► Output Current max. 400 mA per Half Bridge
► Three independend Pulse Detectors and Counters
► Servo Control Positioning of Actuators
► Excellent Positioning Performance
► SPI for communication with µC
► Short Circuit Protection
► Over Temperature Protection
► Battery Supply and 5V Monitor
► Diagnostic Data via SPI
► QFN 7 * 7 32 package

APPLICATION
► Positioning of HVAC Flaps (according to US patent 5,203,499 owned by BHTC)
