AM4963 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.
