Product details

Overview

VNH3SP30TR-E from STMicroelectronics is an AEC-Q100 qualified automotive full-bridge motor driver integrating dual high-side VIPower™ M0-3 switches and two vertical low-side EHD MOSFETs in a MultiPowerSO-30 package. It delivers 30 A continuous output current, supports 5 V logic-level inputs, and operates up to 10 kHz PWM for bidirectional DC motor control in power seat, sunroof, and HVAC actuators.

For engineers reviewing the VNH3SP30TR-E datasheet, VNH3SP30TR-E pinout, VNH3SP30TR-E application, or VNH3SP30TR-E equivalent, key selection criteria include R_DS(on) per leg (45 mΩ max), thermal shutdown at 150 °C, undervoltage/overvoltage lockout (5.5–36 V), cross-conduction protection, and open-drain diagnostic enable pins with fault reporting capability.

Technical Context

The device implements independent half-bridge legs with dedicated INA/INB direction control and shared PWM modulation on low-side FETs. Each leg integrates linear current limiting via gate-source voltage reduction during overcurrent events and features separate open-drain ENA/DIAGA and ENB/DIAGB pins that serve as both enable inputs (with external pull-up) and fault indicators (pulled low on thermal shutdown or excessive V_DS).

Protection architecture includes undervoltage (5.5 V) and overvoltage (36 V) shutdown, overvoltage clamping on both high- and low-side paths, loss-of-ground and loss-of-V_CC detection, and thermal shutdown with 15 °C hysteresis. The MultiPowerSO-30 package uses electrically isolated lead frames with exposed die pads for enhanced thermal dissipation in harsh automotive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Current	30 A continuous per leg - enables direct drive of high-torque automotive DC motors without external heatsinking under typical ambient conditions.
R_DS(on) (HS + LS)	45 mΩ max per leg at T_j = 25 °C - ensures <1.7 W conduction loss at 30 A, critical for thermal management in enclosed modules.
Supply Voltage Range	5.5 V to 36 V - covers full automotive battery range including cold-crank (6 V) and load-dump (40 V transient) with internal clamp protection.
PWM Frequency	DC to 10 kHz - supports smooth speed control and audible-noise suppression in cabin applications.
Logic Input Compatibility	5 V CMOS with hysteresis - eliminates need for level-shifting when interfacing with standard microcontrollers.
Thermal Shutdown Threshold	150 °C junction temperature - protects VIPower™ die from irreversible damage during sustained overload or poor PCB thermal design.
Diagnostic Output	Open-drain ENA/DIAGA & ENB/DIAGB - provides real-time fault signaling (thermal, overcurrent, supply fault) without additional interface circuitry.

Pinout & Package

Package: MultiPowerSO-30™ - thermally optimized 30-pin power SO package with three exposed heat slugs (OUTA/VCC/OUTB) and electrically isolated lead frames for high-current automotive operation.

Pin/Terminal	Circuit Role	Design Meaning
1, 25, 30 (OUTA)	High-side source / Low-side drain node A	Power connection to motor terminal A; shares thermal slug with VCC and OUTB for symmetrical heat spreading.
3, 13, 23 (VCC)	Battery supply input	Main 5.5–36 V power rail; connects directly to high-side drains and supplies internal logic and drivers.
6 (ENA/DIAGA)	Half-bridge A enable & fault indicator	Open-drain bidirectional pin: pulled high externally to enable leg A; pulled low internally on fault (thermal, overcurrent, supply).
5 (INA)	Clockwise direction control	CMOS-compatible input with hysteresis; defines forward motor rotation when INB = 0 and PWM active.
8 (PWM)	Low-side gate modulation input	Drives low-side FETs only; high level turns on LSB/LSA depending on INA/INB state; low level forces both off.
11 (INB)	Counterclockwise direction control	CMOS-compatible input with hysteresis; defines reverse motor rotation when INA = 0 and PWM active.
10 (ENB/DIAGB)	Half-bridge B enable & fault indicator	Open-drain bidirectional pin: identical function to ENA/DIAGA but for leg B.
15, 16, 21 (OUTB)	High-side source / Low-side drain node B	Power connection to motor terminal B; shares thermal slug with OUTA and VCC for balanced thermal performance.
26–28 (GNDA), 18–20 (GNDB)	Low-side source terminals	Must be externally shorted together; provide return path for motor current and internal protection sensing.

Key Features

Feature	Design Value
Integrated linear current limiter	Reduces high-side gate voltage during short-circuit to limit peak current to 30–45 A without external sense resistor or controller intervention.
Loss-of-ground and loss-of-V_CC detection	Prevents unintended switching or latch-up if ground or supply connections degrade - critical for functional safety compliance.
Cross-conduction protection	Hardware-enforced dead-time prevents shoot-through by disabling opposite switch during state transitions.
Very low standby power	20–40 µA supply current in off-state - meets automotive "always-on" module requirements for battery drain minimization.
ISO 7637-2 pulse immunity	Withstands Level IV load dump (86.5 V, 400 ms) and pulse 1/2/3a/3b transients per automotive EMC standards without external suppressors.

Applications

Use Value: Achieves <25 dB(A) acoustic emission at 1 m distance due to precise edge control (t_r/t_f = 1.5–5 µs) and absence of external gate drivers.

HVAC Blower Control

Electric Parking Brake (EPB) Actuator

Use Scenario: Variable-speed control of centrifugal blowers in climate control systems requiring wide dynamic range and rapid response.

IC Role / Device Role / Timing Role: High-efficiency motor driver supporting 0–100% duty cycle PWM with fast turn-on/turn-off delay (<300 µs) for responsive airflow adjustment.

Equivalent & Alternatives

The following parts are listed as comparable options for similar full-bridge motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DRV8872PWPR	Lower current rating (3.6 A), no AEC-Q100 qualification, smaller HTSSOP-20 package	Targeted at consumer robotics and industrial benchtop tools - lacks automotive transient immunity and thermal robustness	Select only for non-automotive, low-power applications where cost and board space outweigh reliability requirements.
MPQ6532-AEC1	30 A rating, AEC-Q100 Grade 1, integrated current sense amplifier, but no open-drain diagnostic pins	Used in EPS assist modules where analog current feedback is required but discrete fault signaling is acceptable	Choose when analog current monitoring is mandatory and diagnostic pin simplicity is secondary to measurement precision.

Compared with DRV8872PWPR and MPQ6532-AEC1, the VNH3SP30TR-E uniquely combines AEC-Q100 Grade 0 qualification, dual open-drain diagnostic outputs, and 30 A capability in a thermally optimized MultiPowerSO-30 package - making it the only option qualified for under-hood, high-reliability automotive motion control.

FAQ

What is the maximum allowable junction temperature before thermal shutdown activates?

The VNH3SP30TR-E triggers thermal shutdown at 150 °C junction temperature, with a reset threshold of 135 °C and 15 °C hysteresis. This threshold is fixed by internal bandgap reference and cannot be adjusted externally. Operation above 150 °C causes immediate disablement of the affected high-side switch to prevent die damage, and recovery occurs only after junction temperature falls below 135 °C.

Can the device operate with a 3.3 V microcontroller without level shifters?

No - the VNH3SP30TR-E requires minimum 3.25 V high-level input voltage (V_IH) on INA, INB, PWM, ENA/DIAGA, and ENB/DIAGB pins. A 3.3 V MCU may meet this marginally at room temperature but fails under voltage drop, temperature drift, or noise. ST recommends using 5 V logic or adding a single-transistor level shifter to ensure reliable operation across -40 °C to 125 °C ambient.

How does the linear current limiter function differ from traditional overcurrent shutdown?

Unlike instantaneous shutdown, the linear current limiter dynamically reduces the high-side gate-source voltage during overcurrent events, holding output current near 30–45 A without turning off the bridge. This maintains motor torque during brief surges (e.g., gear engagement) while preventing thermal runaway. Limiting remains active until current drops below threshold or thermal shutdown intervenes.

Is external reverse-battery protection required when using VNH3SP30TR-E?

No - the device integrates reverse-battery protection via internal diodes and clamp circuitry, validated per ISO 16750-2. It withstands -14 V applied to VCC for 60 minutes without damage or functional degradation. However, external TVS diodes are still recommended on VCC for transient suppression beyond ISO 7637-2 Pulse 5 (load dump), especially in engine bay locations.
