BD62220AEFV
General Description
BD62220AEFV is a built-in 2 channel H-bridge motor
driver for 2 DC brush motors or 1 stepper motor. This
driver can facilitate low power consumption by direct
PWM or PWM constant current control. There are built in
protection circuits in this IC. It is possible to output an
abnormal detection signal for Wired-OR that notifies each
protection circuit operation, which contributes to set high
reliability.
Features
Single Power Supply Input (rated voltage of 36V)
Rated Output Current (peak): 2.0A(2.8A)
Low ON-Resistance DMOS Output
Forward, Reverse, Brake, Open
Power Save Function
External PWM Control
PWM Constant Current Control (current limit function)
Built-in Spike Noise Cancel Function (external noise
filter is unnecessary)
Driver for 2 DC Brush Motor
Driver for 1 Stepper motor
FULL STEP, HALF STEP (driving stepper motor)
µSTEP Drive by External DAC (driving stepper motor)
Built-in logic input pull-down resistor
Cross-conduction Prevention Circuit

Ghost Supply Prevention (protects against malfunction
when power supply is disconnected)
Adjacent Pins Short Protection
Inverted Mounting Protection
Microminiature, ultra-thin and high heat-radiation
(exposed metal type) HTSSOP-B28 package
Application
Plain Paper Copier (PPC), Multi-function Printer, Laser
Printer, Inkjet Printer, Photo Printer, FAX, Mini Printer and
etc.
