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.)

(2) When the open detection function is required, an external resistance must be added between DRAIN terminal and SOURCE terminal.
(3) It is necessary to detect unusual state(ST terminal is low) when VDD terminal is opened.
