Product Brief
Single Phase Full Wave Direct PWM Motor Driver AM4963/AM4963R
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 SSOP-16
and HTSSOP-14 packages.
