2962 DUAL SOLENOID/MOTOR DRIVER .PULSE-WIDTH MODULATED CURRENT CONTROL

AND APPLICATIONS INFORMATION The UDN2962W high-current driver is intended for use as a free-running, pulse-width modulated solenoid driver. Circuit Description. In operation, the source and sink drivers are both turned on by a low level at the input. The load current rises with time as a function of.

2962 Using PWM to minimize power dissipation and maximize load efficiency, the UDN2962W dual driver is recommended for impact printer solenoids and stepper motors. It is comprised of two source/ sink driver pairs rated for continuous operation to ±3 A. It can be connected to drive two independent loads or a single load in the fullbridge configuration. Both drivers include output clamp/flyback diodes, input gain and level shifting, a voltage regulator for singlesupply operation, and pulse-width m.
