PCA9703
18 V tolerant SPI 16-bit GPI with maskable INT
8.2.2 Application examples including switches to battery
9. Limiting values
[1] With GPI external series resistors, the inputs support double battery, reverse battery and load dump conditions. During double battery or
load dump the input pin will drain slightly higher leakage current until the input drops to 18 V. For more detail of leakage current
specification, please refer to Table 5 “
Static characteristics”. See Section 7.4 for series resistor requirements.
