Overview
Power Management IC Series for Automotive Body Control Regulator with Voltage Detector IC BD3951F No.
09039EAT05 ●Description BD3951F is a 5V LDO system regulator particularly developed for automotive applications.
The output current of the regulator can be drawn up to 150mA, and it has built-in power-on reset and input voltage sense.
This device can withstand 50V surge input voltage as well as wide ambient temperature operations from -40℃ to +125℃.
The adjustable reset delay time and detection input voltage allow to meet with wide range of design requirements.
●Features 1) Micro processor power supply 5.
0V, Adjustable Reset, Adjustable Comparator.
2) 5V is Pch DMOS type low drop out voltage regulator.
Iomax=150mA.
3) Low ESR capacitor (Ceramic Capacitor) is available for the Output Capacitor.
4) Over Current Protection built in to prevent the destruction of IC.
5) Thermal Shut Down is built in to prevent the heat runaway.
6) VCC absolute Maximum Ratings 36V.
7) Vcc peak input voltage 50V (*1) 8) Small surface mount package SOP8.
●Applications Automotive application (Rain Sensor and Cluster Panel etc.
) and all other electronics application.
