What are the key features of LT2940IMS#PBF?
- High-side power and current monitoring up to 80 V supply rail with single-channel measurement for direct supply rail supervision
- Adjustable threshold comparator outputs enable programmable overcurrent and overvoltage alert with no external microcontroller required
- Compact 12-lead MSOP (MSOP-12) package minimizes PCB footprint while integrating voltage, current, and power measurement in one device
What is LT2940IMS#PBF used for?
The LT2940IMS#PBF is designed for high-side power monitoring in industrial power supplies, battery management systems, and server power distribution units where continuous supervision of voltage up to 80 V and load current is required. It is also used in telecom equipment and DC-DC converter output stages to trigger protection circuits via its adjustable threshold alert outputs, reducing system complexity.

Frequently Asked Questions
What supply voltage range can the LT2940IMS#PBF monitor on the high side?
The LT2940IMS#PBF can monitor high-side supply voltages up to 80 V, making it suitable for industrial 48 V bus rails, 24 V control systems, and telecom -48 V power distribution. Its wide input range lets a single device cover multiple nominal rail voltages without external attenuation circuits.
How does the adjustable threshold in the LT2940IMS#PBF protect a power system without a microcontroller?
The LT2940IMS#PBF provides on-chip adjustable threshold comparators that assert a digital fault output when current or power exceeds a user-set limit programmed via external resistors. This hardware-level protection reacts in microseconds, safeguarding the system against overcurrent events without relying on a microcontroller or firmware polling loop.
What package does the LT2940IMS#PBF use, and how does it affect PCB layout for a dense power monitor design?
The LT2940IMS#PBF comes in a 12-lead MSOP package (approximately 3 mm × 5 mm body), which is significantly smaller than a standard 8-lead SOIC. This compact footprint allows placement close to the sense resistor on a dense PCB, reducing parasitic trace inductance and improving current measurement accuracy across the operating temperature range of -40°C to 85°C.
When should an engineer choose the LT2940IMS#PBF over a simpler current-only monitor?
Choose the LT2940IMS#PBF when a design requires simultaneous measurement of voltage, current, and computed power on a rail up to 80 V, particularly in server power supplies or industrial UPS systems where true watt-level load tracking and per-channel power budgeting are needed. Current-only monitors lack the multiplied power output and the voltage measurement channel that the LT2940IMS#PBF provides in a single 12-lead MSOP package.
