It supports precise voltage adjustment and margining to within 0.25% of the target. The LTC2977CUP#PBF also provides overvoltage and undervoltage supervision for each channel, as well as temperature monitoring.
Programmable fault responses can disable power supplies upon detection, with optional retry functionality. Faults can trigger automatic logging of status and telemetry to internal EEPROM. The device supports autonomous operation without additional software, thanks to its configuration EEPROM with ECC.
Packaged in a 64-pin QFN measuring 9mm x 9mm, the LTC2977CUP#PBF is suitable for applications requiring robust power management and monitoring.
The device can be powered from 3.3V, or from 4.5V to 15V.
