STMicroelectronics VNH2SP30TR-E

Overview

VNH2SP30TR-E from STMicroelectronics is an AEC-Q100 qualified automotive H-bridge motor driver integrating dual high-side VIPower™ M0 drivers and two vertical EHD 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 (K ≈ 11,370 A/A), thermal shutdown (150–200 °C), and overvoltage clamp (43–54 V). It is used for bidirectional DC motor control in power seats, HVAC actuators, and electronic throttle bodies.

For engineers reviewing the VNH2SP30TR-E datasheet, VNH2SP30TR-E pinout, VNH2SP30TR-E application, or VNH2SP30TR-E equivalent, key selection criteria include its 19 mΩ max R_DS(on) per leg, dual open-drain diagnostic/enable pins (ENA/DIAGA & ENB/DIAGB), linear current limiting architecture, ECOPACK®-compliant MultiPowerSO-30 thermal package, and fault signaling via pull-low DIAG outputs under overtemperature or short-circuit conditions.

Technical Context

The device implements a fully integrated half-bridge pair with independent logic-controlled high-side (VIPower™ M0) and low-side (EHD) power stages per channel. Each leg includes cross-conduction protection, dynamic current limiting via gate-source voltage reduction, and dedicated undervoltage (5.5 V) and overvoltage (16–22 V) shutdown thresholds.

Current sensing is analog and proportional (K₁ = 9665–13075 A/A at 30 A), referenced to ground and delivered as a sourcing current on CS pin. Diagnostic feedback is implemented through two open-drain pins (ENA/DIAGA and ENB/DIAGB) that assert low during thermal fault, loss of ground, or excessive V_DS on low-side FETs - enabling real-time system-level fault isolation without external comparators.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable PWM frequency for VNH2SP30TR-E?

The device supports PWM operation up to 20 kHz, as confirmed in the datasheet's Table 9 and Figure 36–37 waveforms. Operating beyond this frequency risks incomplete switching transitions, increased dynamic losses, and potential violation of the minimum off-time requirement (6 µs) needed to avoid false short-to-battery detection.

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

The CS pin sources a current (I_SENSE = I_MOTOR/K) proportional to motor current. To convert to voltage, connect a precision resistor (e.g., 1.5 kΩ) from CS to GNDA; the resulting voltage (V_SENSE = I_SENSE × R_SENSE) is ratiometric and directly readable by an ADC. No external op-amp or isolation is required.

Can ENA/DIAGA and ENB/DIAGB be used simultaneously as inputs and outputs?

Yes - these pins are bidirectional open-drain terminals. When externally pulled high (e.g., via 10 kΩ to 5 V), they act as enable inputs; when the device detects a fault (thermal, overcurrent, or loss-of-ground), it actively pulls them low to signal the MCU. No additional direction control logic is needed.

Is external reverse-battery protection required for VNH2SP30TR-E?

No - the device integrates reverse-battery protection circuitry as described in Section 3.1 of the datasheet. It withstands –14 V applied to VCC with respect to GNDA/GNDB without damage or latch-up, eliminating the need for external MOSFET-based protection in standard 12 V automotive installations.
