STCC05-B
HOME APPLIANCE CONTROL CIRCUIT
APPLICATIONS
■ Home Appliance digital control
■ AC Power drive and functional safety management
■ Air Conditioner, Refrigerator and Oven applications
■ Compressor, fan, heater and valve drive circuit
FEATURES
■ Wide range input supply voltage operation:
7 to 18V
■ 5 V +/- 5% full tolerance voltage regulator and
50mA output current
■ MCU reset circuit with activation delay time and
DIP-20
hysteresis (3.75V Hi, 3.4V Lo)
■ 30µs digitally filtered inverting Zero Voltage ^{Table 1. Order Code}
Synchronization
■ Three 50mA relay coil drivers with demagnetiz-
ing diode
Part Number
STCC05-BD4
Marking
STCC05-B
■ One 150mA relay coil driver with demagnetizing diode for a 20A relay
■ One 30mA peak enhanced buzzer driver with enable pin and soft turn off
■ 12 to 5V robust non inverting level shifter for speed sensor or door switch interface
■ Ambient temperature: - 20 to 85°C
BENEFITS
■ Higher module compactness with reduced component count
■ Drastic reduction of soldered pins on the board for lower use of lead metal
■ Faster module assembly time
■ High transient burst immunity and ESD robustness compliant with IEC61000-4 standards
■ Enhanced functional reliability
■ Enhanced circuit parametric quality
■ Easy to design for short time to market
