DRV8424E 的說明

The DRV8424E/P, DRV8425E/P devices are dual H-bridge motor drivers for a wide variety of industrial applications. The devices can be used for driving two DC motors, or a bipolar stepper motor.

The output stage of the driver consists of N-channel power MOSFETs configured as two full H-bridges, charge pump regulator, current sensing and regulation, and protection circuitry. The integrated current sensing uses an internal current mirror architecture, removing the need for a large power shunt resistor, saving board area and reducing system cost. A low-power sleep mode is provided to achieve ultra- low quiescent current draw by shutting down most of the internal circuitry. Internal protection features are provided for supply undervoltage lockout (UVLO), charge pump undervoltage (CPUV), output overcurrent (OCP), and device overtemperature (OTSD).

The DRV8424E/P is capable of driving a stepper motor with up to 2.5-A full scale or brushed motors with up to 4-A peak; and the DRV8425E/P is capable of driving a stepper motor with up to 2-A full scale or brushed motors with up to 3.2-A peak (dependent on PCB design).

包裝類型選項

您可依零件數量選擇不同包裝類型選項,包含完整捲盤、客製化捲盤、剪切捲帶、承載管或盤。

客製化捲盤是從一個捲盤上剪切下來的連續剪切捲帶,以維持批次和日期代碼可追溯性,依要求剪切至確切數量。依照業界標準,銅墊片會在剪切捲帶兩側連接 18 英吋前後導帶,以直接送至自動組裝機器。針對客製化捲盤訂單,TI 將酌收捲帶封裝費用。

剪切捲帶是從捲盤剪切下來的一段捲帶。TI 可能使用多條剪切捲帶或承載盒,以滿足訂單要求數量。

TI 常以盒裝或管裝、盤裝方式運送承載管裝置,視現有庫存而定。所有捲帶、管或樣本盒之封裝,皆符合公司內部靜電放電與防潮保護包裝要求。
