特点：
- rated output current（dc）1.5a
- low on resistance dmos output
- clk-in drive mode
- pwm constant current(other oscillation)built-in spike noise cancel function
(external noise filter is unnecessary) - full-, half(two kinds)-, quarter-step functionality
- freely timing excitation mode switch
- current decay mode switch
(linearly variable fast/slow decay ratio) - normal rotation & reverse rotation
switching function - power save function
- built-in logic input pull-down resistor
- power-on reset function
- thermal shutdown circuit(tsd)
- over-current protection circuit（ocp）
- under voltage lock out circuit(uvlo)
- over voltage lock out circuit(ovlo)
- ghost supply prevention(protects against
malfunction when power supply is disconnected) - adjacent pins short protection
- microminiature, ultra-thin and high heat-radiation

- evaluation board - bd63715aefv-evk-001
this evaluation board is a board for driving the stepping motor with a rohm's stepping motor driver bd63715aefv. motor drive and driver the motor can be driven by vcc for power supply and 5v power supply for control signal. drive / stop and excitation modes can be set with an external switch. the input interface adopts the clk-in drive system, and the excitation mode supports full step, half step, quater step, 1/8 step, and 1/16 step mode by the built-in dac.
