Uln2003 Schaltung. Maximum power dissipation is a function of tj max rthja and ta. Npn transistor array mit gem.
Relay driver ic uln2003 is high voltage and high current integrated ic which used darlington array. 3 3v eingang 5v ausgang. The uln2003 is known for its high current high voltage capacity.
The maximum allowable power dissipation at any allowable ambient temperature is pd tj max ta rthja.
4 phase uln2003 stepper motor driver pcb the uln2003 stepper motor driver pcb provides a direct drive interface between your microcontroller and stepper motor. Stmicroelectronics alldatasheet datasheet datasheet search site for electronic. It has the capacity to drive 500ma into a single channel upto 250ma per channel if four of the seven channels are active and 125 ma per channel if all the seven channels are active. 500 ma rated collector current single output 50 v output there is a version that supports 100 v output.
