Зарядный насос (1), линейный (LDO) (1)2±5 В, 5,7 В ~ 10,8 В, 50 мА2,85 В ~ 6,5 В

Overview

The LM2686MTCX/NOPB is a precision, single digital-output, low-power thermostat comprised of an internal reference, DAC, temperature sensor and comparator. Utilizing factory programming, it can be manufactured with different trip points as well as different digital output functionality. The trip point (TOS) can be preset at the factory to any temperature in the range of 55°C to 110°C in 1°C increments. The LM2686MTCX/NOPB has one digital output (OS/OS/US/US), one digital input (HYST) and one analog output (VTEMP). The digital output stage can be preset as either open-drain or push-pull. In addition, it can be factory programmed to be active HIGH or LOW. The digital output can be factory programmed to indicate an over temperature shutdown event (OS or OS) or an under temperature shutdown event (US or US). When preset as an overtemperature shutdown (OS) it will go LOW to indicate that the die temperature is over the internally preset TOS and go HIGH when the temperature goes below (TOS–THYST). Similarly, when preprogrammed as an undertemperature shutdown (US) it will go HIGH to indicate that the temperature is below TUS and go LOW when the temperature is above (TUS+THYST). The typical hysteresis, THYST, can be set to 2°C or 10°C and is controlled by the state of the HYST pin. A VTEMP analog output provides a voltage that is proportional to temperature and has a 10.82 mV/°C output slope.

Available parts are detailed in the Device Comparison Table. For other part options, contact a Texas Instruments Distributor or Sales Representative for information on minimum order qualification. The LM2686MTCX/NOPB is currently available in a 5-lead SOT-23 package.
