PCA9701; PCA9702

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

Rev. 05 — 11 November 2009

Product data sheet

1. General description

The PCA9701/PCA9702 are low power 18 V tolerant SPI General Purpose Input (GPI)

shift register designed to monitor the status of switch inputs. It generates an interrupt

when one or more of the switch inputs change state. The input level is recognized as a

HIGH when it is greater than 0.7 × V_DDand as a LOW when it is less than 0.4 × V_DD

(minimum threshold of 2 V at 5 V node). The PCA9701 can monitor up to 16 switch inputs

and the PCA9702 can monitor up to 8 switch inputs.

The falling edge of the CS pin samples the input port status and clears the interrupt. When

CS is LOW, the rising edge of the SCLK loads the shift register and shifts the value out of

the shift register. The serial input is sampled on the falling edge of SCLK.

Each of the input ports has a 18 V breakdown ESD protection circuit. When used with a

series resistor (minimum 100 kΩ), the input can connect to a 12 V battery and support

double battery, reverse battery, 27 V jump start and 40 V load dump conditions in

automotive applications. Higher voltages can be tolerated on the inputs depending on the

series resistor used to limit the input current.

With both the high breakdown voltage and high ESD, these devices are useful for both

automotive (AEC-Q100 compliance available) and mobile applications.

The PCA9703/PCA9704 are new pin compatible devices for the PCA9701/PCA9702

which have an interrupt masking feature allowing selected inputs to not generate

interrupts and provides higher ground offset of 0.55 × V_DD(minimum of 2.5 V at 5 V node)

with minimum hysteresis of 0.05 × V_DD(minimum of 225 mV at 5 V node).
