Product details

Overview

VN9D30Q100FTR from STMicroelectronics is a 6-channel automotive high-side driver IC built on VIPower M0-7 technology, designed for direct ground-referenced resistive/inductive load control in engine management, body electronics, and chassis systems. It delivers 31.5 A peak current on Channel 0 (RON = 33 mΩ) and 14 A on Channels 1–5 (RON = 90 mΩ), operates down to 3.5 V for cold-cranking compliance (LV124 Rev. 2013), and integrates 24-bit SPI, 10-bit ADC-based digital current sensing, and independent PWM generation per channel.

For engineers reviewing the VN9D30Q100FTR datasheet, VN9D30Q100FTR pinout, VN9D30Q100FTR application, or VN9D30Q100FTR equivalent, this device supports fail-safe limp-home operation via DI0/DI1 direct inputs, real-time diagnostics (open-load, short-to-VCC/GND, overtemperature), and programmable power limitation with auto-restart or latch-off behavior - critical for ASIL-B compliant power distribution units.

Technical Context

This device implements six independent high-side switches with integrated protection logic, thermal shutdown with configurable response (latch-off or time-limited auto-restart), and dual-mode diagnostic architecture: synchronous fault detection (overload, short-circuit) plus asynchronous ADC-based current monitoring. Its 24-bit SPI interface supports register-level access to control, status, and trimming registers including OTP-configurable DIx assignment and PWM phase-shift settings.

The internal architecture includes a dedicated voltage regulator (VDD = 3.3 V or 5 V compatible), backside thermal TAB connected to VCC, and hardware-level fail-safe state machine that activates when VDD drops below POR threshold or watchdog timeout occurs. Limp-home mode assigns OUT0/OUT5 to DI0 and OUT1–OUT4 to DI1 by default, enabling deterministic output behavior without SPI communication.

Key Specifications

Parameter	Value and Actual Design Meaning
Channel count	6 independent high-side outputs with individual control and diagnostics
VCC operating range	3.5 V to 28 V - enables deep cold-cranking support per LV124 Rev. 2013
RON typ. (Ch0)	33 mΩ - limits conduction loss to ≤1.0 W at 31.5 A, reducing thermal stress
RON typ. (Ch1–5)	90 mΩ - optimized for 14 A medium-power loads like solenoids and valves
Current sense resolution	10-bit ADC with 0.1% FSR accuracy - enables ±12.8 mA precision at 14 A full scale
SPI interface	24-bit frame, CMOS-compatible CSN/SCK/SDI/SDO - supports daisy-chaining and CRC-protected register access
Thermal protection	Programmable overtemperature response: latch-off or auto-restart within user-defined time window

Pinout & Package

Package: QFN 6 × 6 mm, 32-pin, exposed thermal TAB electrically connected to VCC (pin Tab). The TAB must be soldered but electrically isolated on PCB for thermal performance and EMI control.

Pin/Terminal	Circuit Role	Design Meaning
Tab	VCC power connection & thermal path	Direct drain connection of all six Power MOSFETs; requires PCB copper pour for heatsinking
OUT0–OUT5 (pins 3–4, 21–22, 25–26, 27–28, 29–30, 31–32)	High-side output terminals	Paired pins per channel for low-inductance routing; each connects directly to load anode
DI0, DI1 (pins 9–10)	Direct input control	OTP-programmable assignment to drive specific outputs during limp-home/fail-safe modes
CSN, SCK, SDI, SDO (pins 12–15)	24-bit SPI interface	CMOS-level serial bus supporting daisy-chain configuration and register read/write
VDD (pin 16)	Digital supply input	Accepts 3.3 V or 5 V; powers internal logic, SPI, and ADC - independent of VCC rail
GND (pin 17)	Digital ground reference	Separate from power ground; must be routed with low impedance to minimize noise coupling into ADC

Key Features

Feature	Design Value
Deep cold-cranking operation	Functional down to 3.5 V VCC - meets LV124 Rev. 2013 requirements for automotive battery drop scenarios
Dual-mode diagnostic architecture	Synchronous fault detection + asynchronous 10-bit ADC current sense - enables both real-time protection and precise load monitoring
Configurable limp-home behavior	OTP-programmed DIx mapping and register-defined output states ensure deterministic fail-operational response without MCU intervention
Independent PWM engine	Per-channel phase shift (5-bit resolution) and frequency division (1/512 to 1/4096) - eliminates external timing components for LED dimming or solenoid control
Load dump protection	Integrated clamp circuit withstands ISO 7637-2 Pulse 5a (75 V/350 ms) - eliminates need for external TVS on VCC line

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS7004-1EPP	4-channel, 40 mΩ RON max, no integrated ADC or PWM engine - requires external current sense and timing circuitry	Limited to simpler load types without closed-loop control needs; lacks limp-home mode and SPI diagnostics	Choose for cost-sensitive 4-output applications where diagnostic depth and fail-operational behavior are not required
NXP MC33883A	8-channel, 100 mΩ RON typ., SPI interface only (no direct inputs), no integrated ADC - relies on external shunt + op-amp for current sense	Suitable for non-automotive industrial use; lacks AEC-Q100 qualification and LV124 cold-cranking support	Prefer for multi-channel industrial motor control where automotive qualification is unnecessary and external sensing is acceptable

Compared with INFINEON BTS7004-1EPP and NXP MC33883A, VN9D30Q100FTR provides superior integration (on-die ADC, PWM, limp-home logic), deeper cold-cranking margin, and richer diagnostic coverage - making it optimal for ASIL-B power distribution nodes where functional safety and design simplification are prioritized.

FAQ

What is the maximum continuous current rating per channel?

Channel 0 supports 31.5 A continuous current with RON = 33 mΩ at TJ = 25°C; Channels 1–5 support 14 A continuous current with RON = 90 mΩ. Derating applies above 25°C ambient - full thermal data is provided in DS13246 Section 7.2 (Thermal Characteristics).

How does the limp-home mode function without SPI communication?

Limp-home mode activates automatically during VDD brownout, watchdog timeout, or MCU reset. Outputs are controlled solely by DI0/DI1 pins per OTP-defined mapping - OUT0/OUT5 follow DI0, OUT1–OUT4 follow DI1 - with all protections (overcurrent, overtemperature, open-load) fully active and independent of SPI.

Can the integrated ADC measure load current accurately under PWM operation?

Yes - the 10-bit ADC samples current synchronously with PWM edges using programmable blanking windows (Section 6.2 of DS13246), rejecting switching noise. Accuracy remains ±0.1% FSR across 0–14 A range with proper PCB layout and decoupling on VDD and analog ground.

Is the VN9D30Q100FTR compliant with AEC-Q100 Grade 0 or Grade 1?

VN9D30Q100FTR is qualified to AEC-Q100 Grade 1 (−40°C to +125°C ambient), with extended junction temperature capability up to +150°C. This enables deployment in under-hood locations such as engine compartments and transmission control units.
