特点：
- rated output current (dc) 2.0a
- low on resistance dmos output
- clk-in and para-in drive mode
- pwm constant current (other oscillation)
- built-in spike noise cancel function
(external noise filter is unnecessary) - full (two kinds)-, half (three kinds)-, quarter (two kinds)-, 1/8-, 1/16-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 (exposed metal type) package
