Electronic devices used in automotive applications often require efficient, powerful, and cost-effective power management solutions. One of these solutions is the L9958XPTR, a highly integrated and versatile power management integrated circuit (PMIC). It was designed to drive 3-phase brushless DC (BLDC) motors, stepper motors, and permanent magnet synchronous motors (PMSM). It is well-suited for various industrial and automotive applications, including air conditioner compressors and other industrial and automotive applications.

The L9958XPTR is a fully integrated PMIC which includes a gate driver, a controller, and a gate driver circuit which can drive up to three-phase BLDC or stepper motors. The integrated gate driver circuit provides a level of protection against motor over-current or under-voltage conditions. The integrated controller then provides the signal feedback to the gate driver in order to ensure optimal motor performance.

The integrated gate driver circuit provides the capability to control the motor in either open loop or closed loop mode. The open loop mode utilizes the driver’s on-board pre-determined commands to drive the motor while the closed loop mode uses feedback signals from the motor to adjust the motor speed or position. This provides smooth motor operation in either a running or a stationary condition.

The L9958XPTR includes additional circuitry to support protections, such as over-current protection and thermal protection, as well as advanced diagnostics capabilities. These additional features help to ensure a better and safer driving experience for the user.

The L9958XPTR is a highly integrated, versatile and cost-effective PMIC suitable for various industrial and automotive applications. It is easy to use and can be applied in various types of motors. This PMIC can control three-phase brushless DC (BLDC) motors, stepper motors, and permanent magnet synchronous motors (PMSM). It offers excellent protection, robust diagnostics and fault feedback, as well as low system cost.
