LV8121V 3-phase Brushless Motor Driver

Ordering number : ENA2135 LV8121V Bi-CMOS IC For Fan Motor 3-phase Brushless Motor Driver http://onsemi.com Overview The LV8121V is a three-phase brushless motor driver that uses a PWM drive technique. The motor speed is controlled by changing the PWM duty that based on an analog voltage input. This motor driver includes an automatic return constraint pro.

Features

• PWM control based on an analog voltage input (the CTL voltage), synchronous rectification
• One Hall-effect sensor FG output
• Automatic return constraint protection circuit (ON/OFF=1/15)
• Start/Stop switching circuit, Forward/Reverse switching circuit
• Current limiter circuit, Low-voltage shutdown protection circuit, Thermal shutdown protection circuit Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Supply voltage VCC max VG max VCC pin VG pin 36 V 42 V Output current Allowable power dissipation IO max Pd max t ≤ 500ms Mounted on .
