Description
   The A4939 is a three-phase controller for use with N-channel external power MOSFETs and is specifically designed for automotive applications.
   A unique charge pump regulator provides full (>10 V) gate drive at battery voltages down to 7 V and allows the A4939 to operate with reduced gate drive at battery voltages down to 5.5 V. A bootstrap capacitor is used to provide the above battery supply voltage required for N-channel MOSFETs.

FEATUREs and Benefits
• High current 3-phase gate drive for N-channel MOSFETs
• Cross-conduction protection
• 5.5 to 50 V supply voltage range
• Regulated logic supply voltage output option
• Motor phase short to supply and short to ground detection
• Undervoltage, overtemperature monitors
• Low current Sleep mode option

APPLICATIONs
• Electronic power steering (EPS, EHPS, EAS)
• Hydraulic pumps
• Engine cooling fan
• Gearbox actuator
