BD68620EFV-E2

●General Description 

BD68620EFV is a bipolar low-consumption driver that 

driven by PWM current. Rated power supply voltage of 

the device is 36 V, and rated output current is 2.0A.

PALA-IN driving mode is adopted for input interface. In 

terms of current decay, the FAST DECAY/SLOW 

DECAY ratio may be set without any limitation, and all 

available modes may be controlled in the most 

appropriate way. In addition, the power supply may be 

driven by one single system, which simplifies the 

design. 

●Features 

■ Rated output current（DC）2.0A 

■ Low ON resistance DMOS output 

■ PALA-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 

■ Current decay mode switch 

（linearly variable FAST/SLOW DECAY ratio）

■ Power save function 

■ Built-in logic input pull-down resistor 

■ 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) 

■ Microminiature, ultra-thin and high heat-radiation
