产品描述
DUAL FULL-BRIDGE PWM MOTOR DRIVER
本网站上使用的所有产品名称,商标,品牌和徽标均为其各自所有者的财产。 具有这些名称,商标,品牌和徽标的产品的描述或销售仅用于标识目的,并不表示与任何权利所有者有任何隶属关系或授权。
The UDN2917EB motor driver is designed to drive both windings of a bipolar stepper motor or bidirectionally control two dc motors. Both bridges are capable of sustaining 45V and include internal pulse-width modulation (PWM) control of the output current to 1.5A.
For PWM current control, the maximum output current is determined by the user's selection of a reference voltage and sensing resistor. Two logic-level inputs select output current limits of 0, 33%, 67%, or 100% of the maximum level. A PHASE input to each bridge determines load current direction.Active-low ENABLE inputs control the four drivers in each bridge.
The bridges include both ground clamp and flyback diodes for protection against inductive transients. Internally generated delays prevent cross-over currents when switching current direction. Special power-up sequencing is not required. Thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits.
The UDN2917EB is supplied in a 44-lead power PLCC for surface-mount applications.Its batwing construction provides for maximum package power dissipation in the smallest possible construction. The UDN2917EB is available for operation from -40℃ to +85℃. To order, change the prefix from 'UDN' to 'UDQ' . This device is also available on special order for operation to +125℃.
