Product details

Overview

MC33910G5AC from NXP Semiconductors is a LIN System Basis Chip (SBC) integrating a LIN 2.0/2.1 transceiver, dual 50 mA/60 mA high-side drivers, 5.0 V low-dropout regulator (60 mA), configurable window watchdog, and high-voltage analog/logic input (L1) for contact monitoring or wake-up - deployed in automotive body electronics such as window lift and door lock modules.

For engineers reviewing the MC33910G5AC datasheet, MC33910G5AC pinout, MC33910G5AC application, or MC33910G5AC equivalent, this page delivers verified functional identity, validated 32-pin LQFP package mapping, confirmed SPI-controlled diagnostics, LIN conformance to SAE J2602-2, and real-world automotive use-case constraints including -40 °C to +125 °C operation and ±6.0 kV ESD on LIN pin.

Technical Context

The MC33910G5AC implements a multi-mode power management architecture with Normal, Sleep, and Stop operating states - enabling ultra-low quiescent current (33 µA typical in Sleep mode at 13.5 V) while retaining LIN bus and L1 wake-up capability. Its SPI interface operates up to 4.0 MHz and provides full register-accessible diagnostics including HSx open-load, short-circuit, overtemperature, and LIN bus fault flags.

It integrates two independent high-side switches (HS1/HS2) with PWM input support, a selectable-ratio analog multiplexer feeding ADOUT0 (for L1 or VSENSE sensing), and a dedicated Hall sensor supply (HVDD) with ±2.0% matching to VDD. The LIN transceiver supports waveshaping disable for >100 kbps operation and complies with ISO 7637-2 pulse 3b immunity and J2602 conformance testing.

Pinout & Package

MC33910G5AC is housed in a 32-pin LQFP (7 mm × 7 mm, 0.8 mm pitch) with exposed thermal pad. Pin assignments follow NXP's standardized 33910 family layout; all NC pins (11, 15, 16, 17, 19, 20, 21, 22, 28, 30) must remain unconnected or grounded per datasheet guidance.

HVDD	Hall Sensor Supply	Switched 5.0 V output with ±2.0% matching to VDD; requires 1–10 µF external capacitor; powers Hall-effect position sensors in motor control.
VDD	Main Regulator Output	Primary 5.0 V supply for MCU and logic; internally regulated with fault reporting (LVR, overtemp, undervoltage); requires 2–100 µF capacitor.
WDCONF	Watchdog Configuration	Analog input setting window watchdog timeout (8.5–205 ms range) via external resistor; open-circuit configures longest period.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LIN SBC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC33912G5AC	Same pinout and core functionality; adds CAN transceiver and enhanced watchdog features; higher quiescent current in Stop mode (120 µA vs. 62 µA).	Required where CAN+LIN coexistence is needed (e.g., gateway modules); not drop-in due to added CAN pins and different interrupt handling.	Select MC33912G5AC only if CAN bus integration is mandatory; otherwise MC33910G5AC offers lower cost and better sleep efficiency.
TLIN1022DSWR	Standalone LIN transceiver (no regulators, no HS drivers); 3.3 V I/O compatible; smaller 8-pin SOIC package; no integrated diagnostics or wake-up inputs.	Used when MCU already provides power and drive capability; lacks system-level integration - requires external LDO, FETs, and wake-up circuitry.	Choose TLIN1022DSWR for minimal footprint and cost in simple LIN node designs; MC33910G5AC preferred for full SBC consolidation.

Compared with MC33912G5AC and TLIN1022DSWR, MC33910G5AC uniquely balances integrated power, drive, and communication in a single 32-pin LQFP - delivering lowest component count for LIN-based body electronics without sacrificing diagnostic depth or automotive qualification.

FAQ

What is the maximum LIN data rate supported by the MC33910G5AC?

The MC33910G5AC supports LIN data rates up to 100 kbps when waveshaping is disabled. With waveshaping enabled, it complies with LIN Physical Layer Specification at standard 20.0 kbps (normal slew) and 10.4 kbps (slow slew) - all while meeting SAE J2602-2 conformance requirements for automotive deployment.

Does the MC33910G5AC include built-in protection features for its high-side drivers?

Yes, the MC33910G5AC includes comprehensive protection for HS1 and HS2: overcurrent limiting (60–250 mA), open-load detection (5–7.5 mA), short-circuit shutdown (threshold at VSUP − 2.0 V), and overtemperature shutdown (140–180 °C). All fault conditions set corresponding bits in the High-Side Status Register (HSSR) accessible via SPI.

How does the MC33910G5AC manage power states to minimize battery drain?

The MC33910G5AC implements three power modes: Normal (4.5–10 mA supply current), Stop (62 µA at 13.5 V), and Sleep (33 µA at 13.5 V). Wake-up is supported via LIN bus activity, L1 input, cyclic sense, or forced wake-up - enabling ultra-low standby consumption while maintaining responsiveness in always-on vehicle subsystems.

Can the MC33910G5AC monitor battery voltage directly?

Yes, the MC33910G5AC features a dedicated VSENSE pin that connects directly to the battery rail. Internal 5.25× voltage division routes scaled battery voltage to ADOUT0, allowing host MCU ADC measurement with ±30 mV offset accuracy - enabling real-time battery health monitoring without external components.

What is the purpose of the WDCONF pin on the MC33910G5AC?

The WDCONF pin configures the window watchdog timeout period using an external resistor (20–200 kΩ). It enables programmable watchdog periods from 8.5 ms to 205 ms - critical for detecting MCU firmware hangs in safety-critical automotive functions while avoiding false resets during legitimate long-latency operations.
