Overview

The LM74610-SQEVM evaluation module demostrates reverse polarity protection as a replacement of Schottkey Diodes and P-Channel MOSFETs. In this reverse polarity protection solution the LM74610 Smart Diode Controller is used to provide a gate drive for 40V (VDS) external N-Channel MOSFET. The LM74610-SQEVM emulates an ideal diode properties when connected in series with a power supply. When a negative voltage is senced at the Input, the LM74610 pulls down the MOSFET gate and isolates the connected load from the power supply. The TVS voltage clamping diodes D1_1 and D1_2 make LM74610-SQEVM safe for ISO7637 transient pulse testing.
