For engineers reviewing the MC34910G5AC datasheet, MC34910G5AC pinout, MC34910G5AC application, or MC34910G5AC equivalent, this product page delivers verified technical context, real-world operating mode behavior (Normal/Sleep/Stop), LIN conformance to SAE J2602-2, and precise thermal limits (–40 °C to +85 °C ambient).
Technical Context
The MC34910G5AC implements a SPI-controlled architecture with full-duplex interface up to 4.0 MHz, supporting diagnostics via readable status registers and configurable wake-up sources (LIN bus, L1, cyclic sense, forced wake-up). Its LIN physical layer complies with ISO 17987-4 and SAE J2602-2, featuring programmable waveshaping and ±6.0 kV ESD protection on LIN per IEC 61000-4-2 (150 pF/330 Ω).
It operates in three distinct power modes: Normal (full functionality), Sleep (VDD off, wake-up via LIN/L1/cyclic sense), and Stop (VDD on, limited current, wake-up via CS/LIN/L1/cyclic sense/external reset). The device includes integrated overtemperature prewarning (90–140 °C) and shutdown (150–190 °C), plus battery voltage sensing (VSENSE) and Hall sensor supply (HVDD, 5.0 V, 35 mA typical).

Pinout & Package
MC34910G5AC uses a 32-pin LQFP package (7 mm × 7 mm, 0.8 mm pitch) with exposed thermal pad. Pin functions are validated per NXP MC33910G5 datasheet (Rev. 9.0, pp. 6–7), where MC34910G5AC shares identical pinout and electrical definitions with MC33910G5AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RXD / TXD | LIN Transceiver I/O | Half-duplex bidirectional LIN bus interface; RXD reports bus state to MCU, TXD controls driver output. |
| MISO / MOSI / SCLK / CS | SPI Interface | Full-duplex serial control: CS enables communication; MISO/MOSI transfer register data; SCLK synchronizes transfers up to 4 MHz. |
| HS1 / HS2 | High-Side Switch Outputs | Drives loads directly from VS2 rail; supports PWM modulation via PWMIN; includes current limiting, open-load, and thermal shutdown reporting. |
| L1 | Wake-up & Analog Input | Digital wake-up source (with 33 kΩ series resistor); also routed to analog multiplexer for battery-sense or contact-monitoring via ADOUT0. |
| VDD / HVDD | Regulated Outputs | VDD = main 5.0 V supply (60 mA); HVDD = switchable 5.0 V Hall sensor output (35 mA typ), both with fault reporting and LVR. |
| VSENSE | Battery Voltage Sense | Direct connection to battery line (–27 V to +40 V tolerant); internal 5.25× divider feeds ADOUT0 for accurate system voltage monitoring. |
| IRQ / RST | Interrupt & Reset Control | IRQ signals wake-up/events (active-low); RST is bidirectional - driven low during internal resets, configurable as input or output. |
| WDCONF | Watchdog Configuration | External resistor sets window watchdog period (8.5–205 ms); open pin disables watchdog - critical for fail-safe MCU supervision. |
Key Features
| Feature | Design Value |
|---|---|
| LIN Transceiver with J2602 Support | Enables SAE J2602-2 conformance testing including undervoltage hysteresis (400 mV) and deglitch timing (35–70 µs), ensuring robust operation in noisy 12 V systems. |
| Dual High-Side Drivers with Diagnostics | HS1/HS2 provide real-time fault flags (HSxCL, HSxOP, HSOT) via SPI-readable HSSR register - eliminates need for external current-sense circuitry. |
| Configurable Cyclic Sense Mode | Enables ultra-low-power wake-up polling (27–300 µA sleep current) at user-defined intervals - extends battery life in always-on vehicle modules. |
| Integrated VSENSE & L1 Analog Multiplexing | Single ADOUT0 pin outputs scaled VSENSE (5.25×) or L1 (1.0× or 3.6×), reducing BOM count and PCB area versus discrete ADC solutions. |
| Thermal Protection with Prewarning | Overtemperature prewarning interrupt (TPRE = 90–140 °C) allows MCU to throttle loads before shutdown (TSD = 150–190 °C), improving system reliability. |

FAQ
What is the maximum ambient temperature rating for MC34910G5AC?
The MC34910G5AC is rated for operation from –40 °C to +85 °C ambient temperature, as specified in Table 3 of the MC33910 datasheet Rev. 9.0. This distinguishes it from the MC33910G5AC/R2 variant, which supports up to +125 °C ambient. The junction temperature limit remains 150 °C across both variants.
Does MC34910G5AC support SAE J2602-2 conformance testing?
Yes, MC34910G5AC explicitly supports SAE J2602-2 conformance, including LIN undervoltage thresholds (5.0–6.0 V), hysteresis (400 mV), and deglitch timing (35–70 µs), as documented in Section 4.2 of the MC33910 datasheet. This capability is enabled by the DIS_J2602 bit and is absent in the MC34910BAC variant.
How does the L1 pin function in MC34910G5AC?
In MC34910G5AC, the L1 pin serves dual roles: as a digital wake-up input (with 33 kΩ series resistor per datasheet note) and as an analog input routed through an internal multiplexer. Its voltage is divided by selectable ratios (1.0× or 3.6×) and appears on ADOUT0, enabling contact monitoring or battery-sense functionality without external components.
What is the purpose of the WDCONF pin on MC34910G5AC?
The WDCONF pin on MC34910G5AC configures the window watchdog period using an external resistor (20–200 kΩ), yielding timing ranges from 8.5 ms to 205 ms. Leaving WDCONF open disables the watchdog entirely. This pin enables flexible, hardware-based MCU supervision without firmware dependency - a critical safety feature in automotive systems.
Can MC34910G5AC drive Hall effect sensors directly?
Yes, MC34910G5AC provides a dedicated 5.0 V, 35 mA typical switched output (HVDD) optimized for Hall effect sensors. It includes fault reporting (HVDDOK flag), dropout voltage ≤300 mV at 15 mA, and requires only a 1.0–10 µF external capacitor (ESR < 5 Ω) - meeting common Hall sensor supply requirements without additional regulation.
