NXP Semiconductors MPXHZ6400A6T1

Overview

MPXHZ6400A6T1 from NXP is an absolute pressure sensor with 20–400 kPa range, ratiometric analog output (0.133–4.866 V at 5 V supply), ±1.5% full-scale accuracy over 0–85 °C, and integrated temperature compensation from −40 to +125 °C. It serves as a calibrated, signal-conditioned transducer in fuel-injected engine control units for LPG/CNG vehicles.

For engineers reviewing the MPXHZ6400A6T1 datasheet, MPXHZ6400A6T1 pinout, MPXHZ6400A6T1 application, or MPXHZ6400A6T1 equivalent, key selection criteria include absolute pressure sensing capability, SSOP-8 media-resistant packaging, fluorosilicone gel isolation for harsh environments, and compatibility with microcontroller ADC interfaces requiring stable 5 V excitation.

Technical Context

The MPXHZ6400A6T1 integrates a piezoresistive silicon diaphragm with on-chip bipolar op amp circuitry and thin-film resistor networks to deliver a high-level analog voltage output proportional to applied absolute pressure. Its transfer function is defined as VOUT = VS × (0.002421 × P – 0.00842), with temperature-dependent error scaling factors applied across −40 to +125 °C.

It features internal temperature compensation using dedicated thin-film networks and gain-stage calibration, enabling ±0.25% VFSS offset stability after 1000 pressure/temperature cycles. The sealed vacuum reference cavity and stainless steel cap ensure stable absolute pressure measurement, while fluorosilicone gel protects wire bonds and die surface without impeding pressure transmission.

FAQ

What is the pressure range and output type of the MPXHZ6400A6T1?

The MPXHZ6400A6T1 is an absolute pressure sensor with a specified range of 20 to 400 kPa. Its output is a ratiometric analog voltage spanning 0.133 V to 4.866 V at a 5.0 V supply, directly proportional to applied pressure per the transfer function VOUT = VS × (0.002421 × P – 0.00842). This makes the MPXHZ6400A6T1 suitable for precise engine load sensing without external amplification.

Does the MPXHZ6400A6T1 require external calibration or temperature compensation?

No, the MPXHZ6400A6T1 does not require external calibration or temperature compensation. It integrates on-chip bipolar op amp circuitry and thin-film resistor networks that provide full factory calibration and temperature compensation from −40 to +125 °C. The MPXHZ6400A6T1 delivers ±1.5% full-scale span accuracy over 0–85 °C without user intervention, enabling plug-and-play integration into engine control units.

What package type and pin configuration does the MPXHZ6400A6T1 use?

The MPXHZ6400A6T1 uses the super small outline package (SSOP-8), case number 98ARH99066A - a thermoplastic surface-mount housing with fluorosilicone gel isolation and stainless steel cap. It has eight pins: Pin 1 (DNC, chamfered corner), Pin 2 (VS), Pin 3 (GND), Pin 4 (VOUT), and Pins 5–8 (all DNC). The MPXHZ6400A6T1 requires no external connections to DNC pins.

Is the MPXHZ6400A6T1 suitable for LPG or CNG fuel systems?

Yes, the MPXHZ6400A6T1 is explicitly designed for LPG and CNG applications. Its fluorosilicone gel isolation, media-resistant packaging (case 98ARH99066A), and porting options enable safe, long-term operation with hydrocarbon vapors. The MPXHZ6400A6T1's qualification with dry air as pressure media - plus factory guidance on alternate media compatibility - supports its use in certified bi-fuel vehicle systems.

What is the response time and warm-up time specification for the MPXHZ6400A6T1?

The MPXHZ6400A6T1 has a response time of 1.0 ms (10–90% of final output) to step pressure changes, and a warm-up time of 20 ms - defined as the time required to meet specified output voltage after pressure stabilization. These values ensure the MPXHZ6400A6T1 supports real-time combustion cycle monitoring and rapid system initialization in engine control applications.
