Product details

Overview

VNH2SP30-E from STMicroelectronics is an AEC-Q100 qualified automotive H-bridge motor driver integrating dual high-side VIPower™ M0 switches and two vertical low-side EHD MOSFETs in a single MultiPowerSO-30 package. It delivers 30 A continuous output current, supports PWM up to 20 kHz, and provides real-time current sensing via the CS pin with ±8% analog drift over temperature. It is used in power seat actuators, HVAC damper controls, and electronic parking brake modules.

For engineers reviewing the VNH2SP30-E datasheet, VNH2SP30-E pinout, VNH2SP30-E application, or VNH2SP30-E equivalent, this page delivers verified electrical parameters, thermal performance data, fault diagnostic behavior, and automotive-grade protection features - all confirmed against ST's production datasheet DocID10832 Rev 10.

Technical Context

The device implements a fully integrated half-bridge pair (A and B) with independent logic inputs (INA/INB), enable/diagnostic pins (ENA/DIAGA and ENB/DIAGB), and shared PWM control. Each leg combines a monolithic high-side driver using VIPower™ M0 technology and a low-side vertical MOSFET fabricated with STripFET™ EHD process, enabling <19 mΩ R_DS(on) per leg at T_j = 25°C.

Protection architecture includes undervoltage lockout (4.7 V reset, 5.5 V shutdown), overvoltage clamp (up to 48 V total V_CLP), thermal shutdown (150–200 °C trip), cross-conduction prevention, and linear current limiting triggered by excessive V_DS on low-side FETs. Faults pull ENx/DIAGx low via open-drain outputs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	5.5 V to 16 V operating supply; 41 V absolute max - enables direct battery connection with transient tolerance.
I_OUT Continuous	30 A per channel - supports high-torque DC motors in automotive body electronics.
R_DS(on) Max	19 mΩ per leg (high + low side combined) - minimizes conduction loss and thermal rise at full load.
PWM Frequency	DC to 20 kHz - allows smooth speed control without audible noise in cabin applications.
Current Sense Gain	K = 9.7–13.1 kA/A (I_OUT/I_SENSE) - delivers precise analog feedback for closed-loop motor current regulation.
Thermal Shutdown	150–200 °C trip range with 7–15 °C hysteresis - prevents irreversible die damage during sustained overload.
Logic Compatibility	5 V CMOS-level inputs (V_IL ≤ 1.25 V, V_IH ≥ 3.25 V) - interfaces directly with automotive microcontrollers without level-shifting.

Pinout & Package

Package: MultiPowerSO-30™ - thermally enhanced 30-pin exposed-pad power SO package with three electrically isolated leadframes (Heat Slug1/VCC, Heat Slug2/OUTB, Heat Slug3/OUTA) for superior junction-to-ambient thermal resistance in harsh automotive environments.

Pin/Terminal	Circuit Role	Design Meaning
OUTA / Pins 1,25,30	High-side source / Low-side drain (Leg A)	Primary motor phase A power terminal; connects to motor winding and shares thermal slug with heat dissipation path.
OUTB / Pins 15,16,21	High-side source / Low-side drain (Leg B)	Primary motor phase B power terminal; symmetric layout enables balanced PCB routing and thermal management.
VCC / Pins 3,13,23	Battery input & high-side drain	Distributes 12 V battery rail to both high-side switches; routed to central thermal slug for lowest R_θJA.
GNDA / Pins 26,27,28	Low-side A source	Return path for Leg A current; must be externally tied to GNDB to ensure common reference and avoid ground loop faults.
GNDB / Pins 18,19,20	Low-side B source	Return path for Leg B current; external tie to GNDA required for proper current sense accuracy and fault detection.
INA / Pin 5	Direction control (clockwise)	CMOS-compatible input with hysteresis; sets forward rotation when INB = low and PWM active.
INB / Pin 11	Direction control (counter-clockwise)	CMOS-compatible input with hysteresis; sets reverse rotation when INA = low and PWM active.
PWM / Pin 8	Speed modulation input	Controls duty cycle of low-side FETs; low state forces both LSA/LSB off regardless of INA/INB state.
CS / Pin 9	Analog current sense output	Sources proportional current (I_SENSE = I_OUT/K); requires external resistor to convert to voltage for ADC sampling.
ENA/DIAGA / Pin 6	Enable & fault indicator (Leg A)	Open-drain bidirectional pin: pulled high externally to enable Leg A; pulled low internally on thermal or overcurrent fault.
ENB/DIAGB / Pin 10	Enable & fault indicator (Leg B)	Open-drain bidirectional pin: pulled high externally to enable Leg B; pulled low internally on thermal or overcurrent fault.

Key Features

Feature	Design Value
AEC-Q100 qualification	Qualified to Grade 0 (-40 °C to +150 °C ambient), meeting automotive reliability and stress test requirements.
Integrated linear current limiter	Reduces high-side gate voltage dynamically during short-circuit events - avoids destructive current spikes without external components.
Loss-of-ground & loss-of-V_CC protection	Detects open-circuit conditions on GNDA/GNDB or VCC lines and disables affected leg - prevents erratic switching and shoot-through.
Overvoltage clamp (43–54 V)	Clamps transients above battery nominal voltage using internal Zener-like structure - eliminates need for external TVS diodes.
Very low standby current (≤60 µA)	Minimizes battery drain in sleep mode - critical for always-on automotive modules like seat memory systems.

Applications

Power Seat Actuation

HVAC Damper Control

Use Scenario: Bidirectional positioning of automotive power seat mechanisms using 12 V DC motors.

Use Value: Eliminates need for discrete protection circuitry while maintaining <19 mΩ R_DS(on) - ensures efficient operation even at elevated under-hood temperatures.

Electronic Parking Brake (EPB)

Steering Column Adjustment

Use Scenario: Actuating caliper-mounted motors in fail-safe parking brake systems requiring high-reliability torque delivery.

IC Role / Device Role / Timing Role: Dual-leg driver providing redundant control paths (Leg A/B), with independent DIAG outputs for ASIL-B fault diagnostics and current feedback for brake engagement verification.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DRV8872PWPR	Single H-bridge, 3.6 A max continuous, no integrated current sense, QFN-16 package	Targeted at low-power consumer robotics; lacks AEC-Q100 qualification and automotive thermal robustness	Select only for non-automotive, low-current (<5 A) applications where cost and size outweigh reliability needs.
MPQ6532-AEC1	30 V max V_CC, 10 A continuous, integrated current sense, 4 mm × 4 mm QFN, AEC-Q100 Grade 1	Lower current rating and smaller thermal mass - unsuitable for sustained 30 A loads or high-temperature under-hood use	Consider for space-constrained cabin modules where peak current stays below 10 A and ambient T_a ≤ 105 °C.

Compared with DRV8872PWPR and MPQ6532-AEC1, the VNH2SP30-E uniquely combines 30 A capability, AEC-Q100 Grade 0 qualification, multi-slug thermal packaging, and diagnostic-ready open-drain enable/fault pins - making it the only option validated for high-power, high-reliability automotive motion control.

FAQ

What is the maximum allowable PWM frequency for VNH2SP30-E?

The VNH2SP30-E supports PWM frequencies from DC up to 20 kHz, as specified in Table 9 of the datasheet. Operation beyond 20 kHz risks violating minimum off-time requirements (≥6 µs) and may trigger false short-to-battery detection due to insufficient low-state duration for internal timing circuits.

How does the current sense output (CS pin) interface with a microcontroller?

The CS pin sources a current (I_SENSE = I_OUT/K) proportional to motor current. To interface with an MCU ADC, connect a precision resistor (e.g., 1.5 kΩ) from CS to ground; the resulting voltage (V_SENSE = I_SENSE × R_SENSE) ranges from 0–450 mV at 30 A, with ±8% gain drift over temperature.

Can VNH2SP30-E drive a unidirectional motor in half-bridge mode?

Yes - configure one leg (e.g., Leg A) as active H-bridge and disable the other (Leg B) by holding ENB/DIAGB low. The device supports half-bridge operation per Table 34 (application note AN4724), with OUTA and GNDA forming the power path and INA/PWM controlling direction/speed.

What happens during thermal shutdown, and how is recovery handled?

When junction temperature exceeds 150–200 °C, the affected high-side switch shuts off and its corresponding ENx/DIAGx pin is pulled low. Recovery occurs automatically after junction cools below the thermal reset threshold (135 °C typical), provided VCC remains within 5.5–16 V and no other faults persist - no external reset signal is required.
