TPMS FAMILY
TARGET APPLICATIONS
• Tire pressure monitoring systems
• Ultra-low-power wireless sensing
IMPLEMENTATIONS
• Measures dual-axis acceleration to support location of
wheel on the vehicle
• Measures temperature
• Measures battery voltage
• Bi-directional wireless communication
• Measures tire pressure for passenger, light-duly or heavy-
duty vehicles
NXP TPMS SENSORS
NXP’s tire pressure monitoring sensors (TPMS) has a fully
integrated 4 x 4 mm and 7 x 7 mm package footprint.
These are significantly smaller than the previous generation
of QFN packages on the market.
These devices provide:
• Low transmitting power consumption (less than 7 mA Idd)
• Large customer memory size (~8-15 kB)
• Dual-axis accelerometer architecture
NXP’S TPMS SOLUTION INTEGRATES:
• 8-bit MCU
• Pressure sensor
• XZ-axis or Z-axis accelerometer
• 125 kHz LF receiver
• 315–434 MHz RF transmitter
NXP’s portfolio can support cars, light and heavy trucks as
well as buses. These TPMS markets are mainly regulation
driven with new mandates, resulting in significant growth.
NXP continues to produce TPMS products that meet the
latest mandates to accommodate customer requirements.
