Overview
Datasheet 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 overvoltage 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.

(3) It is necessary to detect unusual state(ST terminal is low) when VDD terminal is opened.
When ST pin is not used, it can be open.
