SP40+

Tire pressure sensor for Tire Pressure Monitoring Systems (TPMS)

SP40+ provides a very high level of integration and is

optimized to perform all of the functions necessary to im-

plement a state-of-the-art sensor module for Tire Pressure

Monitoring System (TPMS). With its integrated micro-

controller, sensors and convenient peripherals, the SP40+

needs the addition of only a few passive components and

a battery to complete a full TPMS module.

SP40+ measures pressure, radial acceleration, temperature

and supply voltage and is certified as a green package com-

pliant with RoHS. SP40+ comes with a pressure-auto-rang-

ing feature, providing best-in-class pressure-accuracy in the

range from 100 to 1400 kPa, making it the ideal choice for

all car types from passenger vehicle to heavy trucks.

Compared to the previous generation SP37, the SP40+

family offers even lower current consumption and more

features like larger flash, better sensor accuracy and higher

pressure range.

SP40+ fully supports all necessary

requirements for a
