DESCRIPTION

The DS56 Dual Temperature Comparator has two independent open-drain thermostat outputs and

respective trip point inputs. The trip points 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 temperature 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 thermostat 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/temperature-sensitive environments.
