Product Overview

The KIT33975AEWEVBE is an evaluation kit for MC33975 a multiple switch detection interface with suppressed wake up. The MC33975 device has two modes of operation, normal and sleep. Normal mode allows programming of the device and supplies switch contacts with pull up or pull down current as it monitors the switch change of state. The sleep mode provides low quiescent current, which makes the MC33975 ideal for automotive and industrial products requiring low sleep state currents. Improvements are a programmable interrupt timer for sleep mode that can be disabled, switch detection currents of 32mA and 4.0mA for switch to ground inputs, and an interrupt bit that can be reset. This kit is designed to detect the closing and opening of up to 22 switch contacts. The switch status, either open or closed, is transferred to the microprocessor unit (MCU) through a serial peripheral interface (SPI). The device also features a 22 to 1 analog multiplexer for reading inputs as analog.
  • Designed to operate from 5.5V ≤ VPWR ≤ 28V
