AM4963R

Data Sheet Single Phase Full Wave Direct PWM Motor Driver AM4963/AM4963R 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 HTSSOP-14 SSOP-16 Figure 1.
