Motor Driver and Motion Controller ICs

Small, silent, precise, and extremely efficient with a standby current draw of <50nA (typ.), ADI Trinamic's battery-powered motor drivers set the standard for IoT, home automation, and handheld devices. Together with the lowest-in-class RDSon of LS 170mO and HS 170mO (typ.), these motor driver ICs save battery life like no other.

ADI Trinamic’s integrated 3-phase driver ICs for brushless DC (BLDC) motors and PMSM allow you to design highly efficient drives. The drivers allow for control for sine-commutation of 3-phase motors using 6-line control or SPI from the CPU. Power MOSFETs, a charge-pump, and current feedback options are all packed on the 3-phase driver for BLDC and PMSM motors, making it a highly efficient solution for powerful drives.

ADI Trinamic's DC motor driver ICs integrate a highly efficient power stage with internal charge pump, delivering best-in-class RDSon resistance. Even at low supply voltages, the tiny DC motor driver chips provide high current for best results. With full control via UART, protection and diagnostics allow for robust and reliable operation of DC drives, supporting cost-effective system designs with efficient and reliable operation.

Dedicated motion and interface controllers for stepper motors offload the MCU from real-time critical tasks, calculating ramping and positioning in proven, integrated hardware that's safe and secure. The single bi-directional interface SPI for motion commands and diagnostics keeps the count of required lead traces low, enabling extremely miniaturized and lean designs. Some motion and interface controllers also support S/D to simplify control of stepper motors.

Monolithic solenoid driver ICs are designed to make the control of valves and solenoid actuators more accurate and energy efficient. Although driving solenoids can be as simple as switching the current flow on and off, ADI Trinamic solenoid driver ICs offer proprietary diagnostic functions and automatic current reduction.

ADI Trinamic's stepper motor drivers minimize overall power consumption and system cost by integrating everything into one single package – including predrivers, sensing, protection circuitry, and power bridges. Allowing for powerful, flexible designs with a high current profile that perfectly matches the motor, these stepper motor driver ICs greatly reduce design complexity and development time.
