Circuit Description
The BSP 75N is a monolithic power switch in Smart Power Technology (SPT) with a
logic level input, an open drain DMOS output stage and integrated protection functions.
It is designed for all kind of resistive and inductive loads (relays, solenoid) in automotive
and industrial applications.
Protection Functions
• Over voltage protection: An internal clamp limits the output voltage at
• Current limitation: By means of an internal current measurement the drain current is
• Over temperature and short circuit protection: This protection is based on sensing
The device is ESD protected according Human Body Model (4 kV) and load dump
protected (see Maximum Ratings).

in the linear region, so power dissipation may exceed the capability of the heatsink.
This operation leads to an increasing junction temperature until the over temperature
threshold is reached.

temperature detection. Over temperature shutdown occurs at minimum 150 °C. A
hysteresis of typ. 10 K enables an automatic restart by cooling.
