Single Phase Full Wave Direct PWM Motor Driver AM4963/AM4963R
Data Sheet
General Description
The AM4963/AM4963R is a full wave driver IC with
direct PWM control function and thermal resistor
control function. It is used for single phase motor and
is capable of speed control by PWM pulse and
thermal resistor at the same time.
The AM4963/AM4963R is available in HTSSOP-14
and SSOP-16 packages.
Features
The Motor Speed is Controlled by PWM Pulse
•
Directly and Thermal Resistor at the Same Time
• Low Corner Temperature (30°C) Adjustable
• High Corner Temperature (38°C) Adjustable
• Full Speed when Thermal Resistor Shorten
• Built-in Triangle Wave Circuit without Extra
Oscillation Capacitor
• Built-in Minimal Speed Setup Circuit
• Alpha Slope Adjustable
• Rotation Speed Indicator (FG)
• Rotation/lock State Indicator (RD)
• Built-in Temperature Control Circuit
• Built-in Thermal Shutdown Circuit
• Lock Protection and Auto-restart
Applications
• CPU Cooler Fan in PC
• Brushless DC Motor Driver
