High-Side Current-Sense and Internal 1°C Temperature Monitor
Datasheet
As well, the THERM pin will be asserted if the measured current or source voltage meet or exceed
the user programmed Vcrit Limit values. In this case, the THERM pin will remain asserted until all
measured voltages drop below the Vcrit Limit minus the Vcrit Hysteresis (see Section 5.23).
4.6
Temperature Measurement
The EMC1701 measures the internal or ambient temperature.
The device contains programmable High, Low, and Tcrit limits for the internal temperature channel. If
the temperature drops below the Low limit or meets or exceeds the High limit, the ALERT pin can be
asserted (based on user settings). If the measured temperature meets or exceeds the Tcrit limit, the
THERM pin is asserted unconditionally, providing two tiers of temperature detection.
