The threshold switching circuit with TCAl05/TcA205A

Published:2012/9/11 1:45:00 Author:Ecco | Keyword: threshold switching | From:SeekIC

The maximum operating voltage in the circuit (a) changes from the US = 4.5V ( TCA105) 4.75V ( TCA205A) to 30V. The load here is relay coil. The current flowing load is about 3mA current in the turn-off state and IL = UL / RL ≤ 50mA in the turn-on state.
