CD1030 - 33-channel multiple switch detection interface

Datasheet Summary

Description

The CD1030 is designed to detect the closing and opening of up to 33 switch contacts.

The switch status, either open or closed, is transferred to the microprocessor unit (MCU) through a serial peripheral interface (SPI).

Features

Fully functional operation from 4.5 V to 36 V.
Full parametric operation from 6.0 V to 28 V.
Low-power mode current IBATP = 50 μA and IDDQ = 10 μA.
33 switch detection channels.
21 switch-to-Ground (SG) inputs with configurable pull-up current sources.
12 programmable switch (SP) inputs.
Switch-to-Ground (SG) or Switch-to-Battery (SB).
Operating switch input voltage range from -1.0 V to 36 V.
Selectable wetting cur.

CD1030 33-channel multiple switch detection interface with programmable wetting current Rev. 6.0 — 20 August 2024 Product data sheet 1 General description The CD1030 is designed to detect the closing and opening of up to 33 switch contacts. The switch status, either open or closed, is transferred to the microprocessor unit (MCU) through a serial peripheral interface (SPI). This SMARTMOS device also features a 35-to-1 analog multiplexer for reading the input channels as analog inputs. The analog selected input signal is buffered and provided on the AMUX output pin for the MCU to read. Independent programmable wetting currents are available as needed for the application. A battery and temperature monitor are included in the IC and available via the AMUX pin.
