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
