Description

The HA13605A is a three-phase brushless motor driver IC that provides digital speed control on chip. It

was developed for use as the drum motor driver in plain paper copiers and has the following functions and

features.

Functions

• Three-phase output circuit that can provide a maximum of 4.5 A at 35 V per phase

• Digital speed control

• Crystal oscillator circuit (10 MHz maximum)

• FG amplifier

• Speed monitor (lock detection output)

• Current control circuit

• Overvoltage protection circuit (OVSD)

• Thermal protection circuit (OTSD)

• Low voltage protection circuit (LVI)

• Forward/reverse switching circuit

Features

• High breakdown voltage, large currents

• Direct PWM drive outputs

• Employs DMOS

• Low on resistance: 0.7 Ω/DMOS maximum

• No lower arm flywheel diode is required
