| 52421 SOLID STATE THERMOSTAT CONTROLLER Space Application Series... Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Features: * * * Operates With RTD Temperature Sensor Output Is Either "ON" Or "OFF" Standard And Custom Factory Settings Of: - Resistance Control Set Points (Temperatures), - Hysteresis, (Minimum/Maximum) And - Timing (On/Off Delays) Test (Load Power On/Off) Capability Optional Mounting Configurations Available Applications: Meets The Demanding Requirements Of Space Platform Environments, Where Precise Temperature Control Is Required. * DESCRIPTION Micropac's Space level Thermostat Controller 52421 operates with external RTD (Resistance Temperature Device) temperature sensor and provides a power switched (On / Off) output within a temperature window. The RTD sensor is conditioned then controls a high-side MOSFET power switch for an external HEATER. Models are available with dual channels providing either "OR" or "AND" configurations. Wired combinations of the "OR" configuration device, along with a single channel device, provides a tri-redundancy control system which guarantees both the power ON and power OFF states of the Heater ABSOLUTE MAXIMUM RATINGS Operating Temperature (TA) ........................................................................................................................ -55C to +125C Storage Temperature (TSTG) ....................................................................................................................... -65C to +165C Maximum Steady State VIN ..............................................................................................................................+132 Volts DC Peak Transient Input VIN(T) ...........................................................................................................+180 Volts DC for 5 Secs. Steady State Load Current...(Source or Sink)......................................................................................................1.1Amps.
