1.1 Introduction

In this design scheme, the LM74704-Q1 is combined with a MOSFET and used in series with a battery as a replacement for a Schottky diode and PFET, in reverse-polarity protection circuitry as shown in Figure 3-1. For more information on the LM74704-Q1 functional and electrical characteristics, see LM74703-Q1, LM74704-Q1 Ideal Diode Controller with External FET Health Indication.
