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 driver during the output enable timeout. Internal logic sequencing prevents false output operation during power up. Other high-current devices for driving dot matrix printheads are the UDN2961B/W and UDN2962W. The UCN5829EB is supplied in a 44-lead power PLCC. Its batwing construction provides for maximum package power dissipation in a minimum-area, surface-mountable package.
