MPL115A

Digital barometric pressure sensor

Overview

Freescale Semiconductor’s MPL115A series is

a simple barometer with digital output (I2C/SPI)

for cost-sensitive applications. A MEMS

pressure sensor with a conditioning IC provides

accurate pressure measurement. The MPL115A

is offered in a 5 x 3 x 1.2 mm LGA package for

space constrained applications. This surface

mount package is RoHS-compliant. The

MPL115A is ideal for battery and solar powered

applications with its low current consumption

at 1 μA in sleep mode and 5 μA in active mode.

The MPL115A enables altitude detection, weather

changes and will increase data capacity in

hard disk drives as well as providing absolute

pressure measurement for industrial equipment.

Target Applications

• Barometry (portable and desk-top)

• Altimeter

• Weather stations

• Hard disk drives (HDD)

• Health monitoring

• Cooling fan control

• Dead reckoning assistance

• GPS navigation assistance

• Wound management

• Security and safety

• Ambient pressure switch

• Leak detection

• Vacuum equipment
