SGMCD1020Q
自動車グレード22-Channel Multiple Switch Detection Interface for Automotive Applications
The SGMCD1020Q 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 22 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 22-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.
The SGMCD1020Q 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 SGMCD1020Q is available in a Green TQFN-5×5-32GL package. It operates over the junction temperature range of -40℃ to +125℃.
