Overview

The TMP303 devices are temperature switches used in battery-powered applications that require accurate monitoring of a very specific temperature range from 0°C to 60°C (TMP303A), 0°C to 55°C (TMP303B), –20°C to 60°C (TMP303C), –15°C to 125°C (TMP303D), 0°C to 70°C (TMP303E), 0°C to 80°C (TMP303F) or 0°C to 90°C (TMP303G). This functionality is accomplished through the preset trip window and two hysteresis bits, HYSTSET0 and HYSTSET1. The preset trip window temperature thresholds are configured at the factory; for other trip points, contact a TI representative. Table 1 summarizes the bit setting versus hysteresis temperature window.
