UDQ2916EB集成電路（IC）的電機(jī)驅(qū)動器控制器規(guī)格書PDF中文資料

UDQ2916EB屬于集成電路（IC）的電機(jī)驅(qū)動器控制器。由Allegro MicroSystems制造生產(chǎn)的UDQ2916EB電機(jī)驅(qū)動器，控制器產(chǎn)品屬于電機(jī)驅(qū)動器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機(jī)或相關(guān)機(jī)電執(zhí)行器的電源。所實現(xiàn)的具體功能和特性集根據(jù)預(yù)期負(fù)載和預(yù)期應(yīng)用的特性有很大差異，范圍從用于有刷電機(jī)的簡單開環(huán)速度控制到基于步進(jìn)電機(jī)的高級閉環(huán)運動控制。

The UDN2916B, UDN2916EB, and UDN2916LB motor drivers are designed to drive both windings of a bipolar stepper motor or bidirectionally control two dc motors. Both bridges are capable of sustaining 45 V and include internal pulse-width modulation (PWM) control of the output current to 750 mA. The outputs have been optimized for a low output saturation voltage drop (less than 1.8 V total source plus sink at 500 mA).

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.
