The A4935KJPTR-T is an automotive 3-phase MOSFET driver designed for use with N-channel external power MOSFETs. It operates within a supply voltage range of 5.5 to 50 V and features a unique charge pump regulator that enables full gate drive for battery voltages as low as 7 V. The device supports both block commutation and sinusoidal excitation for motor control, providing comprehensive control over all six power FETs in a 3-phase bridge configuration. Key features include adjustable dead time for cross-conduction protection, an uncommitted current sense amplifier for measuring bridge current, and extensive diagnostic outputs for monitoring undervoltage, overtemperature, and power bridge faults. The A4935KJPTR-T is packaged in a 48-pin LQFP with an exposed thermal pad, facilitating efficient thermal management. This product is suitable for automotive applications requiring reliable motor control and diagnostics.
The A4935 is designed for automotive motor drive applications, providing high-current gate drive up to 50V, integrated current sensing, and diagnostic features for reliable operation in harsh environments.
