Description
The MCZ33972AEW is an SOIC, which is a surface mounted integrated circuits. The IC is a multiple switch detection interface coming with wake - up function. Generally, it is designed to discover the opening and the closing of the maximum 22 contacts of switches. Further, it sends the switch status (Open or Closed) to the microprocessor unit (MCU) with the help of a SPI ( Serial Peripheral Interface ). The device can read input as an analog using 22 to1 multiplexer. The MCZ33972AEW offers two modes for its working namely normal and sleep. Here, the normal mode deals with the programming task and sends switch contacts with either pull-up or pull-down current as it monitors switch changes its state.
While on the other hand the sleep mode provides low passive current, which makes the IC ideal for the automotive products which requires low sleep current. The MCZ33972EWR2 can be used as a replacement for this device. The IC is surface mounted on the PCB. The IC is manufactured in the package of 32 SOICW .
Pin-out
As mentioned earlier these IC comes in 32 SOICW package , as the name suggest the IC consist of total 32 pins.
Features
● Operating voltage range : -5.5V to 26V
● Switch input voltage range : -14V to maximum 40V
● It consists of total 8 programmable inputs
● Selectable wake up on change of state
● It comes with a 14 switch to ground inputs
● Lead free packaging
● Has a standby current of 100μA for VPWR, while 20μA for VDD
● Design consist of exposed pad packaging.
● The temperature range of the IC is between -40℃ to 125℃
Applications
The feature of this device allows it to be used in variety of applications and projects. Some of the major uses of these IC is in Sensor power Supply, Switch monitor, Led driver, module system, etc. Below is the circuit of application of these device in the sensor power system.
Many sensors such as temperatures sensors or pressure sensors requires a power supply voltage to power them and get them working. The above figure shows how the IC can be used as an supply power for the sensors.
