DRV8841 的说明
The DRV8841 provides an integrated dual H-bridge motor driver solution for printers, scanners, and other automated equipment applications. The device can be used to drive one or two brushed DC motors, a bipolar stepper motor, or other loads. A simple PWM interface allows easy interfacing to controller circuits.

The output driver block consists of N-channel power MOSFETs configured as H-bridges. The DRV8841 an supply up to 2.5-A peak or 1.75-A RMS output current (with proper heat sinking at 24 V and TA = 25°C) per H-bridge.

A low-power sleep mode is provided which shuts down internal circuitry to achieve very low quiescent current draw. This sleep mode can be set using a dedicated nSLEEP pin. Internal protection features are provided for overtemperature, overcurrent, and undervoltage. Fault conditions are indicated by a nFAULT pin.

常见问题

1.平台上看到的库存、价格准确吗？
答：相对准确的，但也考虑到现货库存流动性比较大，目前还无法做到100%的精准。可以即时在线下单，如有异常，我们的客户经理也会及时联系你们。

2.可以提供原厂或代理的资质证明吗？
答：目前我们自营代理的品牌有近60个，其他渠道均为原厂及代理渠道，这些入驻平台时我们都严格审核过的，如有需要，我们可以针对具体品牌型号来沟通确认。

3.你们怎么保证是原厂或代理？
答：我们有专门的商务合作部门，对原厂和代理的资质进行严格的审核和认证，供应商上架物料前必须通过资质审核；我们比任何一位客户都注重产品的渠道和质量，对于供应商的审核是非常严格的，您可以放心选择！

4.鑫创华平台价格普遍较低，但为什么有某些料价格偏高？
答：我们平台品质保障是第一位的！平台上所有产品都是原厂或代理直供的，虽然不能保证每颗料都做到价格最低，但是在质量上，我们有绝对的保障，另外样品和批量的价格也是有差异的。如您有具体的型号目标价格，也可以发我们帮您申请下价格。
