MC33816AE Présentation
A solenoid controller IC (also called an SD6 programmable solenoid driver) is a specialized power-management device that sits between an ECU/microprocessor and the external N-channel MOSFETs that actually switch current through fuel-rail or transmission solenoids. In the broader taxonomy, the MC33816AE is a gate driver -> power management IC -> semiconductor. It combines a charge-pump boost supply for high-side gate drive, built-in bootstrap diodes and half-bridge structures, current-sense amplifiers, and configurable peak-and-hold solenoid current profiles, so it replaces what would otherwise require an FPGA, op-amps, and discrete drivers.
Key features include charge-pump boost, integrated bootstrap diodes for the high-side stages, configurable peak-and-hold solenoid current profiles, eight configurable pre-drivers (5 HS + 7 LS), SPI communication for ECU command and diagnostic telemetry, and built-in overcurrent/short-to-battery/short-to-ground protection. The device supports Vsupply of up to 72 V transient with steady-state operation to 36 V on the battery rail, and operates over the -40 C to +125 C automotive temperature window.
Technically, the four microcores enable parallel solenoid actuation with deterministic latency, while the SPI bus (two independent ports in some configurations) supports daisy-chained multi-IC ECU architectures. The current-sense amplifier gain is programmable, allowing the same PCB to drive 1 A and 20 A solenoid loads by changing only firmware.
Typical applications include gasoline direct-injection fuel injectors, diesel piezo and solenoid injectors, automatic transmission solenoids (variable force solenoids), and precision fluid-control valves in industrial automation. The automotive temperature grade and diagnostic coverage make it a fit for ISO 26262 ASIL-rated ECUs when paired with a suitable supervisor MCU.
When designing with the MC33816AE, place the charge-pump and bootstrap capacitors close to the IC pins, keep the high-current gate-drive loops area-minimized, and confirm SVP-tuned SPI/PE guarantees that firmware remains within the device's diagnostic latency budget. The LQFP-64 exposed-pad variant (where present) lowers thermal resistance; for the non-exposed-pad variant used here, copper pour on all four inner rows is recommended for multi-amp continuous drive.

Applications typiques
MC33816AE convient pour 6 applications: Gasoline Direct Injection (GDI) Solenoid Control, Diesel Solenoid and Piezo Injector Drive, Automatic Transmission Variable Force Solenoids, Industrial Hydraulic Valve Control, 48 V Mild-Hybrid Solenoid Actuators, Precision Fluid Control Valves.
Gasoline Direct Injection (GDI) Solenoid Control
The MC33816AE drives external N-channel MOSFETs for high-pressure gasoline direct injectors where repeatable peak-and-hold current waveforms are mandatory. Its charge-pump boost ensures 10 V Vgs on the high-side even at 36 V VBAT cold-crank, while the four microcores manage parallel injection events. A typical 6-cylinder GDI ECU pairs the MC33816AE with an S32K MCU over SPI, achieving sub-100 us peak-current rise times and integrated short-to-battery / short-to-ground diagnostics that map directly to ASIL requirements.
Recommandé
Diesel Solenoid and Piezo Injector Drive
For diesel common-rail solenoid injectors, the MC33816AE provides the configurable high-current pulses and the precise peak-and-hold tail current needed for repeatable injection quantities. The integrated current-sense amplifier with programmable gain lets one design scale from 1 A pilot pulses to 20 A main injection events. Its -40 C to +125 C operating range and 72 V transient tolerance cover 12 V/24 V diesel architectures including commercial vehicles, while SPI diagnostics give the supervising ECU the data needed for on-board diagnostics compliance.
Recommandé
Automatic Transmission Variable Force Solenoids
The MC33816AE's eight configurable pre-drivers (5 HS + 7 LS) match the channel count of a typical 6-speed automatic transmission pressure-control manifold. Each solenoid is driven through an external MOSFET half-bridge with current feedback into the on-chip amplifier. Four microcores schedule solenoid updates with deterministic latency, which is critical for smooth shift feel. The LQFP-64 (10x10) package fits inside the transmission control module where board area is constrained.
Recommandé
Industrial Hydraulic Valve Control
Outside automotive, the MC33816AE drives proportional hydraulic valves in industrial machinery where precise current control translates to repeatable actuator positioning. The SPI-configurable current-sense gain lets the same hardware serve low-current proportional valves and high-current on/off solenoids. With 36 V steady-state supply tolerance and an exposed thermal pad-compatible PCB footprint, the IC survives 24 V industrial bus transients that would destroy a generic gate driver.
Recommandé
48 V Mild-Hybrid Solenoid Actuators
In 48 V mild-hybrid architectures, the MC33816AE's 72 V transient tolerance covers the rectified 48 V bus during load-dump events, while the 36 V continuous rating suits the steady-state rail. It drives e-actuator solenoids such as active engine-mount valves and electric turbo wastegates with the same peak-and-hold firmware used on 12 V systems. SPI telemetry over to the hybrid domain controller enables ISO 26262-relevant fault reporting.
Recommandé
Precision Fluid Control Valves
Medical and laboratory fluidics systems use the MC33816AE to actuate small solenoid valves with sub-millisecond timing accuracy. The configurable current-sense amplifier paired with peak-and-hold firmware produces the gentle ramp-and-hold profile needed for bubble-free dispensing, and the SPI interface lets a microcontroller log actuation counts for calibration. The LQFP-64 (10x10) footprint fits on compact pump-driver boards.

Principaux différenciateurs
- Eight pre-drivers managed by four microcores (vs MC33816B)
- AEC-Q100 qualified solenoid driver (vs Generic half-bridge gate driver)
- Integrated charge-pump and bootstrap diodes (vs Discrete N-channel high-side drive)
Notes de conception
Place the charge-pump flying capacitors C(CP1-CP2) and the bootstrap capacitors on each HS pre-driver within 3 mm of their respective IC pins. Use 1 uF X7R 50 V minimum for charge-pump capacitors and 100 nF X7R 25 V for bootstrap; the high-side gate-drive loop area must be minimized to keep ringing under 5 V peak. A solid ground pour tied to AGND and DGND on a single star point prevents digital switching noise from corrupting current-sense measurements.
Estimated: with four solenoid channels switching at 20 kHz into 20 A peak loads through external MOSFETs, the MC33816AE's quiescent + gate-drive loss is approximately 0.6 W; the LQFP-64 (10x10) without exposed pad has theta_JA near 50 C/W, yielding a 30 C junction rise. For continuous 6-cylinder GDI operation, dedicate at least 1 sq in of top-layer copper to the device thermal footprint and consider an external heatsink if drive duty exceeds 50 percent.
Do not leave bootstrap capacitors unpopulated on unused HS channels, as floating boot nodes can inject charge-pump ripple into VCP. Always assert RST before applying VBAT and wait at least 1 ms after RST de-assertion before issuing SPI commands - this avoids the microcore firmware hanging in a partially-initialized state. Finally, do not exceed the 72 V transient rating; even brief over-voltage events can permanently damage the gate-drive charge pump.
