Relative Integrated Pressure Sensor
7 Unique Features
Diagnostic Limits
Diagnostic of broken sensor: The output will be forced to ground (or a very low level) when the sensor
membrane breaks.
Diagnostic of broken wires: The output will be forced to ground (or a very low level) when the supply wire
breaks, even when a pull-up is still connected to the output pin.
The output will be forced to the supply voltage (or a very high level) when the ground wire breaks, even when
a pull-down is still connected to the output pin.
Output Protection
The output is protected against short-circuits at either battery terminals. The output can handle voltages
between -0.5V and 16V (independent of supply voltage).
Memlock Function
The memory consists of ZAP cells. When all calibration parameters are programmed, the chip can be locked.
This to avoid unwanted that data be written into the memory cells.
Once the chip is locked in a normal application, we can not read the zap contents and it is not possible to
unlock afterwards, unless the MOW pin is used. This can be done by apply a supply between 2.5V and 3.5V
on the MOW pin, then we can read back the content of the memory cells and zap another cell if necessary.
Clamping Levels
The user can enable the clamping of the output to ensure that the output can not enter the fault band in
normal application.
8 Application Information
47nF
47nF
Very few off-chip components are needed (only 2 decoupling capacitors, not higher than 100 nF).
Only 3 pins are used (Vdd, Vss, Out), see pad layout drawing in paragraph 9.
Calibration and Programming is made through the OUT pin.
