DRIVER CIRCUIT SPECIAL PURPOSE FOR MICROWAVE OVEN

DESCRIPTION

UTC ULN2018 include 1ch condenser buzzer driver, 4ch relay
driver, safety circuit and gate signal detection circuit. The 4ch relay
driver include: 1ch independent Darlington Transistor driver, 1ch
main relay driver, 2ch relay driver controlled by safety circuit.
Current capability of each channel driver is 100mA. Output clamp
diode is inserted in each channel to drive inductive load.

FEATURES

* Output current (single output): 100mA (MAX.)
* High sustaining voltage output: 50V (MIN.)
* Output clamp diodes
* TTL/CMOS logic level is compatible.
