Note 1: Power dissipation is 200 mW when in Free Air. Derate at 1.6 mW/°C for operation above 25 °C.
Note 2: The resistance values of R1 and R2 can be calculated as follows: R1 = Vref x TSH / (TSET x ISH - (TSET -TSH) x IIB), R2 = TSET x TC x R1 / (Vref -
R1 x IIB - TSET x TC). IIB is 0.1 µA and ISH is 1.25 µA.
Note 3: When VPTAT < COMP IN, COMP OUT > 2.8 V (High Level). When VPTAT > COMP IN, COMP OUT < 0.3 V (Low Level).
Note 4: VPTAT does not have an output pin.
