Description
BD63860EFV is a high-grade stepping motor driver with an internal 3-bit DAC, designed to drive bipolar stepping motors in eighth-step modes. The IC features several integrated protection circuits and achieves excellent thermal dissipation performance due to its low ON-resistance DMOS output transistors and high-dissipation power package.

FEATUREs
1) Single power supply input (Vin max. 36 V)
2) Rated output current: 2.5 A (peak)
3) Low ON-resistance DMOS output (0.8 Ω total across upper + lower FETs)
4) Serial/CLK-IN drive mode (integrated translator circuit)
5) PWM constant-current control (fixed chopping frequency)
6) Built-in spike noise cancel function (external noise filter is unnecessary)
7) Full-, half-, quarter- and eighth-step functionality
8) AUTO decay mode
9) Current decay mode switching function (linearly variable fast/slow decay ratio)
10) Normal rotation & reverse rotation switching function
11) Power-save function
12) Built-in logic input pull-down resistor
13) Power-on reset function
14) Thermal shutdown circuit (TSD)
15) Over-current protection circuit (OCP)
16) Under-voltage lockout circuit (UVLO)
17) Over-voltage lockout circuit (OVLO)
18) Ghost Supply Prevention (protects against malfunction when power supply is disconnected)
19) Micro-miniature, ultra-thin and high heat-radiation (exposed metal type) HTSSOP package

APPLICATIONs
   Laser printers, multi-function printers, inkjet printers, scanners, mini printers, PPCs, photo printers, etc.
