What are the key features of LM75BIM-5?
- 9-bit digital temperature output with ±2°C accuracy over -55°C to +125°C range
- I2C interface supports up to 8 devices per bus via 3 address pins
- Programmable overtemperature OS/ALERT output for autonomous thermal shutdown or interrupt
- Low 3.3 V to 5.5 V supply voltage with standby mode for energy-efficient designs
What is LM75BIM-5 used for?
The LM75BIM-5 is used in system thermal management applications such as server motherboards and network switches where per-zone temperature monitoring triggers fan speed adjustment or thermal shutdown. It is also common in industrial control panels, battery chargers, and HVAC systems needing I2C-connected temperature sensing with alert thresholds. The 8-address-select feature allows multiple sensors to be distributed across a PCB and polled by a single microcontroller over one I2C bus.

Frequently Asked Questions
What temperature measurement resolution and accuracy does LM75BIM-5 provide?
The LM75BIM-5 provides 9-bit temperature resolution, corresponding to 0.5°C per LSB, with a maximum accuracy of ±2°C over its full -55°C to +125°C operating range. This resolution is sufficient for thermal management decisions such as fan speed control and overtemperature shutdown in server and networking equipment.
How many LM75BIM-5 sensors can be connected on a single I2C bus?
Up to 8 LM75BIM-5 sensors can be connected on a single I2C bus by setting different logic levels on the three address pins (A0, A1, A2). This allows a single microcontroller to monitor 8 thermal zones simultaneously without additional bus multiplexers, ideal for multi-zone thermal management in server boards or industrial enclosures.
How does the overtemperature alert output of LM75BIM-5 function in a thermal protection circuit?
The LM75BIM-5 OS pin asserts low when the measured temperature exceeds the programmable TOS threshold register value, and deasserts after the temperature falls below the THYST hysteresis threshold. In a protection circuit, this open-drain output can be connected to a microcontroller interrupt pin with a 10 kΩ pull-up, or directly to a fan-speed controller or power-switch enable pin to trigger cooling or shutdown without software polling.
Is LM75BIM-5 compatible with 3.3 V microcontrollers, and what is its current consumption?
The LM75BIM-5 operates from 3.3 V to 5.5 V, making it directly compatible with 3.3 V microcontrollers without level shifting. In active measurement mode it consumes approximately 250 µA, and in shutdown mode it drops to under 3 µA. This low standby current makes it suitable for battery-powered temperature logging applications with infrequent wake-up cycles.
