Overview
The SE98ATP,547 is a board-mounted digital temperature sensor manufactured by NXP USA Inc. It features an I2C/SMBus interface with a maximum clock frequency of 400 kHz and operates within a supply voltage range of 1.7 V to 3.6 V. The device provides an accuracy of +/- 3 °C and offers 11-bit resolution. It functions in local configuration mode with shutdown capability and operates across a temperature range of -40 °C to +125 °C. The component is housed in an 8-HWSON (2x3) package.
Feature Summary
- Digital output via standard I2C and SMBus interfaces
- Integrated internal sensing element for board-level monitoring
- Supports shutdown mode for power optimization
Applications
- General board-mounted temperature monitoring
- Embedded system thermal management
- Consumer electronics thermal protection
Procurement Notes
Verify the specific suffix '547' against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Ensure the selected variant matches the required interface speed and accuracy class for the target application environment. Cross-reference the RoHS status and lead times directly with authorized distributors prior to ordering.
Selection Notes
Select this component when a low-pin-count solution is required for basic thermal monitoring on printed circuit boards. The 8-HWSON package suits space-constrained designs. Verify that the 1.7 V minimum supply voltage aligns with the system's logic levels. Consider the +/- 3 °C accuracy tolerance against the specific thermal requirements of the application.
Part Context
This part belongs to the SE98 series of digital temperature sensors from NXP. These devices are designed for cost-effective thermal management solutions. The SE98ATP variant specifically targets general-purpose board mounting applications. It complements other NXP sensor offerings by providing a simple interface for microcontrollers without requiring complex analog signal conditioning.
Replacement Considerations
Check the SE98BTP,547 datasheet for potential functional equivalents within the same family. Confirm pinout compatibility and interface standards before substituting. Verify if the alternative part meets the specific accuracy and operating temperature requirements of the original design.
