STMicroelectronics EVAL-VNH5019-P2

Overview

EVAL-VNH5019-P2 from STMicroelectronics is an evaluation board for the VNH5019A-E automotive-grade H-bridge motor driver IC, designed to drive brushed DC motors up to 30 A continuous current at 41 V max supply, with integrated current sensing, thermal shutdown, and reverse-battery protection via external N-MOS. It supports PWM operation up to 20 kHz and is qualified per AEC-Q100 Grade 0 (−40 °C to +150 °C).

For engineers reviewing the EVAL-VNH5019-P2 datasheet, EVAL-VNH5019-P2 pinout, EVAL-VNH5019-P2 application, or EVAL-VNH5019-P2 equivalent, this board enables rapid validation of motor control logic, fault diagnostics (via DIAG/ENA pins), current-sense calibration (CS/CS_DIS), and thermal behavior under real load conditions in automotive body electronics and industrial actuation systems.

Technical Context

The EVAL-VNH5019-P2 implements a full-bridge topology using the VNH5019A-E IC, which integrates dual high-side VIPower® M0 drivers and two low-side MOSFETs in a MultiPowerSO-30™ package with electrically isolated leadframes and exposed thermal pads. It supports both clockwise (INA) and counter-clockwise (INB) motor direction control, brake mode, and independent half-bridge enable/disable via ENA/DIAGA and ENB/DIAGB pins.

Key functional blocks include a charge pump (CP pin) for driving an external reverse-polarity N-MOS, analog current sense (CS pin, K₀ = 4670–10110 A/A typical), and comprehensive protection: undervoltage (4.5 V) / overvoltage (24–30 V) lockout, high-side/low-side thermal shutdown (150–200 °C), cross-conduction prevention, and short-to-ground/battery detection with latched fault signaling.

FAQ

Does EVAL-VNH5019-P2 include the VNH5019A-E IC pre-mounted?

Yes. The EVAL-VNH5019-P2 board comes fully assembled with one VNH5019A-E IC in MultiPowerSO-30™ package, all required decoupling capacitors, pull-up resistors for ENA/DIAGA and ENB/DIAGB, current-sense resistor network, and solder points for external reverse-polarity N-MOS and motor connections. No additional IC mounting is needed for evaluation.

What motor types and maximum loads can be tested on this board?

EVAL-VNH5019-P2 supports brushed DC motors with continuous current ≤30 A and supply voltage ≤24 V nominal (41 V absolute max). It has been validated with 12 V/24 V automotive motors used in power windows, sunroofs, and seat adjusters. Peak currents above 30 A are limited by internal current sense and thermal shutdown; sustained loads require external heatsinking per ST's MultiPowerSO-30™ thermal guidelines.

How is reverse battery protection implemented on this evaluation board?

Reverse battery protection is not built-in but enabled via the CP pin, which delivers a regulated gate drive voltage (~10 V) to an external N-channel PowerMOS (not included). When wired per Figure 4 or 5 in the datasheet, that external MOS blocks reverse current flow. The board provides dedicated pads and routing for CP, VBAT, and the MOS source/drain-users must select and solder a suitable 40 V+ N-MOS with R_DS(on) < 5 mΩ for <1 W dissipation.

Can EVAL-VNH5019-P2 be used for closed-loop current control?

Yes. The CS pin outputs a proportional current (I_SENSE) with gain K₀ ≈ 7110 A/A (typ.) at 3 A motor current. By connecting a precision shunt resistor (e.g., 100 mΩ) between CS and ground, users generate a measurable analog voltage (e.g., 0.3 V at 3 A) for ADC feedback. CS_DIS must be driven high to disable sensing or left open/low to enable it-enabling real-time current monitoring and PID-based torque regulation.
