What are the key features of LTC2991IMS#PBF?
- 8-channel simultaneous voltage and differential current measurement via I2C interface with 14-bit ADC resolution
- Integrated temperature sensing supporting both internal die temperature and external diode-connected temperature measurements
- 16-pin MSOP package enabling compact system health monitoring in servers, telecom, and industrial power management applications
What is LTC2991IMS#PBF used for?
The LTC2991IMS#PBF is designed for system health monitoring in servers, telecom line cards, and industrial control systems where multiple supply rails, load currents, and board temperatures must be tracked over I2C. Its 8 measurement channels allow a single device to monitor up to 4 current-sense shunt resistors or 8 voltage nodes simultaneously. This makes it well suited for power sequencing verification, fault detection, and thermal management in high-reliability embedded systems.

Frequently Asked Questions
How many channels does the LTC2991IMS#PBF provide and what measurement types are supported on each channel?
The LTC2991IMS#PBF provides 8 input channels configurable as single-ended voltage measurements, differential voltage measurements for current sensing across a shunt resistor, or remote temperature sensing using an external diode. This flexibility allows a single 16-pin MSOP device to replace multiple discrete measurement ICs, reducing BOM count in power monitor designs for systems with 4 or more supply rails.
What I2C addressing scheme does the LTC2991IMS#PBF support and how many devices can share one bus?
The LTC2991IMS#PBF supports 8 selectable I2C addresses via two address pins, allowing up to 8 devices to coexist on a single 400 kHz fast-mode I2C bus. This enables a single microcontroller or management processor to poll up to 64 measurement channels (8 devices × 8 channels each) for comprehensive board-level power and thermal monitoring across large multi-rail power trees.
What ADC resolution does the LTC2991IMS#PBF achieve for voltage measurements and what accuracy can be expected?
The LTC2991IMS#PBF uses a 14-bit ADC for voltage measurements, providing a resolution of approximately 305 µV per LSB in single-ended mode and 19 µV per LSB in differential mode for current sensing. Typical voltage accuracy is within ±0.5% across its operating temperature range of -40°C to 85°C, making it suitable for power-supply monitoring where rail deviations of a few millivolts must be detected reliably.
For a server power monitoring board, how does the LTC2991IMS#PBF compare to using discrete voltage supervisors on each rail?
Replacing 8 discrete voltage supervisors with a single LTC2991IMS#PBF reduces the 16-pin MSOP footprint to under 30 mm², compared to 8 separate SOT-23 supervisor packages occupying 60 mm² or more. Beyond space savings, the LTC2991 delivers 14-bit measurement data over I2C rather than simple threshold alerts, enabling firmware to log exact voltage deviations, compute load power in watts, and detect gradual degradation trends before a hard fault occurs.
