SLVSFQ6A November 2020 – June 2021 TPS2640
PRODUCTION DATA
To protect the electronic systems from reverse input supply due to miswiring, often a power component like a schottky diode is added in series with the supply line as shown in Figure 9-4. These additional discretes result in a lossy and bulky protection solution. The TPS26400 devices feature fully integrated reverse input supply protection and does not need an additional diode. These devices can withstand –42 V reverse voltage without damage. Figure 9-5 illustrates the reverse input polarity protection functionality.
