Single-Channel Digital Output Temperature Solutions for Medical Applications

Single-channel digital output temperature sensors such as the AT30TS74  are available in ultra-small Wafer Level Chip Scale Package (WLCSP). They are a perfect fit for various products like medical applications where board space is minimal or constrained. The AT30TS74 WLCSP form factor takes up less than 1 mm² of required board space allowing it to be placed closer to the heat source being monitored, allowing for a faster thermal response to any temperature changes that occur. This is critically important for medical applications where temperature sensitivity is paramount for proper operation and enables the ability to adjust for and or take fast accurate temperature measurements. The AT30TS74 WLCSP provides a factory-calibrated accuracy of ±1.0°C with a programmable temperature window with Alert pin output to notify the host MCU of any temperature window violations. For hand-held battery-powered medical applications, the AT30TS74 features two power-saving features; a shutdown mode that turns off all of its internal circuitry saving power, and a one-shot mode that allows the AT30TS74 to make a temperature measurement, update its internal temperature registers, and then return to shutdown mode.
