Product details

Overview

VNH5019A-E from STMicroelectronics is an AEC-Q100 qualified automotive H-bridge motor driver integrating dual high-side VIPower® M0 switches and two low-side MOSFETs in a single MultiPowerSO-30™ package. It delivers 30 A continuous output current, supports PWM up to 20 kHz, and features integrated current sense (proportional analog output), cross-conduction protection, and thermal shutdown-designed for bidirectional DC motor control in power seats, HVAC actuators, and electronic throttle bodies.

For engineers reviewing the VNH5019A-E datasheet, VNH5019A-E pinout, VNH5019A-E application, or VNH5019A-E equivalent, this device requires attention to its dual-diagnostic ENA/DIAGA and ENB/DIAGB pins, CS_DIS-controlled current sense enable, CP-driven external reverse-polarity MOSFET, and thermally isolated lead-frame package layout for automotive-grade thermal management.

Technical Context

The VNH5019A-E implements a fully integrated half-bridge pair with independent high-side (HS) and low-side (LS) drivers per leg, using ST's VIPower® M0 technology for monolithic integration of power FETs and protection logic. Each leg provides R_DS(on) of 12 mΩ (HS) and 6 mΩ (LS) at T_j = 25°C, with separate thermal shutdown thresholds (150–200°C) for HS and LS sections.

It employs active clamp protection (V_CLPHS = 43–54 V, V_CLPLS = 27–33 V), dynamic current limiting (ILIM_H = 30–70 A), and fault detection via open-drain DIAG/EN pins that sink current during overtemperature or overload events. The charge pump (CP) output supplies gate drive for an external N-channel MOSFET to enable reverse-battery protection.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Current	30 A continuous - supports high-torque automotive actuators without external heatsinking under defined PCB copper area.
R_DS(on) (HS / LS)	12 mΩ / 6 mΩ typ at 25°C - enables <1.5 W conduction loss per leg at 15 A, critical for efficiency in 12 V systems.
PWM Frequency	DC to 20 kHz - allows smooth speed control of brushed DC motors while avoiding audible noise in cabin applications.
Current Sense Accuracy	K₀ = 4670–10110 A/A (3 A range); ±19% drift over –40 to +150°C - enables closed-loop motor current regulation with external ADC scaling.
Thermal Resistance (j-case)	HSD: 1.7 °C/W; LSD: 3.2 °C/W - confirms effective heat extraction via exposed die pads in MultiPowerSO-30™ package.
Supply Voltage Range	V_CC: 5.5–24 V; V_BAT: –16 to +41 V - accommodates cold-crank (4.5 V) and load-dump (41 V) transients per ISO 7637-2.
Fault Detection	Dual open-drain DIAG/EN pins - provide real-time per-leg fault signaling (thermal, short-to-V_BAT, short-to-GND) without microcontroller polling.

Pinout & Package

Package: MultiPowerSO-30™ - thermally enhanced power SO package with three electrically isolated exposed heat slugs (Heat Slug1: V_CC; Heat Slug2: OUTA; Heat Slug3: OUTB) enabling >100 W power dissipation with proper PCB copper area.

Pin/Terminal	Circuit Role	Design Meaning
OUTA / OUTB	H-bridge output terminals	Source of high-side switch A/B and drain of low-side switch A/B - directly connect to motor terminals; require low-inductance routing.
INA / INB	Direction control inputs	CMOS-compatible (0.9 V / 2.1 V thresholds); set clockwise/counter-clockwise rotation or brake when both high/low.
PWM	Speed control input	CMOS-compatible; modulates duty cycle on active leg; low level forces both LSA/LSB OFF regardless of INA/INB state.
ENA/DIAGA / ENB/DIAGB	Enable & diagnostic output	Open-drain; must be pulled up externally; drives low on fault (HS thermal shutdown, LS overload) - enables hardware fault latching.
CS / CS_DIS	Current sense interface	CS outputs proportional current (K₀–K₂); CS_DIS high disables output - allows selective sensing per operational mode.
CP	Charge pump output	Drives gate of external N-MOS for reverse-battery protection - eliminates need for series diode, reducing voltage drop and heat.
VBAT / VCC	Power supply inputs	VBAT connects to battery; VCC powers internal logic and high-side drivers - decoupling required per datasheet layout guidelines.
GNDA / GNDB	Low-side source returns	Must be externally joined - defines separate current return paths for each half-bridge leg to minimize ground bounce.

Key Features

Feature	Design Value
AEC-Q100 Grade 0 qualification	Validated for operation from –40°C to +150°C ambient - meets requirements for engine bay and transmission-mounted actuators.
Integrated current sense with programmable enable	CS_DIS pin allows on-demand activation - reduces quiescent current in sleep modes and avoids ADC saturation during startup.
Per-leg thermal and overload protection	Independent HS/LS shutdown with 7–15°C hysteresis - prevents oscillation during transient overloads and ensures safe recovery.
Cross-conduction prevention	Hardware-enforced dead-time insertion during direction changes - eliminates shoot-through current even with imperfect MCU timing.
Reverse-battery protection support	CP pin delivers regulated gate drive for external N-MOS - achieves <50 mV forward drop vs. >600 mV for Schottky solutions.

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
DRV887x-Q1 (TI)	Higher R_DS(on) (22 mΩ HS), no integrated charge pump; uses internal LDO instead of V_CC/V_BAT separation.	Lacks reverse-battery protection circuitry - requires external components for ISO 16750-2 compliance.	Prefer when system-level reverse protection is already implemented and lower cost outweighs thermal performance.
BTS7012-1EPA (Infineon)	Single half-bridge (not full-bridge); 40 A rating but no current sense output; different pinout and diagnostic protocol (SPI).	Requires two devices and external current sensing for full-bridge operation - increases BOM count and layout complexity.	Select only when discrete half-bridge flexibility or higher peak current is prioritized over integration and footprint.

Compared with DRV887x-Q1 and BTS7012-1EPA, the VNH5019A-E uniquely combines full-bridge integration, analog current sense, reverse-battery support via CP, and AEC-Q100 Grade 0 in one MultiPowerSO-30™ package - reducing component count and PCB area for space-constrained automotive modules.

FAQ

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

The VNH5019A-E triggers high-side thermal shutdown at a minimum of 150°C and low-side shutdown at the same threshold, with hysteresis of 7–15°C ensuring stable recovery. Shutdown occurs independently per leg, allowing continued operation of the unaffected channel during localized overheating - verified per Table 9 in the official datasheet Rev 11.

Can the CS pin be used without external components?

No - the CS pin delivers a proportional current (e.g., 3 A motor → ~0.5 mA), requiring an external sense resistor (typically 1–10 kΩ) to convert to a measurable analog voltage. The CS_DIS pin must be held low or left floating to enable output; pulling it high disables current sensing entirely, as confirmed in Table 10 and Figure 4 of the datasheet.

How does the CP pin function in reverse-battery protection?

The CP pin supplies a regulated ~10 V gate drive to an external N-channel PowerMOSFET placed between V_BAT and V_CC. When battery polarity reverses, the MOSFET remains off, blocking current flow - eliminating the 0.6 V forward drop and 2–3 W heat generation typical of series diodes. This architecture is detailed in Section 2.5 and Figure 4 of the datasheet.

Is the VNH5019A-E compatible with 3.3 V microcontrollers?

Yes - all logic inputs (INA, INB, PWM, CS_DIS, ENA/DIAGA, ENB/DIAGB) are CMOS-compatible with V_IL ≤ 0.9 V and V_VIH ≥ 2.1 V, supporting direct interfacing to 3.3 V or 5 V MCUs without level shifters. Input hysteresis of 0.15 V ensures noise immunity in automotive wiring harnesses, as specified in Table 7.
