14. Protection and Diagnostics

14.1

I/O Protection

In order to meet the requirements for over-voltage and reverse-polarity protection on both the output and power

supply pins, the IPS2200 includes several protection and diagnosis features:

1.

Protection against short circuit of the output pins SIN, SINN, COS, and COSN to GND or to VDD

2.

Over-voltage and reverse-polarity protection:

a.

On supply pin VDD to GND

b.

On analog output pins SIN, SINN, COS, and COSN to GND

c.

On digital output pins SIO_SDA, CSN_IRQN, and SCK_SCL to GND

15. Programming Options

The IPS2200 family offers a variety of programming options. The IC is programmed through the digital bi-

directional SPI or I2C interface. The main programming functions are described in Table 22.

15.1

Lock Feature (Cyber Security)

The IPS2200 contains a write lock bit option, which can be set by the user. Once the write lock bit is set, no

further writing to the chip is possible.

Note: For programming details, see the IPS2200 Programming Guide, which is available from Renesas on

request.
