Intended primarily to drive high-current, dot matrix 9- and 24-wire printer solenoids, the UCN5829EB serial-input, latched sink driver provides a complete driver function with a minimum external parts count. Included on chip are constant-frequency PWM current control for each output driver, a user-defined output enable timeout, current sensing, and thermal shutdown.
