Product Introduction
MS8847is a dualHbridge driver circuit. Suitable for home appliances and othermechatronic applications. This device can be used to drive a stepper motor or other loads.Each output driver channel containsHbridge-configuredNchannel powerMOSFET. This design connects the ground terminal of each driver to a pin forcurrent sensing.A built-in general-purpose comparator can be used for current limiting circuits or other functionalcircuits.MS8847Each channel provides up to2.5Apeak current or1.75ARMSoutput current.The chip has overcurrent protection, short-circuit protection, undervoltage protection, and over-temperature protectionfunctions.
