UCN5829 9-BIT SERIAL-INPUT / LATCHED SINK DRIVER

5829 SERIAL DATA OUT SERIAL DATA IN HIGH-SIDE DRIVER REFERENCE 9-BIT SERIAL-INPUT, LATCHED SINK DRIVER 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. The 9-bit CMOS shift regist.

UCN5829 Features

* nine open-collector Darlington drivers, each rated at 50 V and 1.6 A. Current-control for each output is provided by an internal current-sensing resistor and a constant-frequency chopper circuit. An external high-side driver can be used to optimize print head performance. It is enabled by an on-chip
