NSD7315 series is a H-bridge Brushed DC motor driver IC which capable to withstand 40V abs. and 10A peak output. Its output slewrate is configurable and integrates current sensing function, open-load detection diagnosis and full protection features(UVLO, CPUV, OCP, TS, nFAULT output). The IC has both hardware and SPI interface version, and can be configured as 1 H-bridge or dual half-bridge, to drive 1 BDC motor or 2 valves .etc. loads.
