Summary

ICS1531 Data Sheet - Preliminary

2.9

Industry-Standard 2-Wire Serial Interface

To access all its registers, the ICS1531 uses an industry-standard 2-wire serial interface that operates at

one of the following speeds:

• A low speed of 100 kHz

• A high speed of 400 kHz

• An ultra speed of 800 kHz

For use with the 2-wire serial interface, the ICS1531 has 5 V-tolerant inputs. The ICS1531 can use either

of two unique, alternative sets of addresses. Table 2-2 lists the addresses that can be used, depending on

the state of the SBADR pin.

Programmable Outputs

For general-purpose outputs, the ICS1531 provides three programmable pins, PSEL3, PSEL2, PSEL1

(Reg 37:2-0).
