PRODUCTION DATA
An analog current-limit circuit on each MOSFET limits the current through the MOSFET by removing the gate drive. If this current limit persists for longer than the tOCP time, the MOSFETs in both H-bridges are disabled and the nFAULT pin is driven low. The charge pump remains active during this condition. The overcurrent protection can operate in two different modes: latched shutdown and automatic retry. The operating modes can be changed on the fly.
