BD63821EFV, BD63823EFV
No.12010EAT06
●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)www.DataSheet.co.kr
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.

Technical Note
●Thermal derating curve
HTSSOP-B28 has exposed metal on the back, and it is possible to dissipate heat from a through hole in the back. Also, the
back of board as well as the surfaces has large areas of copper foil heat dissipation patterns, greatly increasing power
dissipation. The back metal is shorted with the back side of the IC chip, being a GND potential, therefore there is a
possibility for malfunction if it is shorted with any potential other than GND, which should be avoided. Also, it is
recommended that the back metal is soldered onto the GND to short. Please note that it has been assumed that this
product will be used in the condition of this back metal performed heat dissipation treatment for increasing heat dissipation
efficiency.
