Description
BD6387EFV, BD6385EFV, BD6383EFV, BD6389FM are the high-grade type that provides the highest function and highest reliance in the ROHM stepping motor driver series. This series has the perfect various protection circuits and reduces IC’s generation of heat by adopting low-ON resistance DMOS and high heat-radiation power package.

FEATURE
1) Power supply: one system drive (rated voltage of 36V)
2) Rated output current: 1.0A, 1.5A, 2.0A, 2.2A
3) Low ON resistance DMOS output
4) CLK-IN drive mode (built-in translator circuit)
5) Parallel IN drive mode
6) Stepping motor／ DC motor(× 2) drives are selectable
7) PWM constant current control (self oscillation)
8) Built-in spike noise cancel function (external noise filter is unnecessary)
9) FULL STEP & HALF STEP (two kinds), applicable to QUARTER STEP
10) Applicable to the μSTEP drive
11) Current decay mode switching function (linearly variable FAST/SLOW DECAY ratio)
12) Normal rotation & reverse rotation switching function
13) Power save function
14) Built-in logic input pull-down resistor
15) Power-on reset function
16) Thermal shutdown circuit (TSD)
17) Over current protection circuit (OCP)
18) Under voltage lock out circuit (UVLO)
19) Over voltage lock out circuit (OVLO)
20) Malfunction prevention at the time of no applied power supply (Ghost Supply Prevention)
21) Electrostatic discharge: 6kV (HBM specification)
22) Adjacent pins short protection
23) Inverted mounting protection
24) Microminiature, ultra-thin and high heat-radiation (exposed metal type) HTSSOP package (BD6387EFV/BD6385EFV/BD6383EFV)
25) FIN heat-radiating type HSOP package (BD6389FM)
26) Pin-compatible line-up (BD6387EFV/BD6385EFV/BD6383EFV or BD6389FM)
