At work we are going to use this IC for a project : DRV8834.
I once again have the pleasure to think up the design. ^_^.
This IC is really a nice and easy IC, since although it packs a lot of hardware in a tiny QFN 4mmx4mmx1mm package. You can customize it fully.
Voltage is between 2.7V and 10.8V.
Current of the motors is 1.5A continuous at 5V supply.
Manufacturer is Texas Instruments.
Very nice is the internal chargepump, so 4 N-mosfets are used for each H-bridge.
The charge pump creates a voltage above the supply voltage to supply the drivers of the upper N-mosfets in the H-bridges.
I will be using this IC for my own projects as well.

By setting the level of the config pin, the ic can be used for one bipolar stepper motor or 2 dc motors. Maximum current can be set and controlled.
