3 / 14 page 3 TCM1617 TCM1617-1 2/5/99 2001 Microchip Technology Inc. DS21485A SMBus Thermal Sensor with External Diode Input NOTES: 1. Operating current is an average value (including external diode injection pulse current) integrated over multiple conversion cycles. Transient current may exceed this specification. 2. For true reccurring conversion time see Conversion Rate register description. 3. Output current should be minimized for best temperature accuracy. Power dissipation within the TCM1617 will cause self-heating and temperature drift error. 4. Refer to Application Note 64. SMBus PORT AC TIMING: VDD = 3.3V, –55 ≤ (TA = TJ) ≤ 125°C; CL = 80 pF, unless otherwise noted.
