LT LTC2970CUFD#PBF

电源控制器/监控器4.24mA4.5V ~ 15V

Overview

The LTC2970CUFD is a dual power supply monitor and margining controller with an SMBus compatible I2C bus interface. A low-drift, on-chip reference and 14-bit ΔΣ A/D converter allow precise measurements of supply voltages, load currents or internal die temperature. Fault management allows ALERT to be asserted for configurable overvoltage and undervoltage fault conditions. Two voltage buffered, 8-bit IDACs allow highly accurate programming of DC/DC converter output voltages. The IDACs can be configured to automatically servo the power supplies to the desired voltages using the ADC. The LTC2970-1 adds a tracking feature that can be used to turn multiple power supplies on or off in a controlled manner.

The bus address is set to 1 of 9 possible combinations by pin strapping the ASEL0 and ASEL1 pins. The LTC2970/ LTC2970-1 are packaged in a 24-pin, 4mm × 5mm QFN package.
