PCA9701; PCA9702

18 V tolerant SPI 16-bit/8-bit GPI with INT

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 7.3 for series resistor requirements.

n = 15 for PCA9701; n = 7 for PCA9702.

Limiting values

In accordance with the Absolute Maximum Rating System (IEC 60134).
