The Allegro MicroSystems A3946KLPTR-T is a versatile Half-Bridge Power MOSFET Controller engineered for applications requiring high power unidirectional DC motors or three-phase brushless DC motors. It features two high-current gate drive outputs capable of driving a wide range of N-channel MOSFETs, with an integrated top-off charge pump enabling DC (100% duty cycle) operation.
This controller supports a wide operating voltage range from 7V to 60V, with a maximum load supply voltage of 60V. It operates reliably within an ambient temperature range of -40°C to 135°C. The device includes essential protection features such as overtemperature and undervoltage protection.
The A3946KLPTR-T is supplied in a 16-lead TSSOP package with an exposed thermal pad, suitable for surface mounting. This package type, along with its robust feature set, makes it a suitable choice for demanding motor control applications.
