LM74500QDDFRQ1 +BOM

Reverse polarity protection controller

LM74500QDDFRQ1 Allgemeine Beschreibung

Equipped with a charge pump gate drive for an external N-channel MOSFET, the LM74500-Q1 simplifies system designs by providing a robust solution for reverse polarity protection. This feature is particularly advantageous for automotive ISO7637 compliance, ensuring optimal performance in harsh operating conditions. Additionally, the controller's low power consumption when in sleep mode, drawing only around 1 µA of current with the enable pin low, enhances overall system efficiency

V napájení 1,2V je s tímto IC 2,6V... Musel jsem upravit dělič abych se dostal na správné napětí.The 1.2V supply is with this IC 2.6V ... I had to adjust the divider to get the correct voltage.
