1ch Low Side Switch IC
In-Vehicle 1ch Low Side Switch
BD1LB500 Series (BD1LB500EFJ-C BD1LBU50EFJ-C BD1LB500FVM-C)
Features ■ Built-in overcurrent limiting circuit ■ Built-in thermal shutdown circuit (TSD) ■ Built-in open load detection circuit (at output OFF) ■ Enables direct control from
CMOS logic ICs, etc. ■ Low standby current ■ Built-in under
voltage lock out circuit ■ Built-in diagnostic output (ST) terminal ■ Low ON resistance RDS(ON)=350mΩ(Typ) (VDD=IN=5V, Ta=25°C, IOUT=0.25A) ■ Built-in over
voltage protection(active clamp) for output circuit ■ Monolithic power IC in which the control unit (
CMOS) and power MOS FET are incorporated into one chip ■ 1ch low side switch for driving mechanical relay coil ■ AEC-Q100 Qualified(1)
(1) Grade1
Overview BD1LB500 Series is an in-vehicle 1ch low side switch. This switch builds in the overcurrent limiting circuit, thermal shutdown circuit, open load detection circuit and under
voltage lock out circuit. It also provides the diagnostic output circuit when an abnormality is detected.
Application ■ In-vehicle application (Air conditioners, body devices, meters, etc.)
