DRV777 motor driver features 7 low output impedance drivers that minimize on-chip power dissipation. DRV777 supports 1.8V to 5V CMOS logic input interface thus making it compatible to a wide range of micro-controllers and other logic interfaces. DRV777 features an improved input interface that minimizes the input DC current drawn from the external drivers. Device also features an input RC snubber that greatly improves its performance in noisy operating conditions. All channel inputs feature an internal input pull-down resistor thus allowing input logic to be tri-stated. DRV777 also supports other logic input levels, e.g. TTL and 1.8V; see typical characteristics section for details.
As shown in the Functional Diagram, each output of the DRV777 features an internal free-wheeling diode connected in a common-cathode configuration at the COM pin.
Device provides flexibility of increasing current sink capability through combining several adjacent channels in parallel. Under typical conditions DRV777 can support up to 1.0A of load current when all 7-channels are connected in parallel. DRV777 is available in 16-pin SOIC and 16-pin TSSOP packages.
