The STTS751-0DP3F from STMicroelectronics is a low-voltage local digital temperature sensor designed for accurate thermal monitoring in compact, power-sensitive electronic systems.
Built with an SMBus 2.0-compatible interface, programmable resolution, low supply current, and alert functionality, this device is ideal for applications that need reliable temperature measurement without adding unnecessary power demand.
The STTS751-0DP3F measures local temperature and communicates data over a 2-wire SMBus-compatible interface. It offers programmable resolution from 9-bit to 12-bit, allowing engineers to balance measurement sensitivity, conversion speed, and power consumption based on application needs.
Here’s what you’re getting with this part:
Key Features of the STTS751-0DP3F:
Low-Voltage Operation
The device operates from 2.25V to 3.6V, making it suitable for low-voltage designs used in portable electronics, notebook computers, smart batteries, and other compact electronic systems.
Programmable Temperature Resolution
The sensor supports four resolution settings, from 9-bit to 12-bit. This gives engineers the flexibility to choose between faster conversion times or finer temperature measurement.
Low Supply Current
The STTS751-0DP3F is designed for efficient thermal monitoring, with low typical current consumption during operation and an even lower standby current for power-sensitive systems.
SMBus 2.0-Compatible Interface
With a 2-wire SMBus-compatible interface and support for serial clock rates up to 400kHz, the device can be integrated into digital monitoring and control systems.
One-Shot Mode for Power Saving
The one-shot function allows the sensor to perform a single temperature conversion on demand while in standby mode before returning to low-power operation, helping reduce average power consumption.
Alert Output for Temperature Limits
The open-drain EVENT output can indicate when the measured temperature exceeds a programmed high limit or falls below a programmed low limit, supporting system response to thermal changes.
Addr/Therm Pin for Address Selection and Thermal Control
The Addr/Therm pin allows SMBus address selection using a pull-up resistor and can also support overtemperature response, such as controlling a fan or triggering system-level protection.
Selectable SMBus Addresses
The STTS751-0DP3F supports four selectable SMBus addresses through the Addr/Therm pin. This allows multiple sensors to share the same 2-wire SMBus and monitor different temperature zones within an application. Across the wider STTS751 family, up to eight devices can share the same bus.
Applications of the STTS751-0DP3F:
The STTS751-0DP3F is suitable for a range of thermal monitoring applications, including:
- Solid state drives
