Product details
Overview
MC33816MAER2 from NXP Semiconductors is a programmable SMARTMOS solenoid controller IC for precision engine valve and injector control. It integrates five high-side and seven low-side MOSFET pre-drivers, four independent microcores, dual voltage regulators (5 V and 7 V), four current-sense modules, VDS monitoring, and SPI-based fault annunciation. It operates across 5.0–32 V battery input and supports up to 72 V pre-drive voltage in automotive powertrain applications.
For engineers reviewing the MC33816MAER2 datasheet, MC33816MAER2 pinout, MC33816MAER2 application, or MC33816MAER2 equivalent, this page delivers verified technical context, exact pin functions, real-world solenoid control use cases, confirmed alternative parts with functional distinctions, and supply-chain support for production deployment in diesel/gasoline direct injection systems.
Technical Context
The MC33816MAER2 implements a deterministic, multi-microcore architecture: two logic channels-each with two concurrent microcores-execute 93 instruction-set microcode for gate timing, diagnosis, and protection. Each channel has dedicated Code RAM and Data RAM banks, enabling parallel real-time control of high-side (HS1–HS5) and low-side (LS1–LS7) drivers.
It features integrated charge pumps per high-side driver (100% duty cycle capable), a high-voltage DC-DC converter for LS7, VDS monitoring with eight selectable thresholds, and four differential current-sense inputs (VSENSEN1–4 / VSENSEP1–4) supporting both solenoid and DC-DC current measurement with SPI-accessible diagnostics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33814AE | Four high-side + six low-side pre-drivers; no DC-DC converter; no EOI measurement; lower VBOOST max (60 V) | Targeted at simpler single-injector or non-DI applications; lacks G_LS7 and VSENSEP4/VSENSEN4 for DC-DC current sensing | Select when system requires fewer drivers, lower cost, and no DC-DC conversion-ideal for throttle or EGR valve control. |
| TPIC46L01QPWPRQ1 | Single high-side driver with integrated current sense; no microcore; fixed slew rate; SPI-less analog output | Designed for basic on/off solenoid control-not for multi-event, closed-loop, or multi-channel timing-critical applications | Choose only for auxiliary low-complexity loads where deterministic timing, diagnostics, and multi-channel coordination are not required. |
Compared with MC33816MAER2, MC33814AE offers reduced channel count and no DC-DC capability but shares core diagnostics and microcode architecture; TPIC46L01QPWPRQ1 provides minimal integration for cost-sensitive point-control, lacking programmability, multi-channel synchronization, and safety-certified firmware execution.

FAQ
What is the maximum operating voltage for the high-side pre-drivers in MC33816MAER2?
The MC33816MAER2 high-side pre-drivers support up to 72 V on the VBOOST pin under steady-state conditions, enabling direct control of high-voltage solenoids in 24 V commercial vehicle systems. This rating is validated per Table 3 (Maximum Ratings) in the official NXP datasheet Rev. 10.0, and applies to all five high-side channels (G_HS1–G_HS5) with corresponding bootstrap (B_HS1–B_HS5) and source monitor (S_HS1–S_HS5) pins.
Does MC33816MAER2 support End-of-Injection (EOI) measurement?
Yes, MC33816MAER2 supports programmable End-of-Injection (EOI) measurement as part of its MC33816MAE variant functionality. This feature is implemented in hardware and accessible via microcode instructions, allowing precise timing capture of solenoid de-energization for closed-loop fuel calibration-confirmed in Section 6.9 of the datasheet Rev. 10.0.
How many current sense inputs does MC33816MAER2 provide, and what is their voltage range?
MC33816MAER2 provides four differential current sense input pairs: VSENSEN1/VSENSEP1, VSENSEN2/VSENSEP2, VSENSEN3/VSENSEP3, and VSENSEN4/VSENSEP4. Each pair supports a dynamic common-mode range of ±15 V for ≤1.0 µs pulses, and ±5.0 V for longer durations-enabling accurate shunt-based current measurement across solenoids and the DC-DC converter stage.
What is the role of G_LS7 in MC33816MAER2, and how does it differ from G_LS1–G_LS6?
G_LS7 in MC33816MAER2 is the dedicated low-side gate driver for the internal high-voltage DC-DC converter, whereas G_LS1–G_LS6 drive external solenoid loads. G_LS7 operates with distinct timing, current capability, and fault-handling logic optimized for DC-DC switching-documented in Section 6.4 and Figure 2 of the datasheet Rev. 10.0 as part of the "DC-DC converter" functional block.
Is MC33816MAER2 qualified for automotive applications, and what is its temperature grade?
Yes, MC33816MAER2 is AEC-Q100 qualified for automotive use and rated for –40 °C to +125 °C ambient operating temperature (Grade 1). Its thermal resistance (RθJA) is 27 °C/W on a 4-layer FR4 PCB with exposed pad vias, and it includes integrated overtemperature protection-verified in Sections 4.2 and 4.3 of the NXP datasheet Rev. 10.0.
