Hello~(:P)
Can I ask you some advice about DRV8801 which is full-bridge motor driver.
As the datasheet of DRV8801 shows: it provides a versatile motor driver solution with a variety of capabilities.The device contains a full H-bridge which can be used to drive a brushed DC motor,one winding of a stepper motor,or other devices such as solenoids. A simple PHASE-ENABLE interface allows easy interfacing to controller circuits. The questions I would like to ask that is :
The voltage of electronic machine is about 12.97V when non-loading. This situation is normal. However, the machine cannot operate when loading. The voltage aslo declined to about 6V. After I added a battery--12V, it’s OK to drive loading but the current here is just about 100mA. Why? You can see from the datasheet, its features are : LOW R MOSFETs (0.4ohm Typical0 and 8V--36V operating supply voltage range ?
How to solve this trouble? Please give me some feasible suggestions,thanks again !
