MCZ33972AEW 33972 SPI advanced input-output interface controller

The 33972 IC is an advanced input/output (I/O) interface controller mainly used in the automotive industry to manage various electronic devices in vehicles.

Characteristics and functions of the 33972 chip:

Number of inputs/outputs: The chip has 22 digital inputs, each of which can be configured as a digital input or an input for analogue signals.

Analogue signal handling: The chip can process analogue signals, thanks to the built-in analogue multiplexer, which can send selected signals to an external analogue-to-digital converter (ADC).

Protection and diagnostics:

Surge protection: The circuit is equipped with surge protection on each input/output.
Thermal protection: Built-in overheating protection.
Diagnostics: Short-circuits, interrupts and fault conditions can be diagnosed.

Communication interface: The circuit uses the SPI (Serial Peripheral Interface) bus to communicate with the microprocessor. This allows it to be controlled by a variety of microcontrollers, providing flexibility in system design.

Voltage range: Operating over a wide range of supply voltages, making it suitable for a variety of vehicle applications where voltages can fluctuate.
Power-saving modes: The chip features power-saving functions, which are crucial in automotive applications to minimise current consumption when the vehicle is idle.
