DESCRIPTION
It provides a cycle-by-cycle current limit function for both driver channels, a programmable threshold and a digital output current limit flag which can be monitored by the host controller. With a fast cycle-by-cycle current limit protection, the driver can turn off the power stage in the event of an overcurrent condition. 2APPLICATIONS
