Thus, the die temperature Block Diagrams in Figure5-4 through Figure5-7). A is basically the same as the package temperature. To logic signal is asserted when the die temperature minimize the error in temperature readings, the load crosses the factory-programmed threshold. An external current should be limited to a few milliamps. For hysteresis input pin allows the user to select either 2°C example, the typical thermal resistance of a 5-Pin SOT- or 10°C hysteresis to give further flexibility to the design 23A package is 140°C/W.

The TC6501 has an open-drain dissipated within the temperature sensor. This output, while the TC6502 has a push-pull output stage. corresponds to a 0.042°C rise in die temperature.

Hysteresis can be externally selected at 2°C (HYST = GND) or 10°C (HYST = V ) by means of the CC CMOS compatible HYST input pin. Do not let the HYST pin float, as this could cause an increase in supply current. The hysteresis does not depend on the part’s programmed trip threshold.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
