新款电机驱动芯片~！

　　●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. This IC is rated for 36 V maximum input voltage / 2.5 A maximum output current and employs a constant-current， PWM allowing for full-， half-， quarter- and eighth-step excitation modes. Additionally， the current decay mode can be freely set to a ratio of fast and slow decay， allowing the IC to adapt to the optimum control conditions for every motor. The single-power supply configuration allows for easy design and layout in the application.
