Description

The LM75BDP-MS is a digital temperature sensor IC that converts thermal readings into a digital signal via a standard I2C bus. It utilizes an internal band-gap temperature sensing element, providing a stable and linear output. The sensor’s wide operating range makes it suitable for harsh environments, from industrial freezers to high-temperature enclosures.

Designed for low-power applications, it features a programmable resolution and alert function. The I2C interface allows for straightforward daisy-chaining of multiple sensors on a single bus, simplifying system design for multi-point temperature monitoring in electronic devices, HVAC controls, and battery management systems.

Frequently Asked Questions

What is the operating voltage range for the LM75BDP-MS sensor?

The LM75BDP-MS operates from a single supply voltage between 2.8V and 5.5V DC. This makes it compatible with both 3.3V and 5V logic systems commonly found in Arduino, Raspberry Pi, and other microcontroller platforms without requiring a level shifter.

How do I connect and read data from the LM75BDP-MS using I2C?

The sensor uses a standard I2C interface. Connect the SDA and SCL pins to your microcontroller's corresponding I2C pins with appropriate pull-up resistors (typically 4.7kΩ). The device has a programmable address, allowing multiple sensors on the same bus. Data is read by sending the device address and reading the two-byte temperature register.

What is the accuracy and measurement range of this temperature sensor?

The LM75BDP-MS provides a wide measurement range from -55°C to +125°C with a typical accuracy of ±3°C across the entire span. This makes it suitable for applications requiring monitoring in extreme environments, from cold storage to hot machinery enclosures.

Can this sensor be used for over-temperature alarm functions?

Yes, the LM75BDP-MS includes a programmable over-temperature alert function (OS output). You can set a temperature threshold via the I2C interface. The OS pin will assert (either high or low, programmable) when the measured temperature exceeds this setpoint, providing a hardware interrupt for system protection.
