A bandgap temperature sensor outputs a voltage proportional to absolute temperature. A 11-bit delta-sigma ADC digitizes this to 0.125\u00b0C resolution. The MSB (8 bits) can be read in a single byte for fast polling. Over-temperature shutdown (OS) output activates when temperature exceeds the programmed threshold, with configurable hysteresis for stable switching.<\/p>\n
