... SERIAL-INPUT, LATCHED SINK DRIVER The UCN5829EB is designed to drive high-current 24-wire (3 devices cascaded) dot matrix impact printer solenoids. The internal CMOS control logic: 1) selects the operating channels from 24-bit word previously loaded into the shift register, 2) controls the peak load current of the output drivers via nine ...

... The chopping function is disabled when V operation at higher than allowable current levels, V exceed 3.2 V, except to disable the chopping function. For correct operation of the UCN5829EB, the duty cycle must be between 15% and 50% with 20% to 40% recommended. The lower limit is due to internal lockout circuitry while the upper limit guarantees synchronous operation ...
