Product Descriptions
The device is a single coil DC brushless motor driver IC with PWM control, lock protection, power polarity reverse protection and frequency generator. The driver is optimal for single coil fan applications with less external components.
Product Features
z Support single-phase full wave Brushless DC Motor Driver
z Built-in Hall sensor input amplifier
z Low voltage startup (VDD=1.5V)
z High output sinking and driving capability
z Lock detection and automatic self-restart
z Without external timing capacitor, Reduces the numbers of external component required
z External PWM control signal input
z With FG/2 output, suitable for 8-poles fan motor for ST1117A With FG output, suitable for 4-poles fan motor for ST1117B With RD output for ST1117C
z Thin, compact, highly reliable package (SOT-28)
