Automotive 33-Channel Multiple Switch Detection Interface with Programmable Wetting Current

SGMCD1030Q.PDF

The SGMCD1030Q provides a low-cost integrated switch detection solution. As a multiple switch detection interface (MSDI) device, it can detect the switch status of up to 33 channels and transfer the switch status information (open or closed) to the microprocessor unit (MCU) through a serial peripheral interface (SPI). In addition, the device features a 35-to-1 analog multiplexer for outputting buffered selected input analog signals to the AMUX pin so that the signal can be read by the MCU.

Several wetting current levels (2mA, 6mA, 8mA, 10mA, 12mA, 16mA and 20mA) are available to be configured, separately. Besides, this device provides the information for battery voltage and IC inner temperature, which can be read by the MCU from the AMUX pin.

The SGMCD1030Q has three modes of operation: normal mode, low-power mode (LPM) and polling mode. When the device is in normal mode, the device can be programmed and can provide the corresponding wetting current to the switch contacts as it monitors the switch status. During low-power mode, the low quiescent current makes the device ideal for applications in automotive or industrial scenarios that require low sleep state current. The polling mode periodically detects the input pins to determine their state and to determine if the state has changed from normal mode.

The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.

The SGMCD1030Q is available in a Green LQFP-7×7-48AL (Exposed Pad) package.
