www.DataSheet4U.com 2961 HIGH-CURRENT HALF-BRIDGE PRINTHEAD/MOTOR DRIVER 2961 The UDN2961B and UDN2961W are 3.4 A half bridges designed specifically for driving solenoid printheads, stepper motors, and dc motors. The UDN2961B/W consists of a power source driver output, a power sink driver output, a flyback recovery diode, internal current sensing circuitry, and a user-selectable fixed off-time chopper circuit. The output drivers are capable of sustaining 45 V with continuous currents of ±3.4 A and peak transient currents of ±4 A permitted. The outputs have been optimized for a low output saturation voltage (typically 2.6 V total source plus sink drops at 3.4 A).
