What are the key features of LTC2945IMS#TRPBF?
- Wide voltage monitoring range with I2C/SDAO interface enables real-time reporting of voltage, current, and calculated power to host processor over a 2-wire bus
- Adjustable alert thresholds for over-voltage, under-voltage, over-current, and over-power conditions allow autonomous fault detection without continuous CPU polling
- 12-pin MSOP (JESD-30 R-PDSO-G12) package with tape-and-reel packaging minimizes PCB area and supports high-volume automated SMT assembly
What is LTC2945IMS#TRPBF used for?
The LTC2945IMS#TRPBF is used in telecom line cards, server power supply units, and industrial equipment for continuous monitoring of supply rails from sub-volt to high-voltage bus levels. Its I2C interface and autonomous alerting make it ideal for battery management systems, datacenter power distribution units, and multi-rail embedded systems requiring remote power telemetry without dedicated ADC channels.

Frequently Asked Questions
What electrical quantities can the LTC2945IMS#TRPBF measure and report over I2C?
The LTC2945IMS#TRPBF measures voltage across the sense resistor, bus voltage, and calculates power as the product of these two, reporting all three values as digital codes over the I2C/SDAO bus. Internal 12-bit ADCs convert these analog quantities, giving the host processor accurate real-time telemetry without external ADC hardware, and adjustable alert thresholds trigger an interrupt when any parameter exceeds programmed limits.
How do adjustable thresholds on LTC2945IMS#TRPBF reduce host CPU intervention in power monitoring?
The LTC2945IMS#TRPBF stores programmable high and low threshold registers for voltage, current, and power. When any monitored value crosses a threshold, the ALERT pin asserts an interrupt to the host processor, eliminating the need for continuous polling at 1 ms intervals or shorter. This allows the CPU to remain in a low-power sleep state for extended periods, waking only on genuine fault conditions on 3.3 V, 5 V, or 12 V supply rails.
What package does LTC2945IMS#TRPBF use and how does it compare in size to a standard SOIC-16?
The LTC2945IMS#TRPBF uses a 12-pin MSOP (Mini Small Outline Package, JESD-30 R-PDSO-G12) with a 0.65 mm pin pitch and a body approximately 4.9 mm × 3 mm. This is roughly 60% smaller in board area compared to a standard SOIC-16 package, making it preferable in densely populated power monitoring circuits on server blade or instrument PCBs.
In which server or telecom applications is LTC2945IMS#TRPBF commonly deployed?
The LTC2945IMS#TRPBF is frequently deployed on telecom line cards monitoring -48 V or 3.3 V rails, server power supply boards tracking 12 V bus current draw per slot, and blade server chassis measuring per-blade power consumption for data center power budgeting. Its wide input range supports monitoring supplies from sub-1 V low-voltage DDR rails to high-voltage 48 V distribution buses in a single part number.
