Abstract
An H-bridge device and an associated method for controlling an H-bridge, driving a load such as a DC current electric motor, configured to prevent any reversal of polarity in the load in an unloading phase of said load, without having to limit use of the pulse generator supplying said H-bridge in terms of duty cycle. The H-bridge device includes independent comparators and independent slope control at each of the switches of the H-bridge. Furthermore, according to one aspect, the device includes 'push-pull' drivers imposing the potential VBAT/at the connection points OUT, OUT, on either side of the load, in order to limit electromagnetic interference.
