Frequently Asked Questions
What is the maximum input voltage the LTC2945HUD#PBF can monitor?
The LTC2945HUD#PBF supports input voltage monitoring up to 100 V, making it suitable for industrial and telecom bus rails including 48 V and 72 V supply systems with a single IC.
How does the LTC2945HUD#PBF communicate with a host microcontroller?
It uses an I2C interface operating at standard 100 kHz or fast 400 kHz mode, allowing straightforward integration with any microcontroller that supports the I2C protocol for reading power data registers.
What ADC resolution does the LTC2945HUD#PBF provide for power measurements?
The device integrates a 12-bit ADC, delivering fine-grained resolution for current, voltage, and power readings, enabling detection of load changes as small as a few milliamps on the monitored rail.
Which package does the LTC2945HUD#PBF use and how does it affect PCB layout?
The part is housed in a compact QFN-12 package with an exposed thermal pad, occupying minimal PCB area while providing good thermal dissipation. The 3 mm x 3 mm footprint suits density-constrained layouts.
When would LTC2945HUD#PBF be selected over a lower-voltage power monitor like INA219?
The LTC2945HUD#PBF is preferred when the supply rail exceeds 26 V—its 100 V range covers 48 V telecom and 72 V industrial buses where lower-voltage alternatives like INA219 (max 26 V) cannot be used.
