DESCRIPTION
The DS56 has two independent open–drain thermostat
outputs and respective trip point inputs. The trippoints
are set with external resistors that divide down the
1.25V internal bandgap voltage reference. The voltage
resulting from this resistive division is compared with the
voltage corresponding to the device’s junction tempera-
ture to define the thermostat output logic state. The
internal temperature sensor has a typical sensitivity of
+6.2mV/
°
C and DC offset of +395 mV at 0
°
C. Both ther-
mostat outputs have 5
°
C of hysteresis.
For applications that require temperature measurement
as well as control, the temperature sensor voltage is
brought out to a pin.
The DS56 is packaged in a compact 150 mil 8–pin
SOIC. Applications include disk drives, printers, office
equipment, HVAC, appliances, or any power/cost/tem-
perature–sensitive environments.
