Description
The MCZ33972ATEW is a multiple switch detection interface designed to detect the closing and opening of up to 22 switch contacts. It features a serial peripheral interface (SPI) that transfers the switch status to a microprocessor unit (MCU). Additionally, it includes a 22-to-1 analog multiplexer for reading inputs as analog, with the buffered analog input signal provided on the AMUX output pin for the MCU to read.
Specifications and features
- Designed to operate within a voltage range of 5.5 V to 26 V
- Switch input voltage range: -14 V to VPWR, with a maximum of 40 V
- Interfaces directly to MPU using 3.3 V/5.0 V SPI protocol
- Selectable wake-up on change of state
- Selectable wetting current (16 or 2.0 mA)
- 8 programmable inputs for switches to battery or ground
- 14 switch-to-ground inputs
- Typical standby current: VPWR = 100 μA and VDD = 20 μA
- Active interrupt (INT) on change-of-switch state
Application Scenarios
The MCZ33972ATEW is suitable for various applications that require the detection of switch contacts, such as automotive systems, industrial control systems, and consumer electronics.
