TI公司的DRV8412是具有先进保护系统的高性能全双桥马达驱动器,它的功率级效率达到97%,工作电压高达50V,最大为70V。
我也推荐一款驱动IC。IR的,超廉价高性价比。IR2103STRPBF SOP-8
Features Floating channel designed for bootstrap operation Fully operational to +600V Tolerant to negative transient voltage dV/dt immune Gate drive supply range from 10 to 20V Undervoltage lockout 3.3V, 5V and 15V logic compatible Cross-conduction prevention logic Matched propagation delay for both channels Internal set deadtime High side output in phase with HIN input Low side output out of phase with LIN input
