MP86920GLV-Z

MP86920GLV-Z is a high-efficiency dual-channel motor driver IC from Monolithic Power Systems designed to drive small BLDC or stepper motors in compact electronics. It integrates high/low-side MOSFETs and control logic, enabling direct interfacing with a microcontroller or PWM controller. Key features include adjustable current limit via an external sense resistor, programmable operating modes for 2‑phase stepper or BLDC commutation, and built‑in protections (overcurrent, over/undervoltage, thermal shutdown). The device supports versatile control schemes (PWM, speed/torque control) and options for braking or idle-current reduction to improve efficiency. The GLV-Z variant comes in a compact, RoHS-compliant package suitable for space-constrained boards. Common applications include printers, 3D printers, robotics actuators, cooling fans, and other small motor drives. For exact electrical specs, pinout, and application guidance, consult the MP86920GLV-Z datasheet from Monolithic Power Systems.

Here are typical features of MP86920GLV-Z (Monolithic Power Systems BLDC motor driver IC in GLV package):
