BD6387EFV-E2 ROHM

Stepping Motor Driver series High Performance, High Reliability 36V Stepping Motor Driver Series No.12009EAT04 BD6383EFV, BD6385EFV, BD6387EFV, BD6389FM 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 ICs generation of heat by adopting low-ON resistance DMOS and high heat-radiation power package. As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supplys rated voltage of 36V and rated output current of 1.0A2.2A. For the input interface, the CLK-IN drive mode and the parallel IN drive mode are compatible with each other, so please choose an input mode according to needs of application. There are excitation modes of FULL STEP & HALF STEP (2 kinds), QUARTER STEP mode, and for current decay mode, the ratio of FAST DECAY & SLOW DECAY can be freely set, so the optimum control conditions for every motor can be realized. In addition, being able to drive with one system of power supply makes contribution to the set designs getting easy. 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 motorDC 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 STEP 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) 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. www.rohm.com 2012.02 - Rev.A 1/8 2012 ROHM Co., Ltd.
