Introduction

AI Translation

The TMP23x-Q1 devices are a family of automotive-grade precision CMOS integrated circuit linear analog temperature sensors with output voltage proportional to temperature, serving automotive applications ranging from powertrain to infotainment. These temperature sensors offer a typical accuracy of ±0.5℃ over a 0℃ to +70℃ range. The TMP235-Q1 device features a positive output slope of 10mV/℃. Over the –10℃ to +125℃ temperature range and 3.1V to 5.5V supply voltage range, the high-gain TMP236-Q1 sensor provides a positive output slope of 19.5mV/℃. A typical quiescent current of 9μA and a typical power-on time of 800μs enable an efficient power-cycling architecture to minimize power loss in battery-powered devices. The Class AB output driver delivers a robust maximum output of 500μA, capable of driving capacitive loads up to 1000pF and connecting directly to ADC sample-and-hold inputs. With excellent accuracy and a robust linear output driver, the TMP23x-Q1 analog output temperature sensors are a cost-effective alternative to passive thermistors.
