Moter Drivers for Printers

Motor Drivers with Brush

for Printers

BD63821EFV, BD63823EFV

●

Description

BD63821EFV/BD63823EFV series are built-in 2 channel H-bridge circuits that can drive 2pcs DC brush motor or 1pcs

stepping motor.

These drivers facilitate low power consumption by the direct PWM or PWM constant current control.

●

Feature

1) Single power supply input (rated voltage of 36V)

2) Rated output current (peak): 1.0A(1.5A), 2.0A(2.8A)

3) Low ON resistance DMOS output

4) Forward, Reverse, Brake, Open

5) Power save function

6) External PWM control

7) PWM constant current control (current limit function)

8) Built-in spike noise cancel function (external noise filter is unnecessary)

9) Driver for 2 DC brush motor

10) Driver for 1 stepping motor

11) FULL STEP, HALF STEP (driving stepping motor)

12) µSTEP drive by external DAC (driving stepping motor)

13) Built-in logic input pull-down resistor

14) Cross-conduction prevention circuit

15) Signal output of detecting the motor lock state (Wired-OR)

16) Signal output of detecting the abnormal states (Wired-OR)

17) Thermal shutdown circuit (TSD)

18) Over current protection circuit (OCP)

19) Under voltage lock out circuit (UVLO)

20) Over voltage lock out circuit (OVLO)

21) Ghost Supply Prevention (protects against malfunction when power supply is disconnected)

22) Electrostatic discharge: 8kV (HBM specification)

23) Adjacent pins short protection

24) Inverted mounting protection

25) Microminiature, ultra-thin and high heat-radiation (exposed metal type) HTSSOP-B28 package

26) Pin-compatible line-up

●

Application

PPC, multi-function printer, laser beam printer, ink jet printer, monitoring camera, WEB camera, sewing machine, photo

printer, FAX, scanner, mini printer, toy, and robot etc.
