Functions
* Current linear drive * Control V type amplifier * Separate power supply for output upper side bias circuit allows low output saturation by boosting this power supply only (useful for 5V power supply types). * Upper side current detection technique reduces loss voltage of current detection resistor. Voltage drop caused by this resistor reduces internal power dissipation of IC. * Built-in short braking circuit * Built-in reverse blocking circuit * Hall FG output * Built-in S/S function * Built-in current limiter circuit (selectable, 2 steps) * Built-in Hall power supply * Built-in thermal shutdown circuit * Supports 3.3V DSP
