Features
- Motor driver block: Dual-channel, H-bridge driver (Ron(Nch+Nch)) < 350 mΩ (Max @ Tj = 150°C, VBAT = 8 V) Dual-Channel Mode and Combined-Channel Mode selectable, connecting two outputs externally allows this IC to function as a single-channel H-bridge circuit and the device is also used as a 4-channel Half Bridge driver.
- Detection features: Over-current detection, over-temperature detection, VBAT under-voltage detection, and VCC under-voltage detection.
- Initial diagnosis: Power s.
