Introduction:

The TWS532 is a new generation of high resolution pressure sensor from Tide Win Technology, Inc. Support both I2C Bus and analog output interface. The sensor module includes a high linearity pressure sensor with internal factory calibrated coefficients. It provides a precise digital pressure output up to 14 bits and adjustable conversion speed. Small dimension of only 10.0 mm X 10.0mm and height of only 9.5mm allow for integration devices. Complete reference design for pressure meter.

 

Features:

l   Gauge type pressure measurement

l   Span: Normal 0~100 PSI ( 0.7 MPa or 700KPa)

l   Industrial pressure measurement application

l   Integrated Temperature Sensor for temperature compensation

l   Span and offset calibrated, simplify host MCU program loading

l   Minimal external component requirements for pressure meter design

l   Support circuit configuration of PNP or NPN switch driving method and Current or Voltage analog output mode, idea designed for pressure switch

l   Optional TWC532E/C(*Note1) display controller, support pressure switch function and several pressure units for display, minimal product time to market

l   Power for Circuit (VDD):　2.7~5.5V or 5~35V(with external Transistor)

l   Operating temperature range: 0~50℃

Note1:  TWC532E for 7-segments LED display, TWC532C for LCD display controller.

 

Applications:

l   Pressure System

l   Industry/Medical System
