NXP Semiconductors MP3H6115A6T1

Overview

MP3H6115A6T1 from Freescale Semiconductor is an absolute pressure sensor with 15–115 kPa range, ratiometric analog output (2.7–3.3 V supply), ±1.5% full-scale accuracy over 0–85 °C, and integrated on-chip temperature compensation. It delivers a high-level voltage output (0.079–2.861 V) proportional to applied pressure and is designed for engine manifold absolute pressure (MAP) sensing in automotive control systems.

For engineers reviewing the MP3H6115A6T1 datasheet, MP3H6115A6T1 pinout, MP3H6115A6T1 application, or MP3H6115A6T1 equivalent, key selection criteria include its absolute pressure range, ratiometric transfer function (V_OUT = V_S × (0.009×P – 0.095)), 1 ms response time, and SSOP-8 package compatibility with surface-mount reflow processes.

Technical Context

The MP3H6115A6T1 integrates a piezoresistive silicon diaphragm with thin-film resistor networks and bipolar op-amp circuitry to deliver signal-conditioned analog output. Its on-chip temperature compensation operates across –40 °C to +125 °C, while calibration ensures stable offset and span over temperature.

This monolithic sensor uses fluorosilicone gel encapsulation and a sealed vacuum reference cavity to enable absolute pressure measurement. The ratiometric output scales linearly with supply voltage, and its transfer function is defined by fixed coefficients (0.009 mV/kPa gain, –0.095 V offset at 3.0 V_S).

FAQ

What is the pressure reference type of the MP3H6115A6T1?

The MP3H6115A6T1 is an absolute pressure sensor with a sealed vacuum reference cavity. This means its output reflects pressure relative to perfect vacuum, not ambient atmospheric pressure. The MP3H6115A6T1 is therefore suitable for applications like MAP sensing and altimetry where barometric drift must be eliminated - unlike gauge or differential sensors that require external reference ports or venting.

Does the MP3H6115A6T1 require external calibration or trimming?

No, the MP3H6115A6T1 features factory-calibrated on-chip temperature compensation and a fixed ratiometric transfer function (V_OUT = V_S × (0.009×P – 0.095)). Its ±1.5% VFSS accuracy over 0–85 °C is achieved without user calibration. External trimming or software compensation is unnecessary unless system-level accuracy tighter than 1.5% is required - in which case, two-point calibration using known pressure points may be applied.

What is the maximum supply voltage the MP3H6115A6T1 can tolerate?

The MP3H6115A6T1 has an absolute maximum supply voltage of 3.3 V DC, with recommended operation between 2.7 V and 3.3 V. Exceeding 3.3 V risks permanent damage, as specified in Table 2 of the datasheet. Its ratiometric behavior means output scales linearly with supply voltage - so maintaining tight regulation within this window ensures consistent ADC conversion results across varying power rail conditions.

Can the MP3H6115A6T1 be used with a 5 V microcontroller ADC?

Yes, but only if the MP3H6115A6T1 is powered from a regulated 3.3 V supply - not 5 V. Its output spans up to 2.861 V at 3.0 V supply, safely within most 3.3 V-tolerant ADC input ranges. Direct connection to a 5 V ADC input is acceptable only if the ADC accepts 3.3 V logic levels; otherwise, a resistive divider or level-shifter is required to avoid exceeding the ADC's absolute maximum input voltage.

Is the MP3H6115A6T1 compatible with lead-free reflow soldering processes?

Yes, the MP3H6115A6T1 is qualified for lead-free reflow soldering per J-STD-020. Its Case 98ARH99066A package supports peak reflow temperatures up to 260 °C. The recommended footprint (Figure 9) and thermal profile ensure reliable solder joint formation without delamination or package cracking - critical for automotive and industrial applications requiring high manufacturing yield and long-term mechanical integrity.
