Single Phase Full Wave Direct PWM Motor Driver AM4963/AM4963R

Features

General Description

•

The Motor Speed is Controlled by PWM Pulse

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.

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

•

The AM4963/AM4963R is available in HTSSOP-14

and SSOP-16 packages.
